Growing Sorghum in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is well suited to Sorghum, scoring 76/100 on ShambaIQ's soil-match model. Local soils average pH 7.5 — alkaline and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Makueni is largely sandy loam, 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.
