AB  - The work investigated the equipment of tractors, attachments and combines
in a medium-sized family farm. The research was conducted on the registered family
farm "Đurković" in the village of Čestin in the municipality of Knić. The farm cultivates
arable and forage crops for feeding dairy cows and fattening oxen on an area of 44 ha.
In the sowing structure, meadows are the most represented with 20 ha (45.45%),
alfalfa 5 ha (11.36%), silage maize 3 ha (6.83%) and perko 0.4 ha (0.91%). The farm
also grows barley on 2 ha, wheat on 1.5 ha, soybeans on 0.7 ha, oats on 0.4 ha, and
peppers for processing on 40 ares. The production process is carried out with three
tractors, 22 implements, a self-propelled combine for small grains and a combine for
silage. One tractor with an average engine power of 41.4 kV works 14.67 ha of
available land with 7.33 attachments. The total available power of the tractor engine is
129.43 kW, and the energy equipment of the farm is 2.94 kW/ha, which is the average
of family farms in Serbia. If the combine engine power for small grain and silage were
added, the energy equipment would increase to 7.85 kV/ha. Combines are underutilized
because they are used only for subsistence. The average age of mechanization is over
40 years, so replacement and purchase of new agricultural machinery is not possible.

AB  - Physical properties play an important role in determining suitability of soil for agricultural, amelioration, ecological and technical purposes. They are influence on movement, storage and availability of water and nutrients for plants, ease of plant root penetration and movement of heat and air. Furthermore, they are also effect chemical and biological properties of soil. Although Fluvisols (alluvial-meadow soils) are one of the most widespread soils in Serbia, little research has been done on them. The aim of this study was therefore to evaluate the most important physical properties of long-term irrigated Fluvisols that were formed on the carbonate deposit of the White Drim River in Kosovo and Metohija (Serbia). Eight profiles, i.e. 23 undisturbed soil samples and 69 disturbed soil samples were examined. The depth of the upper part of the soil profile, which lies above the layer of sand, stones and gravel, in which the roots of the plants develop, is very uneven from profile to profile, i.e. it varies from small (approx. 30 cm) to very large (>200 cm). The investigated Fluvisols are heavy textured (>50% clay content). The results show a high variability of the physical properties in the surface layer of these soils. Most of the investigated physical properties of the eight open Fluvisol profiles, in addition to the heavy texture, are quite favorable and fairly uniform in the plow layer, while they are much less favorable, though not particularly unfavorable, under the plow layer in deeper profiles.

AB  - Soil water deficit has an adverse effect on crop productivity and is one of the main limiting factors of global food security. Field experiments were conducted in Vojvodina, Serbia, to expand and improve knowledge about the effects of different levels of irrigation on maize grain yield and quality. The studied irrigation treatments were: full irrigation (I-100), 75% (I-75) and 50% (I-50) of I-100, and no irrigation (I-0)-rainfed. The irrigation level affects maize grain yield; protein, starch, and oil content; and mineral composition. The results show that that yield decreases with increasing water deficit in three study years. On average, full irrigation results in the highest oil content and rainfed conditions in the lowest. The starch content increases and the oil content decreases with decreasing irrigation. Irrigation significantly increases the concentrations of K, Mg, Fe, Mn, and Zn, and reduces the Ca concentration compared to the rainfed treatment. A 25% water deficit (I-75) has a positive effect on certain maize grain nutrients and the yield is significantly reduced. The highest grain yield and oil content are achievable with full irrigation. For good nutrientional quality of maize, treatment I-75 can be proposed under similar soil and climate conditions.

AB  - Surface soil hydrological properties like water infiltration and hydraulic conductivity have important
consequences for hydrological properties of soils in river basins and their knowledge is needed for
sound land management, as well as flood risk prevention. They are very dynamic properties due to
varying land use management practices. The objective of this study was to evaluate the effects of two land uses (native meadow and arable) on surface (0–30 cm) infiltration characteristics of a silty clay loam and sandy loam soils at three sites in the Kolubara river valley and the Nišava river valley, respectivelly, with temperate climate, Serbia. A site consisted of two adjacent but different land uses on the same soil types. For each land use, water infiltration rates were measured in triplicate using double ring infiltrometer. Particle size distribution, bulk density and soil organic matter content of the surface soil were determined. Experimental measurements in the field indicated that treatments significantly influenced water infiltration characteristics on both locations. At both site the infiltration rates showed a decrease as a function of elapsed time. Steady state infiltration rate and cumulative infiltration of sandy loam-textured soils under the meadows were much lower than that for the arable soils. By contrast, the infiltration capacity and cumulative infiltration of silty clay loam soils under the meadows was significantly (P < 0.05) higher compared to arable soils. Increase in infiltration capacity of arable soils were related to decrease in bulk density. In addition, in tilled sandy loam soil infiltration was much higher than in silty clay loam soil. However, infiltration in a silty clay loam under meadow was lower compared with sandy loam soil. According to the results of our study it could be concluded that the land use change infiltration properties of surface soil and consequently may alter the water balance of the area by
changing the amount of surface runoff and soil water retention. Knowledge of how management
practices affect infiltration capacity can aid growers in reducing soil quality and degradation.

