Ultisols in Benue state were studied to determine the solution phosphate concentration (SPC) required to obtain optimum yield of soybean for estimating the P fertilizer requirement of soybean. Soil inorganic P was fractionated using standard procedures. Sorption characteristics were determined in 0.01 M CaCl 2 solutions of various P concentrations. Amounts of P that gave 0. 025, 0.05, 0.075, 0.100, 0.125, 0.150, 0.175, 0.200, 0.225, 0.250
Phosphorus (P) sorption influences P requirement of Nigerian soils. Four Inceptisols in Benue state were therefore used to examine the influence of soil properties on sorption indices and yield of soybean. Soil inorganic P was fractionated using standard procedures. Sorption characteristics were determined in 0.01 M CaCl 2 solutions of various P concentrations. For each soil, the amounts of P that gave 0
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
