Distribution of Chemical Pools of Soil Zinc under Various Land Use Systems

Effects of ZnSO4 and Zn‐EDTA applied by broadcasting or by banding on soil Zn fractions and Zn uptake by wheat (Triticum aestivum L.) under greenhouse conditions

“…d, f). These two Zn fractions can be slowly released into the available Zn pool, replenishing the available Zn that is depleted due to wheat absorption ( Ramzan et al, ). In comparison, ZnSO 4 banded in soil produced a lower grain Zn concentration than ZnSO 4 broadcast in soil (Tab.…”

Status of Zinc Fractions in Soils of Cooch Behar District, West Bengal, India

“…Among the different zinc fractions, pH showed negative and lowest correlation with exchangeable zinc at 0-20 and 20-40 cm soil layers. This might be due to the fact that at higher pH, the formation of insoluble calcium zincate or higher oxides of zinc reduces the solution concentration 21 . Hence, it can be concluded that the chemical distribution of zinc pools in soils is in the order amorphous iron oxide-bound zinc > crystalline oxide-bound zinc > manganese oxide-bound zinc > organic matter-bound zinc > exchangeable zinc at both soil-depths, i.e.…”