AB  - The goal of this research is to determine the effects of different levels of water deficit (I100: full irrigation, I65: 35% deficit, I40: 60% deficit and I0: no irrigation) on yield and chemical composition of soybean [Glycine max (L.) Merr.] grown in Srem region of Serbia. Water deficit significantly affected the yield and chemical composition of soybean seeds. The lowest (1.63 t/ha) and the highest (3.21 t/ha) seed yields were obtained from I0 and I65 treatments, respectively. Furthermore, the highest protein (1092 kg/ha) and oil (563 kg/ha) yields were observed in I65 treatment. Lower and higher irrigation levels from I65 decreased the protein and oil yields. Our data indicated that irrigation generally increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. It was clearly observed that full-watered treatment (I100) provided no potential benefit in terms of soybean yield and chemical composition. For higher economic yield and good nutritional quality, water-saving treatment I65 could be suitable in soybean management in Srem region of Serbia as in other regions with similar soil and climate conditions.
AB  - Cilj ovog istraživanja bio je da utvrdi uticaj različitih nivoa deficita vode (I100: puno navodnjavanje, I65: 35% deficita, I40: 60% deficita i I0: bez navodnjavanja) na prinos i hemijski sastav soje [Glycine max (L.) Merr.] gajene u Sremu, Srbija. Deficit vode značajno je uticao na prinos i hemijski sastav zrna soje. Najmanji (1,63 t/ha) prinos zrna ostvaren je u tretmanu bez navodnjavanja (I0), a najveći (3,21 t/ha) na tretmanu I65. Pored toga, najviši prinosi proteina (1092 kg/ha) i ulja (563 kg/ha) ostvareni su u tretmanu I65. Niži i viši nivoi navodnjavanja od I65 smanjili su prinose proteina i ulja. Naši podaci pokazuju da navodnjavanje uglavnom povećava sadržaj K, P, Mg, Mn, Cu, Zn i B, a smanjuje sadržaj Ca i Fe u zrnu soje. Utvrđeno je da tretman punog zalivanja (I100) ne predstavlja potencijalnu korist u smislu povećanja prinosa i poboljšanja hemijskog sastava zrna soje. Za postizanje visokih ekonomskih prinosa i dobrog hemijskog kvaliteta zrna, tretman I65 može biti pogodan za gajenje soje na području Srema kao i u drugim područjima sa sličnim zemljišnim i klimatskim uslovima.

abstract = "The goal of this research is to determine the effects of different levels of water deficit (I100: full irrigation, I65: 35% deficit, I40: 60% deficit and I0: no irrigation) on yield and chemical composition of soybean [Glycine max (L.) Merr.] grown in Srem region of Serbia. Water deficit significantly affected the yield and chemical composition of soybean seeds. The lowest (1.63 t/ha) and the highest (3.21 t/ha) seed yields were obtained from I0 and I65 treatments, respectively. Furthermore, the highest protein (1092 kg/ha) and oil (563 kg/ha) yields were observed in I65 treatment. Lower and higher irrigation levels from I65 decreased the protein and oil yields. Our data indicated that irrigation generally increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. It was clearly observed that full-watered treatment (I100) provided no potential benefit in terms of soybean yield and chemical composition. For higher economic yield and good nutritional quality, water-saving treatment I65 could be suitable in soybean management in Srem region of Serbia as in other regions with similar soil and climate conditions., Cilj ovog istraživanja bio je da utvrdi uticaj različitih nivoa deficita vode (I100: puno navodnjavanje, I65: 35% deficita, I40: 60% deficita i I0: bez navodnjavanja) na prinos i hemijski sastav soje [Glycine max (L.) Merr.] gajene u Sremu, Srbija. Deficit vode značajno je uticao na prinos i hemijski sastav zrna soje. Najmanji (1,63 t/ha) prinos zrna ostvaren je u tretmanu bez navodnjavanja (I0), a najveći (3,21 t/ha) na tretmanu I65. Pored toga, najviši prinosi proteina (1092 kg/ha) i ulja (563 kg/ha) ostvareni su u tretmanu I65. Niži i viši nivoi navodnjavanja od I65 smanjili su prinose proteina i ulja. Naši podaci pokazuju da navodnjavanje uglavnom povećava sadržaj K, P, Mg, Mn, Cu, Zn i B, a smanjuje sadržaj Ca i Fe u zrnu soje. Utvrđeno je da tretman punog zalivanja (I100) ne predstavlja potencijalnu korist u smislu povećanja prinosa i poboljšanja hemijskog sastava zrna soje. Za postizanje visokih ekonomskih prinosa i dobrog hemijskog kvaliteta zrna, tretman I65 može biti pogodan za gajenje soje na području Srema kao i u drugim područjima sa sličnim zemljišnim i klimatskim uslovima.",

