Growing Watermelon in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a solid choice for Watermelon, with a soil-match score of 65/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Watermelon prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Watermelon, which favours sandy. 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.
