Growing Butternut Squash in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Butternut Squash can be grown in Nyandarua County, but the soil scores 56/100 and needs targeted management to reach full potential. At an average pH of 5.38 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 1.28 g/kg, P 14 mg/kg, K 166 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 Nyandarua is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Butternut Squash is the #59 soil match of the 106 crops we assess for Nyandarua County. Butternut Squash's full potential is about 10,000 kg/acre (~KES 400,000/acre at KES 40/kg), but at Nyandarua's 56/100 suitability a realistic target here is closer to 7,000 kg/acre (~KES 280,000/acre) unless the constraints above are addressed.

Better matched to Nyandarua's soil: Tea, Pyrethrum, and Potato — each scores higher on the same soil.
