Growing Sorghum in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Quick answer

Yes — Kwale is well suited to Sorghum. Kwale's soil (pH 6.76, near-neutral) gives Sorghum a suitability score of 79/100. Match fertilizer to Kwale's nitrogen and phosphorus levels for the best result.

Kwale County is well suited to Sorghum, scoring 79/100 on ShambaIQ's soil-match model. Local soils average pH 6.76 — neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (0.93 g/kg), phosphorus (9.8 mg/kg) and potassium (131 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Kwale is largely sandy loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sorghum is the #35 soil match of the 106 crops we assess for Kwale County. 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.
