About the Cover

Soybean (Glycine max (L.) Merrill) is one of the most important legume crops being introduced into the smallholder farming systems of the Central Highlands of Kenya (CHK) to improve income and household nutrition of farmers. However, nutrient mining resulting from crop uptake and erosion; and soil acidity which affects plant nutrients less available through different means such as phosphorus fixation and impairment of biological mediated processes in the soil. The objective of the study was to evaluate the interactive effects of manure, lime and phosphorus fertilizer on soil chemical properties in an acid soil. The study consisted of 5 treatments: manure (0 and 5 ton.ha-1), lime (0 and 2 ton.ha-1) and P fertilizer (0 and 30 kg P2O5 ha-1). The experiment was laid out in a randomized complete block design (RCBD) with 4 replicates in plots of 4.0 m x 4.5 m.
