Growing Beans in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Yes — Nyandarua is well suited to Beans. Nyandarua's soil (pH 5.38, strongly acidic) gives Beans a suitability score of 76/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Nyandarua County is well suited to Beans, scoring 76/100 on ShambaIQ's soil-match model. At an average pH of 5.38 the soil is moderately acidic, below Beans's preferred 6–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Beans's requirements, so a maintenance fertilizer programme is enough. Beans prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Beans is the #16 soil match of the 106 crops we assess for Nyandarua County. At current prices (about KES 130/kg) and a typical 800 kg/acre yield, a well-managed Beans crop here can gross roughly KES 104,000 per acre.
