Growing Pumpkin in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a solid choice for Pumpkin, with a soil-match score of 66/100. At an average pH of 5.31 the soil is moderately acidic, below Pumpkin's preferred 5.8–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.36 g/kg, P 12.5 mg/kg, K 177 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Pumpkin prefers sandy loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. Pumpkin's full potential is about 10,000 kg/acre (~KES 300,000/acre at KES 30/kg), but at Kirinyaga's 66/100 suitability a realistic target here is closer to 8,250 kg/acre (~KES 247,500/acre) unless the constraints above are addressed.
