Maintaining soil reaction at pH 7.0 is likely to virtually eliminate any significant _______ by heavy metals applied to soils with sewage sludge.
A)plant uptake
B)leaching
C)adsorption
D)precipitation
E)A and B

Question

Quizplus · Accepted Answer

Maintaining soil at a neutral pH (pH 7.0) can significantly reduce the plant uptake and leaching of heavy metals from soils treated with sewage sludge. At this pH, many heavy metals form insoluble compounds or bind to soil particles, reducing their mobility and bioavailability.
