Growing Chilies in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Vihiga County is a challenging environment for Chilies (soil-match score 33/100) and will need significant amendment before planting. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Chilies's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.02 g/kg), phosphorus (14.8 mg/kg) and potassium (164 mg/kg) all meet Chilies's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Chilies, which favours sandy loam. At 1700 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.
