Growing Watermelon in West Pokot

Soil suitability analysis based on West Pokot's nutrient profile

Quick answer

Yes, with the right inputs — West Pokot is moderately suited to Watermelon. West Pokot's soil (pH 6.04, slightly acidic) gives Watermelon a suitability score of 67/100. Match fertilizer to West Pokot's nitrogen and phosphorus levels for the best result.

West Pokot County is a solid choice for Watermelon, with a soil-match score of 67/100. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 6–7.5 band Watermelon prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Watermelon's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Watermelon, which favours sandy. Watermelon's full potential is about 15,000 kg/acre (~KES 150,000/acre at KES 10/kg), but at West Pokot's 67/100 suitability a realistic target here is closer to 12,563 kg/acre (~KES 125,630/acre) unless the constraints above are addressed.
