Growing Chilies in Murang'a

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

Chilies can be grown in Murang'a County, but the soil scores 47/100 and needs targeted management to reach full potential. At an average pH of 5.03 the soil is moderately acidic, below Chilies's preferred 6–7.5 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 Chilies's requirements, so a maintenance fertilizer programme is enough. Chilies prefers sandy loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. At 1500 m, the county sits above Chilies's preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 165/kg) and a typical 1,800 kg/acre yield, a well-managed Chilies crop here can gross roughly KES 297,000 per acre.
