Impact of bioSolid compost on sequestration and bioavailability of chromium in soils

摘要：

A plant growth experiment was conducted to study the impact of biosolid compost on growth of Indian mustard plants and on transformation of chromium in Tokomaru silt loam soil from Palmerston North, New Zealand. The results revealed that the shoot and root dry matter yields of mustard increased with increasing level of biosolid compost. Application of biosolid compost enhanced the reduction of Cr(VI) to Cr(III) and the subsequent retention of Cr in soil. Chromium toxicity in mustard was recorded beyond the 300mg (Cr)·kg<1> soil level.
