Growing Capsicum in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a solid choice for Capsicum, with a soil-match score of 63/100. At an average pH of 5.38 the soil is moderately acidic, below Capsicum's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Capsicum prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 90/kg) and a typical 4,500 kg/acre yield, a well-managed Capsicum crop here can gross roughly KES 405,000 per acre.
