Abstract: An experiment was conducted on Alfisols of Ranchi, to assess the impact of crop residue as a liming material in acid soil. In the present investigation four crop residues maize (Zea mays), wheat (Triticum aestivum), rice (Oryza sativa) and soybean (Glycin max) were tested in completely randomized design. The incorporation of Zea mays, Oryza sativa, Triticum aestivum and Glycin max crop residues significantly (P<0.05) increased soil pH compared with the initial value and no significant difference was observed between the EC of initial value with residue amended soils. Incubating soils for longer period of time resulted in slight increase in soil pH as compared to control. Results revealed that incorporation of soybean and rice residues in Alfisol (acid soil) positively increase soil pH as compared to other residue treatment (maize and wheat residue) along with control.
