AB  - Investigations were performed on soils of different acidity, ranging in the pH interval 4.65-5.80 (in water). Changes of the mineral nitrogen forms in the examined soils were studied by applying short-term incubation experiments performed under aerobic conditions, with a humidity of 30 % and a temperature of 20°C, both with and without the addition of 100 and 300 ppm NH4-N. The results of the incubation experiments showed that retarded nitrification was present in all the examined soils. Increased and toxic quantities of nitrites (35.7 ppm) were formed during the incubation, which remained in the soil solution for several days, and even weeks, in spite of favorable conditions of moisture, aeration and temperature for the development of the process of chemoautotrophic nitrification. Decelerated chemoautotrophic nitrification was the source of the occurrence of nitrite in the examined less acid soil (soil 1), while in soils of higher acidity (soils 2 and 3) after addition of 100 and 300 ppm NH4-N, nitrite occurred due to chemical denitrification (chemodenitrification). Nitrites formed in the process of chemodenitrification underwent spontaneous chemical oxidation resulting in nitrate formation (chemical nitrification). The content of mineral nitrogen (NH4 + NO3 + NO2-N) decreased during the incubation period, proving gaseous losses from the examined soils. Application of lower doses of nitrogen fertilizers could decrease nitrogen losses by denitrification as well as the occurrence of nitrite in toxic quantities in the investigated pseudogley soil.
AB  - Istraživanja su obavljena na zemljištu tipa pseudoglej iz okoline Šapca. Ispitivana zemljišta spadaju u grupu kiselih i jako kiselih zemljišta. Promene mineralnih oblika azota su praćene pomoću kratkotrajnih inkubacionih ogleda (vlažnost 30 % i temperatura 20 °S), sa i bez dodatka 100 i 300 ppm NH4-N. Tokom inkubacije utvrđene su povišene i toksične količine nitrita, koje su se u zemljišnom rastvoru zadržavale više dana i nedelja. Utvrđene količine nitrita su se javljale kao posledica usporene biološke nitrifikacije (kod manje kiselog zemljišta), dok su pri dodatku 100 i 300 ppm NH4-N one nastajale u procesu hemodenitrifikacije. U ispitivanim zemljištima se odvijala i spontana oksidacija nastalih nitrita hemijskim putem (hemijska nitrifikacija). Da bi se smanjili gubici azota procesom denitrifikacije i stvaranje toksičnih količina nitrita na pseudoglejnom zemljištu se može preporučiti primena nižih doza azotnih đubriva u odnosu na doze koje se primenjuju kod neutralnih i alkalnih zemljišta.

AB  - An experimental field for the cultivated production of Gentiana lutea L. was established five years ago at the Suvobor Mountain, Serbia. Soil analysis of this area revealed the occurrence of high pseudo-total (Ni - 1270 mg/kg, Cr - 423 mg/kg, Co - 385 mg/kg) and available (especially Ni - 133 mg/kg) heavy metals contents in the soil. Hence, the aim of this research was to evaluate the quality of Gentiana lutea L. - roots and galenic forms (liquid extract in 70 % ethanol, spissum and siccum) produced from the roots, because, for most plants, heavy metals accumulate in the root tissue. The amounts of Ni and Cr found in the analyzed roots were very high (54 mg/kg and 14 mg/kg, respectively). The efficiency of ethanol in extracting heavy metals from the roots varied depending on the particular element. The highest efficiency was obtained for Ni (41.3 %), then for Cd (39.5 %), Pb (37.0%) and Co (30.4 %). According to this, a potential hazard exists for humans, if gentian's galenic forms are produced from the raw material with high heavy metals contents. It is concluded that quality control of the raw material must be carried out before further utilization of gentian.
AB  - Eksperimentalna stanica za proizvodnju gencijane (Gentiana lutea L.) zasnovana je na planini Suvobor (Srbija) pre pet godina. Analizom zemljišta sa te lokacije utvrđeni su povišeni pseudo-ukupni (Ni - 1270 mg/kg, Cr - 423 mg/kg, Co - 385 mg/kg) i pristupačni (posebno za Ni - 133 mg/kg) sadržaji teških metala. Stoga je cilj ovog rada bio evaluacija kvaliteta korena gencijane i galenskih proizvoda (tečni ekstrakt u 70 % etanolu, spissum i siccum) dobijenih iz korena, jer se kod većine biljaka teški metali akumuliraju u tkivu korena. U analiziranom korenu utvrđeni su vrlo visoki sadržaji Ni (54 mg/kg) i Cr (14 mg/kg). Efikasnost etanola u ekstrakciji teških metala iz korena varirala je u zavisnosti od elementa. Najveća efikasnost uvrđena je za Ni (41,3 %), zatim za Cd (39,5 %), Pb (37,0 %) i Co (30,4 %). Prema tome, postoji potencijalna opasnost za čoveka pri upotrebi galenskih proizvoda dobijenih iz sirovine sa visokim sadržajem teških metala. Zaključeno je da kontrola kvaliteta sirovinskog materijala mora da se sprovodi pre dalje upotrebe gencijane.

