Growing Beans in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Murang'a County is a solid choice for Beans, with a soil-match score of 68/100. At an average pH of 5.03 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 (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Beans's requirements, so a maintenance fertilizer programme is enough. Beans prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. Beans's full potential is about 800 kg/acre (~KES 104,000/acre at KES 130/kg), but at Murang'a's 68/100 suitability a realistic target here is closer to 680 kg/acre (~KES 88,400/acre) unless the constraints above are addressed.