AB  - The goal of the present research is to determine an effective sprinkler irrigation strategy for soybean [Glycine max (L.) Merr.] in temperate climate conditions, in order to maximize yields and seed quality. A three-year field experiment with four different irrigation treatments was conducted on Calcic Chernozem in the Vojvodina region of Serbia. The irrigation regimes included: no irrigation; full irrigation (I-100); and two deficit irrigation treatments - 65% of I-100 (I-65) and 40% of I-100. The irrigation treatments generally had a statistically significant effect on the increase of soybean yield and protein content. Irrigation did not have a significant effect on the oil content. In general, irrigation increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. The results show that irrigation with the largest amount of water (treatment I-100) provided no potential benefit in terms of soybean yield and chemical composition. Treatment I-65, which exhibited the most favourable watering conditions, is the best choice to maximize yield and ensure a good chemical composition of soybean under these agroecological conditions.

AB  - Conversion of meadow and forest ecosystems to agricultural land generally leads to changes in soil structure. This comparative study presents the composition and stability of structural aggregates in humus horizons (0-30 cm) of noncarbonate silty-clay Fluvisols in the Kolubara River Valley, W Serbia. Aggregates collected from under a native forest were compared to aggregates from meadows and arable fields which underwent crop rotation for > 100 y. The results show that size distribution and stability of structural aggregates in the humus horizons of arable soil are significantly impaired due to long-term anthropogenization. In the humus horizons, the content of the agronomically most valuable aggregates (0.25-10 mm) decreased by a factor of approximate to 2, from 68%-74% to 37%-39%, while the percentage of cloddy aggregates (>10 mm) increased by a factor of approximate to 2, from 23%-31% to 48%-62%, compared to forest aggregates The long-term-arable soil had significantly (p  lt  0.05) lower aggregate stability, determined by wet sieving, than meadow and forest soils The lowest aggregate stability was found in aggregates > 3 mm. Their content is approximate to 2.5-3 times lower in arable soil (13%-16%) than in forest soil (32%-42%) at a depth of 0-20 cm. The largest mean weight diameters of dry aggregates (dMWD) with a range between 12.6 and 14 7 mm were found in arable soil, vs. 95-9 9 mm in meadow and 6 5-8.3 mm in forest. The arable soil had significantly lower mean weight diameters of wet-stable aggregates (wMWD) and a lower structure coefficient (Ks) than forest and meadow soils The dispersion ratio (DR) of arable soil was significantly higher than that of forest and meadow soils. Forest and meadow showed a significantly higher soil organic-matter content (SOM) by 74% and 39%, respectively, compared with arable soil, while meadow uses decreased the SOM content by 57% compared with forest at a depth of 0-10 cm In conclusion, the results showed that long-term conventional tillage of soils from natural forest and meadow in the lowland ecosystems of W Serbia degraded soil aggregate-size distribution and stability and reduced SOM content, probably resulting in lower productivity and reduced crop yields

AB  - The objective of this study was to measure and compare soil-water infiltration, soil water retention and bulk density at three soil depths of non-carbonate silty clay gleyic fluvisol in the Kolubara river valley (West Serbia) under natural deciduous forest and meadow vegetation and the adjacent gleyic fluvisol used for more than 100 years as cultivated soil, with the same site conditions. Five infiltration measurement were made in each of three treatments. The results showes that the forest soil has the highest steady infiltration rate. The infiltration rate for the forest was about 2.5 times higher compared with the meadow and about 6 times higher compared with the cultivated soil. The soil water content for a selected pressure was the highest in the forest soil in the 0-15 cm depth compared with the meadow and cultivated soils. The meadow and cultivated soils did not show any significant (P  lt  0.05) difference in soil water content at the 0.0, -33 and -1500 kPa pressure. Results show that the forest soil can accept and store more available water than meadow and cultivated soils in the 0-30 cm depth.

