Growing Pumpkin in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Pumpkin, with a soil-match score of 65/100. At an average pH of 4.99 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 (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Pumpkin's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Pumpkin, which favours sandy loam. Pumpkin's full potential is about 10,000 kg/acre (~KES 300,000/acre at KES 30/kg), but at Laikipia's 65/100 suitability a realistic target here is closer to 8,125 kg/acre (~KES 243,750/acre) unless the constraints above are addressed.
