Growing Beans in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a solid choice for Beans, with a soil-match score of 74/100. At an average pH of 5.31 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 (1.36 g/kg), phosphorus (12.5 mg/kg) and potassium (177 mg/kg) all meet Beans's requirements, so a maintenance fertilizer programme is enough. Beans prefers loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. 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.