AB  - The objective of this investigation was aimed to study the mineral composition of soils developed on dacito-andesite and their volcanic tuffs from Radocelo and Takovo and zeolitised andesite tuffs in village Igros in Zupa-Aleksandrovac. A selection of samples was collected from the area designated as Eutric Cambisol (Gajnjaca), Brown Forest and Brown Soils on the pedological maps. After collection the samples were air-dried and sieved to pass a 2 mm sieve and were used for further analyses. Soil reaction was determined in water as well as in 1M KC1 and in 1M NaF suspensions. Selective dissolution of Al, Fe and Si in non-crystalline materials was performed as follows: acid ammonium oxalate and sodium pyrophophate, as well as phosphate retention, determined according to BLACKMORE et al. (1987). The minerals in soil samples were studied by a combination of methods. The mineralogy of bulk soil samples was obtained by polarized microscopy and X-ray diffraction analysis (XRD). Minerals of clay fraction were also characterized by infrared spectroscopy and the XRD analysis. The XRD analyses were made on the clays  lt 2 μm specimens, as follows: air dried, ethylene glycol solvated, and progressively heated at 300°C and 500°C. Mineral composition of fresh volcanic rock is as follows: feldspars, zoned plagioclase, hornblende, pyroxenes and biotite, which are found either as phenocrysts or cryptocrystals in groundmass, in association of minor to traces of tourmaline, sphene, apatite and ore minerals. All ferromagnesian minerals are altered in various degrees to chlorite and clay minerals. Groundmass comprises of feldspar microlites in dark-grey volcanic glass and minor amounts of other minerals. The clay fraction of soils is composed mainly of halloysite/kaolinite, illite, chlorite, feldspars, and zeolite and poorly-ordered mineral-allophane and CT-opal. Only in the clay fraction from soil developed on a layer of zeolitised andesite tephra in Igros, heulandite-clinoptilolite-mordenite type zeolite was found as dominant resistant mineral associated with minor amounts of smectite and halloysite. Phosphate retention varies between 23.0 and 48.5% and the oxalate exchangeable active Alox + 1/2 Feox component varies between 0.50 and 1.58 as well as presence of the volcanic glass and about 9 to 11% of allpohane in the Bt horizon of the soils investigated have pointed to vitric-andosol type, with a lot of skeletal material.
AB  - Andosoli predstavljaju poseban tip u klasifikaciji zemljišta. Obrazuju se na vulkanskim stenama i njihovim tufovima. U cilju poznavanja mineralnog sastava zemljišta, razvijenog na andezitimna i njegovim tufovima, na području Radočela, na području kod sela Igroš (Aleksandrovačka Župa) i na području kod Takova, prikazane su njihove najbitnije karakteristike. Dacito-andazitski i labrador andazitski tufovi na planini Radočelo i kod Takova sastavljeni su od krupnih odlomaka kristala feldspata: sanidina, zonarnih plagioklasa sa 20-45% anortita, zatim biotita, muskovita, hornblende i retkih kristala augita, koji se pojavljuju kao fenokristali. Kao sastojci osnovne mase javljaju se turmalin, sfen, apatit i cirkon, kao i retki metalični minerali (magnetit i ilmenit). Kvarc se pojavljuje manjim količinama, kao sitna korodovane individua. Osnovna masa izgrađena je od mikrolita feldspata, vulkanskog stakla i ređe amfibola. Zemljišta sadrže značajne količine vulkanskog tufa kao skeleta u raznim fazama površinskog raspadanja. Frakcija gline sadrži mešavinu kaolinita i halojzita, ilita, i manjih količina smektita i mešovito slojevitih silikata po tipu ilit - smektit kao i tragova feldspata, getita i amfibola. Zemljište na Radočelu sadrži još i: kristobalit (0.405 nm), tridimit (0.411 nm) i opal, koji je zapažen po difuznom difrakcionom piku sa maksimumom oko 0.41 nm, što je indikativno je za CT - opal, neuređen i nisko temperaturni silicijski hidroksid, koji se nalazu u vulkanskim tufovima. Mineralni sastav zemljišta iz atara sela Igroš (Aleksandrovačka Župa), je drugačiji jer je matični supstrat zeolitisani tuf. Zeolitisani tuf se sastoji od devitrifikovanog vulkanskog stakla koje pokazuje različite stadijume zeolitizacije. Zeolit je iz grupe heilandit-klinoptilolit (Ca-Na zeoliti). U sastav tufa ulaze još feldspati i kvarc, praćeni manjim količinama hornblende, piroksena i biotita, zatim apatit i opake minerale. Zemljišta pokazuju distrični karakter, umereno ili slabo kiselu reakciju. Reakcija zemljišta u KC1 generalno je za čitavu jedinicu niža nego pH u vodi. Reakcija zemljišta u NaF je bila 10.07 do 10.71, odnosno značajno veća od 9.5 u dubljim horizontima, što je indikativno za andični material. Retencija fosfata je važan dijagnostički kriterijum za vitrične-andosole. Ispitivana zemljišta su pokazala varijaciju u retenciji fosfata između 23 i 48.5% što ih svrstava u vitrični-andosol. Sadržaj Alox + 1/2 Feox varira između 0.50 do 1.58 % što potvrđuje prethodne rezultate i ukazuje na vitrični-andosol sa tendencijom ka tipičnim andosolima na Radočelu. Nešto niže retencije fosfata mogu biti posledica intenzivnog đubrenja jer se parcele-njive koriste za poljoprivrednu proizvodnju. Sadržaj Siox varira između 0.17 to 1.46 %, pa zemljišta u Bt horizontu sadrže od 1.3 do 11.0% alofana. Prisustvo značajnih količina kaolinita/halojzita, kao i alofana (11.%), zatim vulkanskog stakla (15-20%), tipična asocijacija minerala u frakciji  lt  2 mm, indikativno je za zemljišta tipa vitrični-andosol, koja su nastala na starim izlivima neutralnih i bazičnih stena.

