This study was carried out to evaluate chemical changes and corn growth in an Albaqualf soil.The tannery wastes used were primary sludge with Cr at the rates of 13.8 and 27.6Mgha-1 corresponding to 250 and 500mgkg-1 of Cr soil, respectively, and the sludge from liming, at the rates of 10.25 and 20.50Mgha-1. The experiment was conducted in a greenhouse during 108days.The liming sludge increased pH (4.9 to 5.8), soil Ca (0.5 to 3.2cmolcdm-3) and resulted in corn yields similar to […]
