dc.description.abstractIn 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.en
dc.description.abstractU 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.sr
