Growing Chilies in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Uasin Gishu County is a challenging environment for Chilies (soil-match score 30/100) and will need significant amendment before planting. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 6–7.5 band Chilies prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Chilies's requirements, so a maintenance fertilizer programme is enough. Chilies prefers sandy loam soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. At 2100 m, the county sits above Chilies's preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. Chilies's full potential is about 2,500 kg/acre (~KES 412,500/acre at KES 165/kg), but at Uasin Gishu's 30/100 suitability a realistic target here is closer to 938 kg/acre (~KES 154,770/acre) unless the constraints above are addressed.