AB  - This research investigates the influence of inoculating wheat and sunflower seeds with mixed bacterial populations regarding microbial biomass of rizospheric soil as well as weat and sunflower yields. There have been used following bacterial population for inoculation Azotobacter chrooococcum Psl, Z-l S-07, S-13, Bacillus megaterium R-l, S-19 i Bacillus circulans V2, 0-21, taken from the collection of microorganisms from Department for soil and water management of Faculty of Agriculture in Belgrade. The experiment with wheat (specimen Pesma)has been settled at plots of experimental field of Faculty of Agriculture in Belgrade "Radmilovac", and the experiment with sunflower (hybrid NS-Hl 11) on the property of collective farm in Jermenovci. Inoculation of the wheat and sunflower with mixed populations resulted in bacterial biomass enhancement in their rizosphere as well as enhancement of bacterial biomass in total microbial biomass. The. added hamates had influence on bacterial survival in the rhizosphere. The sunflower yield had 10% enhancement and wheat 29-32% comparing to non inoculated sample. These results justify the application of biofertilization in modern agricultural production, when it is used in order to supply the plants with necessary nutrients and also to maintain healthy environment and safe food production.

AB  - The contents of adsorbed Ca and Mg and their ratio (Ca/Mg) were researched in the serpentinite rankers of Serbia. The samples were taken from seven wider locations (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor and Bubanj Potok) in the altitudinal belt between 100 and 1700 m. Altogether 32 soil profiles were opened and 47 soil samples were analyzed. The percentages of adsorbed Ca and Mg were determined by the method of the Atomic Absorption Spectrophotometry, after extraction with NH4-acetate. The study results show that the content of adsorbed Mg-ions in almost all analyzed samples was higher than the percentage of adsorbed Ca-ions, so their ratio (Ca/Mg) is less than 1. This Ca/Mg ratio has an unfavorable impact on the plant development and it was concluded that this is one of the basic reasons of the low productive capacity of the serpentinite rankers in Serbia.
AB  - U radu su prikazani rezultati istraživanja sadržaja adsorbovanog Ca i Mg kao i njihovog odnosa (Ca/Mg) u serpentinitskim rankerima Srbije. Uzorci su uzeti iz sedam širih lokacija (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor i Bubanj Potok) u visinskom pojasu između 100 i 1700 m nad.visine. Ukupno su otvorena 32 pedološka profila i analizirano je 47 uzoraka zemljišta. Sadržaj apsorbovanog Ča i Mg određen je metodom atomske aprsorpcione spektrofotometrije, posle ekstrakcije sa NH4-acetatom. Rezultati istraživanja su pokazali da je skoro u svim ispitanim uzorcima sadržaj apsorbovanog Mg-jona veći od sadržaja apsorbovanog Ca-jona, te je i njihov odnos (Ca/Mg) manji od jedinice. Ovakav odnos Ca/Mg se nepovoljno odražava na uspevanje biljaka i smatramo da je jedan od osnovnih uzroka niske produktivne sposobnosti serpentinitskih rankera Srbije.

