Growing Sorghum in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Mombasa County is a solid choice for Sorghum, with a soil-match score of 72/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (0.95 g/kg), phosphorus (8.4 mg/kg) and potassium (136 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 68/kg) and a typical 1,200 kg/acre yield, a well-managed Sorghum crop here can gross roughly KES 81,600 per acre.
