Growing Chilies in Nandi

Soil suitability analysis based on Nandi's nutrient profile

Nandi County is a challenging environment for Chilies (soil-match score 32/100) and will need significant amendment before planting. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–7.5 band Chilies prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Chilies's requirements, so a maintenance fertilizer programme is enough. Chilies prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. At 1900 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 Nandi's 32/100 suitability a realistic target here is closer to 1,000 kg/acre (~KES 165,000/acre) unless the constraints above are addressed.