AB  - The paper presents the study results of the content of mobile Ni in serpentine rankers of Serbia. The samples were taken from seven wider locations (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor and Bubanj Potok) in the altitudinal zone between 100 and 1700 m. Extraction of mobile Ni was conducted with 1.0 N HC1, and its contents were determined by the method of atomic absorption spectrophotometry. The results of analysis show that around 70% of the tested samples contain 200 - 600 mg/kg of mobile Ni, which is far above the admissible quantities for the total Ni in the soil. Therefore, the serpentine rankers of Serbia contain phytotoxic concentrations of mobile Ni, which is one of the main reasons of poor growth of plants on these rankers.
AB  - U radu su prikazani rezultati istraživanja sadržaja mobilnog Ni u serpentintskim rankerima Srbije. Uzorci su uzeti sa sedam širih lokacija (Zlatibor, Kopaonik, Miroč, Maljen, Bukovi, Suvobor i Bubanj Potok) u visinskom pojasu između 100 i 1700 m nad.visine. Ekstrakcija mobilnog Ni izvršena je sa 1.0 N HCl, a njegov sadržaj određen metodom atomske apsorpcione spektrofotometrije. Rezultati analiza pokazuju da oko 70% ispitanih uzoraka sadrži 200 - 600 mg/kg mobilnog Ni, što je mnogo vise od dozvoljenih količina koje se daju za ukupni Ni u zemljištu. Prema tome, serpentintski rankeri Srbije sadrže fitotoksične koncentracije mobilnog Ni, što je jedan od bitnih razloga lošeg uspevanja biljaka na njima.

AB  - In this paper results are presented of agrochemical and mineralogical analyses of 14 types of important soils in Serbia (Vojvodina and Central Serbia) and total content and availability of base alkali elements (Ca, Mg Na, K) are determined. Total element content was as follows: Ca 2.22%; K 1.77%; Na 0.85% and Mg 0.61%. Total content of alkali metals in the soils investigated and their variations within and between the soil types, is in very good/close correlation with contents of primary and secondary minerals as well as their rates of weathering. Taking in account the average availabilities the most abundant is calcium with 947 mg/100 g, whilst the averages of the other elements (Mg, K and Na) are quite similar and are about of 40 mg/100 g of soil. The results obtained have shown that the soils investigated are well to moderate provided with K, Ca and Mg and that their deficit could not be expected in plant nutrition, apart for some plants/cultures in the case of magnesium due to occasionally higher Ca/Mg and K/Mg ratios.
AB  - U ovom radu je ispitivano 100 reprezentativnih uzoraka 14 tipova zemljišta Srbije (Vojvodina, Šumadija i Severno Pomoravlje) u pogledu ukupnog i pristupačnog sadržaja osnovnih alkalnih metala (Ca, Mg, K i Na). Takođe je prikazan i prosečan mineraloški sastav ispitivanih zemljišta. Nađeni su sledeći srednji ukupni sadržaji ispitivanih elemenata: Ca - 2,25%; K - 1,77% Na - 0,85% i Mg - 0,61%. Ukupni sadržaji ispitivanih alkalnih metala u našim zemljištima i njihova vapipanja između i unutar zemljišnih tipova u uskoj su vezi sa zastupljenošću određenih primarnih i sekundarnih minerala i njihovom otpornošću na raspadanje. Prema srednjim vrednostima za pristupačne sadržaje najviše ima kalcijuma (947 mg/100 g), a srednji sadržaji za ostale baze (Mg K i Na) su vrlo slični i kreću ce oko 40 mg/100 g. Dobijeni rezultati pokazuju da su ispitivana zemljišta dobro i srednje obezbeđena K, Ca i Mg i da se ne mogu očekivati njihovi deficiti za ishranu biljaka, osim za neke kulture u slučaju magnezijuma, zbog ponekad suviše povišenih odnosa Ca/Mg i K/Mg.

AB  - The effects of trunk ringing in apple cvs Idared (on MM 106 rootstock) and Granny Smith (on M26 rootstock) were studied. The trees were ringed in spring, two-three weeks prior to flowering in the one year (variant Tl) or repeatedly - in two subsequent years (variant T2). Ringing did not affect the cropping potential in the year of treatment. Nevertheless, via more abundant flower bud initiations, it multiply increased the stated potential for the following year. Yields of the treated trees in the second year depended on the cultivar and the treatment, being for 2.8 up to 5.3 times higher as compared to the control. In terms of the trees which were ringed twice (T2), the indices of generative potential were somewhat higher as related to the variant Tl. However, the differences were not statistically significant. Ringing did not significantly affect the fruit quality - mass and chemical content.

AB  - The beneficial effect of soybean inoculation with bradyrhizobia is well known. The aim of this research was to determine the effect of inoculation of soybean seed with mixed population of Bradyrhizobium japonicum. Bacillus megaterium, Bacillus circulons, and Azotobacter chroococcum, on the number of microorganisms and yield of soybean. The experiment was conducted on chernozem at the experimental field of Maize Research Institute, Zemun Polje. Soybean seeds were inoculated before seeding. Bacterial mixture has contained equal amounts of the bacteria in the peat. Humate is added to peat in order to prolong bacteria survive. The control variant was inoculated with Bradyrhizobium japonicum. The study showed that seed inoculation with bacterial mixtures caused an increase in microbial activity in the soil rhizosphere (total bacterial number, number of ammonifiers, azotobacters and dehydrogenase).

