Kirinyaga County is well suited to Soybeans, scoring 85/100 on ShambaIQ's soil-match model. Local soils average pH 5.31 — moderately acidic and inside the 5–7 band Soybeans prefers, so no lime is usually required. Nitrogen (1.36 g/kg), phosphorus (12.5 mg/kg) and potassium (177 mg/kg) all meet Soybeans's requirements, so a maintenance fertilizer programme is enough. Soybeans prefers loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 75/kg) and a typical 700 kg/acre yield, a well-managed Soybeans crop here can gross roughly KES 52,500 per acre.