Phosphate retention varies between 23.0 and 48.5% and the oxalate exchangeable active Alox + 1/2 Feox component varies between 0.50 and 1.58 as well as presence of the volcanic glass and about 9 to 11% of allpohane in the Bt horizon of the soils investigated have pointed to vitric-andosol type, with a lot of skeletal material., Andosoli predstavljaju poseban tip u klasifikaciji zemljišta. Obrazuju se na vulkanskim stenama i njihovim tufovima. U cilju poznavanja mineralnog sastava zemljišta, razvijenog na andezitimna i njegovim tufovima, na području Radočela, na području kod sela Igroš (Aleksandrovačka Župa) i na području kod Takova, prikazane su njihove najbitnije karakteristike. Dacito-andazitski i labrador andazitski tufovi na planini Radočelo i kod Takova sastavljeni su od krupnih odlomaka kristala feldspata: sanidina, zonarnih plagioklasa sa 20-45% anortita, zatim biotita, muskovita, hornblende i retkih kristala augita, koji se pojavljuju kao fenokristali. Kao sastojci osnovne mase javljaju se turmalin, sfen, apatit i cirkon, kao i retki metalični minerali (magnetit i ilmenit). Kvarc se pojavljuje manjim količinama, kao sitna korodovane individua. Osnovna masa izgrađena je od mikrolita feldspata, vulkanskog stakla i ređe amfibola. Zemljišta sadrže značajne količine vulkanskog tufa kao skeleta u raznim fazama površinskog raspadanja. Frakcija gline sadrži mešavinu kaolinita i halojzita, ilita, i manjih količina smektita i mešovito slojevitih silikata po tipu ilit - smektit kao i tragova feldspata, getita i amfibola. Zemljište na Radočelu sadrži još i: kristobalit (0.405 nm), tridimit (0.411 nm) i opal, koji je zapažen po difuznom difrakcionom piku sa maksimumom oko 0.41 nm, što je indikativno je za CT - opal, neuređen i nisko temperaturni silicijski hidroksid, koji se nalazu u vulkanskim tufovima. Mineralni sastav zemljišta iz atara sela Igroš (Aleksandrovačka Župa), je drugačiji jer je matični supstrat zeolitisani tuf. Zeolitisani tuf se sastoji od devitrifikovanog vulkanskog stakla koje pokazuje različite stadijume zeolitizacije. Zeolit je iz grupe heilandit-klinoptilolit (Ca-Na zeoliti). U sastav tufa ulaze još feldspati i kvarc, praćeni manjim količinama hornblende, piroksena i biotita, zatim apatit i opake minerale. Zemljišta pokazuju distrični karakter, umereno ili slabo kiselu reakciju. Reakcija zemljišta u KC1 generalno je za čitavu jedinicu niža nego pH u vodi. Reakcija zemljišta u NaF je bila 10.07 do 10.71, odnosno značajno veća od 9.5 u dubljim horizontima, što je indikativno za andični material. Retencija fosfata je važan dijagnostički kriterijum za vitrične-andosole. Ispitivana zemljišta su pokazala varijaciju u retenciji fosfata između 23 i 48.5% što ih svrstava u vitrični-andosol. Sadržaj Alox + 1/2 Feox varira između 0.50 do 1.58 % što potvrđuje prethodne rezultate i ukazuje na vitrični-andosol sa tendencijom ka tipičnim andosolima na Radočelu. Nešto niže retencije fosfata mogu biti posledica intenzivnog đubrenja jer se parcele-njive koriste za poljoprivrednu proizvodnju. Sadržaj Siox varira između 0.17 to 1.46 %, pa zemljišta u Bt horizontu sadrže od 1.3 do 11.0% alofana. Prisustvo značajnih količina kaolinita/halojzita, kao i alofana (11.%), zatim vulkanskog stakla (15-20%), tipična asocijacija minerala u frakciji  lt  2 mm, indikativno je za zemljišta tipa vitrični-andosol, koja su nastala na starim izlivima neutralnih i bazičnih stena.",

AB  - An on-farm field experiment was conducted to investigate the effects of lime application on chemical composition, leaf stem ratio, stem height and herbage yield in dryland alfalfa during a three-year period. The soil of the experiment site was silty-loam, pseudogley (Stagnosols). The experiment was conducted in a randomized complete block design with three rates of ground limestone (0, 3 and 6 t ha(-1)). Lime application has a significant beneficial impact on herbage yield, crude protein content, stein height and leaf to stein ratio of alfalfa. Increasing amounts of lime had a significant effect on the concentration of nutrient elements in dried herbage of alfalfa. Lime applications significantly increased soil pH and improved the bioavailability of P, K Ca and Mg in the treated soil. Liming significantly reduced the Fe, Al, Mn, Zn and Cu contents in the soil.