The aim of this research was to determine the effect of inoculation of soybean seed with mixed population of Bradyrhizobium japonicum. Bacillus megaterium, Bacillus circulons, and Azotobacter chroococcum, on the number of microorganisms and yield of soybean. The experiment was conducted on chernozem at the experimental field of Maize Research Institute, Zemun Polje. Soybean seeds were inoculated before seeding. Bacterial mixture has contained equal amounts of the bacteria in the peat. Humate is added to peat in order to prolong bacteria survive. The control variant was inoculated with Bradyrhizobium japonicum. The study showed that seed inoculation with bacterial mixtures caused an increase in microbial activity in the soil rhizosphere (total bacterial number, number of ammonifiers, azotobacters and dehydrogenase). The highest yield of soybean was obtained by inoculation with B. japonicum, B. megaterium and Bacillus circulons (4.5tlha)., Povoljan efekat inokulacije soje kvržičnim bakterijama odavno je poznat.

AB  - The soils samples of typical simonitza soils were collected from the plough layers at 10 locations in Serbia. The basic physical and chemical properties, as well as, the total and available Cu content in the soil were determined. The availability of Cu was also evaluated through the pot experiment with oat as a test plant. The regular, geochemical levels of the total Cu were found in our smonitza soils (mean 33.35 ppm, range 17-74 ppm). The available Cu content, determined after the extraction with different reagents (0.1 N HCl, DTPA and acid solution of NaOAc), was in correlation with its total content in the soil. The extraction efficiency of Cu from the soil varied (15.8%, 13.2% and 3.5%) in respect to its total content. The concentration of Cu in oat plants was about 11 ppm, with very low variations. This, as well as the statistically insignificant correlation coefficient between absorbed Cu and its content in the soil, indicates that the investigated smonitzas are well supplied with available Cu.

AB  - Soil sampling was carried out in the Velika Morava river valley, covering the area from Velika Plana to the mouth of Morava to the Danube. The composite soil samples, representing alluvial soils (22 samples), cambisols (14) and smonitzas (4), were taken from plough layers, based on a regular square grid with intervals set at 5x5 km, covering total area of 100,000 ha. The total and available fluorine contents were determined in the soils samples. The highest average amount of total fluorine was found for alluvial soils (391 mg kg-1), then for smonitzas (348 mg kg-1) and the lowest one for cambisols (285 mg kg-1). These amounts are within normal fluorine content for soils (150-400 mg kg-1), although the maximum found levels were even about 500 mg kg-1. The available fluorine content was very low ( lt  1 mg kg-1), being mostly less than 0.2 % from its total amount, so it could be concluded that there was no danger from fluorine accumulation in the plants. Statistically significant correlation coefficient between total and available fluorine contents was not obtained. The total and available fluorine contents have mostly been in the correlation (with positive sign) with soil pH and the content of mechanical fraction silt+clay. Significant correlation coefficients between total fluorine content and the content of some heavy metals (Cr, Ni, Co, Cu, As) were also found, which indicated their mutual geochemical origin.

Za ukupni fluor najviše srednje vrednosti su nadjene u aluvijumima (391 ppm), zatim u smonicama (348 ppm) i najmanje u gajnjačama (285 ppm). Ove vrednosti se nalaze u granicama normalnih sadržaja za zemljišta (150-400 ppm), mada se maksimalne vrednosti kreću i oko 500 ppm. Pristupačni sadržaj fluora je u ispitivanim zemljištima jako nizak ( lt  1 ppm), što najčešće čini ispod 0,2 % od ukupnog fluora, pa se može zaključiti da ne postoji opasnost od akumulacije fluora u biljkama koje se gaje na ispitivanom području. Nije nadjena korelativna veza ukupnog sa pristupačnim fluorom.

