Growing Pumpkin in Meru
Soil suitability analysis based on Meru's nutrient profile
Pumpkin can be grown in Meru County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 4.88 the soil is strongly acidic, below Pumpkin's preferred 5.8–7.5 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 Pumpkin's requirements, so a maintenance fertilizer programme is enough. Pumpkin prefers sandy loam soils, while Meru is largely clay loam, 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 Meru's 58/100 suitability a realistic target here is closer to 7,250 kg/acre (~KES 217,500/acre) unless the constraints above are addressed.