AB  - In order to estimate the aggregate composition of carbonate loamy chernozems on the loess of South Banat, utilized as cultivated and pasture, fractionation was performed of individual categories of structural aggregates according to their size and also the determination of structure coefficient, mean weight diameter and geometric mean diameter of the dry structural aggregates. Laboratory analyses involved soil samples of the humus, i.e. arable (0-20-30 cm) and subarable horizons (20-40 and 40-60 cm) from 24 profiles of cultivated land and the samples of surface (0-20-30 cm) and subsurface layers (20-40 and 40-60 cm) of the humus horizons of 4 pasture profiles. The results of the investigations showed that beside favorable, mainly crumby-beady structure there appeared also significant differences in aggregate composition, both between various profiles, in dependence on the utilization mode of the soil, and between various depth zones of the humus horizon. The content of agronomical most valuable aggregates fraction (0.25-10 mm) in all depth zones of the humus horizon of the investigated profiles is >60%, which is, according to the classification by ŠEIN et al. (2001), a characteristic of good-structured soil. According to the values of structure coefficient and the mentioned classification, the cultivated soil profiles (1.5-2.42) show good, and those from pasture (1.15-1.70) satisfactory structure. In cultivated soil profiles, mean weight diameter and geometric mean diameter of the dry aggregates is significantly higher than in those from the pasture, and when they are larger, the structure of the soil is better and vice versa. .
AB  - U cilju ocene agregatnog sastava karbonatnih ilovastih černozema na lesu Južnog Banata, pri njivskom i pašnjačkom načinu korišćenja, izvršeno je frakcionisanje pojedinih kategorija strukturnih agregata prema njihovoj veličini i određivanje koeficijenta strukturnosti, srednjeg masenog i srednjeg geometrijskog dijametra strukturnih agregata. Laboratorijskim analizama obuhvaćeni su zemljišni uzorci humusnog, odnosno oraničnog (0-20-30 cm) i podoraničnog horizonta (20-40 i 40-60 cm) iz 24 njivska profila i uzorci površinske (0-20-30 cm) i podpovršinskih proba (20-40 i 40-60 cm) humusnog horizonta iz 4 pašnjačka profila. Rezultati istraživanja pokazali su da pored povoljne, pretežno mrvičasto-graškaste strukture postoje i znatne razlike u agregatnom sastavu kako među raznim profilima, u zavisnosti od načina korišćenja zemljišta, tako i u raznim dubinskim zonama humusnog horizonta. Sadržaj agronomski najpovoljnijih agregata (0.5-10 mm) u svim dubinskim zonama humusnog horizonta istraženih profila je > 60%, što je, prema klasifikaciji Šein-a et al.

AB  - The paper examines the effects of lime application at the rate of 3 t/ha on pseudogley soil agrochemical changes and alfalfa yield during a two-year period. The applied lime in combination with mineral fertilizers significantly decreased acidity in H20 (by 0.6 pH units) and in nKCl (by 0.81 pH units). At the same time, there was increase in phosphorus availability (from 6.2 mg/100g of soil, control, to 19.1 mg/100 g of soil, variant with lime) and soil base saturation percentage in the 0-30 cm arable horizon. The performed liming intensified organic matter mineralization, which caused decrease of humus content as well as of mobile Al and Fe content compared to control. Moderate liming improved pseudogley agrochemical properties, which was manifested by increased alfalfa yield. In the first study year 19.7 t/ha of forage and 5.7 t/ of hay, respectively, was produced in control variant, while 28.5 t/ha of forage and 8.2 t/ha of hay, respectively, was produced in a variant with liming. Even higher yield was achieved in the second year of alfalfa utilization (8.5 t/ha of forage and 2.2 t/ha of hay, respectively, was produced in control, and 71 t/ha of forage and 16.3 t/ha of hay, respectively, in a variant with liming). .
AB  - Loše agrofizičke, a naročito agrohemijske osobine pseudoglejnih zemljišta okoline Kraljeva su ograničavajući faktor za gajenje lucerke. Cilj ovih istraživanja je bio da se melirativnom đubrenjem zemljišta-primenom kalcifikacije poprave agrohemijska svojstva pseudogleja i povisi prinos zelene krme i sena lucerke. Rezultati ovih istraživanja pokazuju da se umerenom kalcifikacijom od 3 t/ha kreča može značajno smanjiti kiselost za 0,6 pH jedinica u r^O, i za 0,81 pH jedinicu u nKCl. Smanjenjem kiselosti povećana je pristupačnost fosfora (sa 6,2 mg/100g zemljišta, kontrola, na 19,1 mg/100g zemljišta varijanta sa primenom kreča) i povećan stepen zasićenosti zemljišta bazama u oraničnom horizontu od 0-30cm. Izvedena kalcifikacija pojačala je mineralizaciju organske materije što je uticalo na smanjenje sadržaja humusa, a takođe smanjenje i sadržaja mobilnog Al i Fe u odnosu na kontrolu varijantu. Popravljena agrohemijska svojstva pseudogleja doprinela su povećanju prinosa krme i sena lucerke.

