Agricultural sector in Kenya, contributes with 25% on GDP, yet this sector is far to supply adequate food for an increasing population due to declining soil productivity. Soybean (Glycine max L. Merrill) is relatively new crop being introduced in smallholders farming system in the Central Highlands of Kenya as source of nutrition, income generation and soil fertility improvement. However, the crop yields are below the national average. Soil acidity and depletion of nutrients affect negatively performance and yields of soybean in the region. The study was carried out for two seasons in Embu County to determine the effects of manure, lime and phosphorus (P) fertilizer on: (i) soil chemical properties and soybean yields; (ii) nitrogen (N) and phosphorus (P) uptake, and biological nitrogen fixation (BNF) by soybean; (iii) soil microbial biomass. The treatments included goat manure (0, 5 and 10 ton ha-1), lime (0 and 2 ton ha-1), and P fertilizer (0, 30 and 60 kg P2O5 ha-1). The experiment was laid out in a Randomized Complete Block Design (RCBD) with 4 replicates. Soils samples collected before and after the experiment were analyzed for soil chemical properties and microbial biomass (MB). Soybean N and P uptake, N fixation and yields were determined. Data generated was subjected to Analysis of Variance (ANOVA) and means were separated using Least Significant Difference (LSD) at 95% significance level (p
