Growing Capsicum in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Murang'a County is a solid choice for Capsicum, with a soil-match score of 65/100. At an average pH of 5.03 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 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Capsicum prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. Capsicum's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Murang'a's 65/100 suitability a realistic target here is closer to 4,875 kg/acre (~KES 438,750/acre) unless the constraints above are addressed.
