Growing Butternut Squash in Embu

Soil suitability analysis based on Embu's nutrient profile

Embu County is a solid choice for Butternut Squash, with a soil-match score of 65/100. At an average pH of 5.1 the soil is moderately acidic, below Butternut Squash's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Butternut Squash prefers sandy loam soils, while Embu is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Butternut Squash is the #38 soil match of the 106 crops we assess for Embu County. Butternut Squash's full potential is about 10,000 kg/acre (~KES 400,000/acre at KES 40/kg), but at Embu's 65/100 suitability a realistic target here is closer to 8,125 kg/acre (~KES 325,000/acre) unless the constraints above are addressed.
