Abstract
Applying alkaline fly ash on sludge-amended soils was effective in reducing the uptake of Cd by sudangrass (Sorghum vulgare cv. Trudan) by as much as 87%. The most apparent beneficial effect of a fly ash-sludge joint application was the diminution of plant tissue Cd for plants grown in the acid soil. However, fly ash also induced levels of soil salinity sufficient to damage crops. By weathering the fly ash before soil incorporation, the yield-depressing salinity effect was overcome.This publication has 5 references indexed in Scilit:
