 en Effect of Lime on Soil Properties, N Nutrition and Nutrient Uptake of Maize in Some Nigerian Soils
Adetunji, M.T & Bamiro, F.O.

Abstract

Incubation and pot experiments were conducted to evaluate changes in soil properties due to liming and to determine the interaction effect of lime and N addition on maize growth and nutrient uptake in some Nigerian soils. Soil CEC, exchangeable Ca2+, Olsen P, and available S increased significantly within the first 3 weeks of incubation while the exchangeable Mg2+ and K+ increased only slightly. Liming to pH 6.0 reduced Al3+ saturation to less than 5% and gave maximum nutrient uptake and dry matter yield. For every cmolc kg-1 of Al3+, 1.88g of lime kg-1 of soil was required to keep the pH and Al3+ saturation at optimum levels for efficient nutrient utilization by maize. The interaction between N and lime was positive and significant. However, lime addition had greater influence on P and S uptake than on N addition while N addition had greater influence on N and K uptake of maize.
