Abstract:
|
Incubating soil with applied zinc decreased the uptake of zinc by subterranean clover and DTPA extractable zinc (ZnD) on all soils relative to freshly applied zinc. On soils where plant growth was increased by zinc application, prior incubation of the soil led to decreased plant growth responses to zinc. The extent of the decline in availability with incubation differed among soils being greater in alkaline soils, in soils with high clay contents, in soils with high levels of organic carbon and in soils w