abstract = "The paper examines the effects of lime application at the rate of 3 t/ha on pseudogley soil agrochemical changes and alfalfa yield during a two-year period. The applied lime in combination with mineral fertilizers significantly decreased acidity in H20 (by 0.6 pH units) and in nKCl (by 0.81 pH units). At the same time, there was increase in phosphorus availability (from 6.2 mg/100g of soil, control, to 19.1 mg/100 g of soil, variant with lime) and soil base saturation percentage in the 0-30 cm arable horizon. The performed liming intensified organic matter mineralization, which caused decrease of humus content as well as of mobile Al and Fe content compared to control. Moderate liming improved pseudogley agrochemical properties, which was manifested by increased alfalfa yield. In the first study year 19.7 t/ha of forage and 5.7 t/ of hay, respectively, was produced in control variant, while 28.5 t/ha of forage and 8.2 t/ha of hay, respectively, was produced in a variant with liming. Even higher yield was achieved in the second year of alfalfa utilization (8.5 t/ha of forage and 2.2 t/ha of hay, respectively, was produced in control, and 71 t/ha of forage and 16.3 t/ha of hay, respectively, in a variant with liming). ., Loše agrofizičke, a naročito agrohemijske osobine pseudoglejnih zemljišta okoline Kraljeva su ograničavajući faktor za gajenje lucerke. Cilj ovih istraživanja je bio da se melirativnom đubrenjem zemljišta-primenom kalcifikacije poprave agrohemijska svojstva pseudogleja i povisi prinos zelene krme i sena lucerke. Rezultati ovih istraživanja pokazuju da se umerenom kalcifikacijom od 3 t/ha kreča može značajno smanjiti kiselost za 0,6 pH jedinica u r^O, i za 0,81 pH jedinicu u nKCl. Smanjenjem kiselosti povećana je pristupačnost fosfora (sa 6,2 mg/100g zemljišta, kontrola, na 19,1 mg/100g zemljišta varijanta sa primenom kreča) i povećan stepen zasićenosti zemljišta bazama u oraničnom horizontu od 0-30cm. Izvedena kalcifikacija pojačala je mineralizaciju organske materije što je uticalo na smanjenje sadržaja humusa, a takođe smanjenje i sadržaja mobilnog Al i Fe u odnosu na kontrolu varijantu. Popravljena agrohemijska svojstva pseudogleja doprinela su povećanju prinosa krme i sena lucerke. U prvoj godini na kontrolnoj varijanti ostvaren je prinos krme od 19,7 t/ha, odnosno 5,7 t/ha sena, dok na varijanti sa primenom kreča 28,5 t/ha krme, odnosno 8,2 t/ha sena. To povećanje prinosa još je vise bilo izraženo u drugoj godini iskorišćavanja lucerke (kontrola 8,5 t/ha krme, odnosno 2,2 t/ha sena, a varijanta sa krečom 71,4 t/ha krme, odnosno 16,3 t/ha sena).",

AB  - This paper shows possibilities and ways of cutting potato tubers. In potato seed production, besides standard tuber size (28-55 mm), some part of yield is made of tubers large than 55 mm In ware potato production, when does not exist enough certified seed, or the aim is to gel a high yield of marketable tubers, is possible to use like seed tubers larger than 55 mm in a certain way. There are some questions about economical aspects of exploiting large size tubers for planting, and about relations between yield achieved by planting tuber parts or by planting whole tuber, one and the same size. During two-year study (2001-2002), we tried to find differences in potato crops when we sow whole tubers and when we sow their parts. For the research we choose potato variety Kondor, tuber size 55-65 mm, with evenly spaced 5-6 eye. The cutting was done one month before sowing, in three different ways (in two, three and four parts). That month was the pre-sprouting period. During that period tubers were kept in trays at temperature 16-180C and 85-90% of relative air moisture. The results showed that higher total and marketable yield (tubers heavier than 70 g) was achieved by cutting the tubers in two and three parts, comparing to sowing of whole tubers or cut in four parts.
AB  - U radu su proučavane mogućnosti i načini sečenja krtola krompira U proizvodnji semenskog krompira osim standardne veličine krtola (28-55 mm) dobijaju se i određene količine semenskog krompira frakcije veće od 55 mm. Zbog nedostatka dovoljne količine kvalitetnog deklarisanog semenskog materijala. u proizvodnji konzumnog krompira je moguće koristiti krupne krtole na određen način, naročito ako se ili dobiti što veći udeo krupnih krtola u prinosu. Postavlja se pitanje kako najbolje iskoristili za sadnju ovakve krtole. Posmatrano sa ekonomskog stanovišta nameće se pitanje opravdanosti sadnje krupnih krtola pri najboljim proizvodnim uslovima. Takođe je interesantan i odnos prinosa postignut od sečenih i celih krtola iste semenske frakcije. Dobijeni rezultati sečenih krtola frakcije iste krupnoće-Jakovljević i sar. (1965), pokazuju da je razlika u visini prinosa između pojedinih semenskih frakcija sečenih, znatno veća nego razlika pri sadnju celih krtola iste frakcije, što znači da sečene krtole jače reaguju na veličinu semenskih krtola za sadnje. Iz ovoga proizilazi da se u krupnijih semenskih frakcija pojavljuje manja razlika u korist celih krtola što znači da sečenje krtola ove frakcije može u izvesnim slučajevima biti opravdano. ako je reč samo o visini prinosa, jer je razlika u prinosu neznatna. Tokom 2001. i 2002. godine pokušali smo da utvrdimo da li i u kojoj meri postoje razlike u usevima krompira kada se sade cele krtole i kada se sade njihovi delovi. Za sečenje je odabrana sorta Kondor, frakcije 55-65 mm, koje imaju najmanje 5-6 pravilno raspoređenih okaca na krtoli. Krtole su sečene na tri načina mesec dana pred sadnju (uzdužno, na tri dela i na četiri dela), i do sadnje su ostavljene da formiraju klicu, na temperaturi 16-18°C pri relativnoj vlažnosti 85-90 %. Na osnovu rezultata može se zaključiti da se najbolji efekat u pogledu ukupnog i tržišnog prinosa (krtole veće od 40 mm) ostvaruje korišćenjem sečenja na polovinu i trećinu krtola u odnosu na sadnju celih krtola ili sečenjem na četvrtine.

