Abstract
SummaryThe influence of soil clay type on the ‘availability’ of zinc was studied in six rendzina soils from Israel. The quantities of zinc extracted by EDTA—(NH4)2CO3, were higher in the soils with a lower total of zinc content. Values of extracted zinc calculated on the basis of soil minus CaCO3 were higher in soils with attapulgite than in soils with montmorillonite as the predominant mineral. Thus, it appears that zinc is more strongly bound to montmorillonite. This was confirmed by a greenhouse experiment in which total zinc uptake after zinc fertilization was higher from rendzinas containing attapulgite than from montmorillonitic rendzinas.
