Soil suitability analysis based on Kajiado's nutrient profile

Quick answer

Yes — Kajiado is well suited to Watermelon. Kajiado's soil (pH 6.55, near-neutral) gives Watermelon a suitability score of 92/100. Match fertilizer to Kajiado's nitrogen and phosphorus levels for the best result.

Kajiado County is well suited to Watermelon, scoring 92/100 on ShambaIQ's soil-match model. Local soils average pH 6.55 — neutral and inside the 6–7.5 band Watermelon prefers, so no lime is usually required. Nitrogen (0.97 g/kg), phosphorus (20.6 mg/kg) and potassium (257 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. At current prices (about KES 10/kg) and a typical 15,000 kg/acre yield, a well-managed Watermelon crop here can gross roughly KES 150,000 per acre.