AB  - Long-standing utilization of agricultural machines in agricultural production leads to a significant increase of compaction in noncarbonate, slightly smonitza - like meadow black soils, in the Kolubara river valley. A substantial increase of compaction in the investigated soils was found in arable and subarable horizons down to the depth of 30 cm. The compaction increase induced negative changes in other most important physical properties of soil, like the increase of bulk density and packing density of soil particles, and the decrease of total porosity, content of pores > 30 mm and void ratio.

Znatno povećanje zbijenosti u istraženim zemljištima utvrđeno je u oraničnom i podoraničnom horizontu do 30 cm dubine.

AB  - Gajić Boško, Dugalić Goran and Đurović Nevenka (2001): Agro physical, characteristics of leached soil (luvisol) from the area of mountain in massif Radočelo. - Zemljište i biljka, Vol. 50, No. 2, 97-104, Beograd. The subject of this paper is a number of the most important agro physical properties of two profiles of (not severely) leached soil, over a deep volcano tufaceous deposition, from the altitudes around 1300 m, recently ploughed, for a long time under meadows (and before that covered with beech and spruce forest) from the mountain massif Radočelo, where very high yields of good quality potatoes (up to 40 tha-1) are achieved with the application of advanced agro technical measures. On the basis of conducted field and laboratory investigations it has been found that the analyzed leached soil shows rather favorable agro physical characteristics for normal development of the grown crops. .
AB  - Predmet istraživanja ovog rada je niz najvažnijih agrofizičkih osobina (mehanički i agregatni sastav, vodo-otpornost strukturnih agregata, zapreminska i specifična masa, vodni kapaciteti, hidraulički konduktivitet, ukupna i diferencijalna poroznost i vazdušni kapacitet) dva profila (ne jako) lesiviranog zemljišta na dubokom vulkanskom rufoznom depozitu, iz visinskog pojasa oko 1300 m, nedavno razoranom, dugotrajno livadskom (pre toga obraslom šumom bukve i smrče) zemljištu planinskog masiva Radočela, na kojem se ostvaruju veoma visoki prinosi (i do 40 tha-1) visokokvalitetnog krompira. Ispitano zemljište poseduje prilično povoljne agrofizičke osobine. U Ahp i AhE horizontu, do dubine 50 cm, zemljište po mehaničkom sastavu spada u slabo skeletoidne lake glinuše, a u Bt horizontu, na dubini 50-90 cm, u veoma slabo skeletoidne lake glinuše. Pored ne suviše teškog (ni lakog) mehaničkog sastava do dubine 50 cm, medu povoljne agrofizičke karakteristike ovog zemljišta spadaju: velika ukupna i fiziološka (aktivna) dubina profila, prilično povoljno stanje poroznosti i njime uslovljena dobra propusnost za vodu, vazduh i korene biljaka ne samo u Ah i E, već i u Bt horizontu; visok retencioni (oko 320 mm) i kapacitet produktivne vlage (oko 170 mm) na dubini 0-70 cm, takođe prilično visok apsolutni vazdušni kapacitet (14-20 % vol.) do dubine oko 50 cm, a znatan i na dubini 50-70 cm (7 % vol.). Naročito treba istaći činjenicu daje ispitano zemljište veoma rastresito u humusno-orničnom horizontu, ali da nije jako zbijeno ni u prvom podorničnom (AhE), pa čak ni u Bt horizontu.
