Growing Butternut Squash in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Quick answer

Yes — Bomet is well suited to Butternut Squash. Bomet's soil (pH 6.02, slightly acidic) gives Butternut Squash a suitability score of 78/100. Match fertilizer to Bomet's nitrogen and phosphorus levels for the best result.

Bomet County is well suited to Butternut Squash, scoring 78/100 on ShambaIQ's soil-match model. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 5.5–7.5 band Butternut Squash prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Butternut Squash's requirements, so a maintenance fertilizer programme is enough. Butternut Squash prefers sandy loam soils, while Bomet is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Butternut Squash is the #50 soil match of the 106 crops we assess for Bomet County. At current prices (about KES 40/kg) and a typical 10,000 kg/acre yield, a well-managed Butternut Squash crop here can gross roughly KES 400,000 per acre.
