Influence of crop residues as liming resources on change soil ph and phosphorous availability in acid soils

Abstract

An experiment was conducted on acid soils of Ranchi, India, to evaluate the effect of crop residues maize (Zea mays), wheat (Triticum aestivum), rice (Oryza sativa) and soybean (Glycin max) as a liming material in acid soil. In the present investigation four crop residues were arranged in completely randomized design (CRD). The results of study indicated that incorporation of crop residues was significantly increase soil reaction (soil pH) during all incubation days than the control treatments. The addition of maize, rice, wheat and soybean crop residues significantly (P
