Growing Chilies in Meru

Soil suitability analysis based on Meru's nutrient profile

Meru County is a challenging environment for Chilies (soil-match score 43/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Chilies's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 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 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.