AB  - Phosphogypsum is formed as a by-product in the process of 'green' phosphoric acid production. This is done in the so called 'wet process' by the action of sulphuric acid on raw phosphate at low temperature ( lt 100 °C). Despite the same molecular formula and marked similarity with natural gypsum, phosphogypsum contains more than 50 impurities, and this is directly connected with the type of phosphate used in the production cycle. The aim of this paper was to consider the possibility of using phosphogypsum for amelioration of solonetz soil, bearing in mind its content of heavy metals, which are rather toxic for human organism and which can be transferred from soil to various plants used in human nutrition. On the other hand, there are very few data in the literature about the determination of heavy metals in phosphogypsum. The content of heavy metals in phosphogypsum was determined by atomic absorption spectrophotometry because this method has broad application in ana­lytical practice due to its high sensitivity, selectivity and precision. The results of the investigation indicate the following average content of heavy metals (in ppm): Fe-785, Pb-45, Zn-45, Cd-7, Mn-8, Co-10, Ni-20 and Cu-17. For the investigation of the effect of phosphogypsum on solonetz soil the following points were taken into consideration: maximum recommended dose of phosphogypsum (7 t/ha) for the amelioration of solonetz soil and the weight of soil layer (from 0 to 20 cm) having an area of 1 ha. The results obtained indicate that the amounts of heavy metals that are introduced into the soil with 7 t/ha of phosphogypsum are in the range from 0.035 to 0.8% of their maximum permissible content for arable soils. This means that only long-term application of phosphogypsum would introduce significant amounts of these elements into the soil.
AB  - Procesom dobijanja 'zelene' fosforne kiseline tzv. 'mokrim postupkom', dejstvom sumporne kiseline na sirovi fosfat na niskoj temperaturi ( lt 100 °C) kao nus-proizvod nastaje - fosfogips (sa faktorom 5:1, u odnosu na H3PO4). Uprkos istoj molekulskoj formuli i izraženoj sličnosti sa prirodnim gipsom, fosfogips sadrži preko 50 vrsta nečistoća, što je u direktnoj vezi sa vrstom fosfata koji je korišćen u proizvodnom ciklusu. Cilj rada bio je razmatranje mogućnosti primene fosfogipsa za melioraciju soloneca, sa aspekta sadržaja teških metala, koji su izuzetno toksični i kumulativni za čovekov organizam, a iz zemljišta prelaze u biljke, kojima se čovek hrani. Sa druge strane, u literaturi se nalaze veoma oskudni podaci o ispitivanju sadržaja teških metala u fosfogipsu. Sadržaj teških metala u fosfogipsu određivan je metodom atomske apsorpcione spektrofotometrije (AAS), budući da je to metoda koja je našla veliku primenu u praksi usled visoke osetljivosti, selektivnosti i preciznosti. Rezultati ispitivanja su pokazali sledeći sadržaj teških metala (u ppm): Fe-785, Pb-45, Zn-45, Cd-7, Mn-8, Co-10, Ni-20, Cu-17. Za ispitivanje uticaja primene fosfogipsa za melioraciju soloneca, uzeta je u obzir preporučena maksimalna norma za gipsovanje soloneca od 7 t/ha zemljišta i težina sloja debljine od 0 do 20 cm a površine 1 ha. Dobijeni rezultati su pokazali da se preporučenom maksimalnom normom za gipsovanje soloneca fosfogipsom unosi po 1 ha zemljišta od 0,035 do 0,8% od maksimalno dozvoljenog sadržaja teških metala - MDK vrednosti, što znači da bi tek višegodišnjom upotrebom fosfogipsa došlo do unošenja značajnijih količina ovih elemenata u zemljište. Kako se proces melioracije soloneca najčešće vrši u intervalu od 5 do 6 godina, unošenje teških metala bilo bi u zanemarljivoj količini i bez uticaja na životnu sredinu.

Za ispitivanje uticaja primene fosfogipsa za melioraciju soloneca, uzeta je u obzir preporučena maksimalna norma za gipsovanje soloneca od 7 t/ha zemljišta i težina sloja debljine od 0 do 20 cm a površine 1 ha. Dobijeni rezultati su pokazali da se preporučenom maksimalnom normom za gipsovanje soloneca fosfogipsom unosi po 1 ha zemljišta od 0,035 do 0,8% od maksimalno dozvoljenog sadržaja teških metala - MDK vrednosti, što znači da bi tek višegodišnjom upotrebom fosfogipsa došlo do unošenja značajnijih količina ovih elemenata u zemljište. Kako se proces melioracije soloneca najčešće vrši u intervalu od 5 do 6 godina, unošenje teških metala bilo bi u zanemarljivoj količini i bez uticaja na životnu sredinu.",
