Growing Watermelon in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Bomet County is a challenging environment for Watermelon (soil-match score 31/100) and will need significant amendment before planting. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 6–7.5 band Watermelon prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Watermelon's requirements, so a maintenance fertilizer programme is enough. Watermelon prefers sandy soils, while Bomet is largely clay loam, so drainage and organic-matter management matter more here. At 1900 m, the county sits above Watermelon's preferred altitude ceiling of 1500 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 10/kg) and a typical 5,500 kg/acre yield, a well-managed Watermelon crop here can gross roughly KES 55,000 per acre.
