Growing Cotton in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is well suited to Cotton, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 7.5 — alkaline and inside the 5.8–8 band Cotton prefers, so no lime is usually required. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Cotton's requirements, so a maintenance fertilizer programme is enough. Cotton 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 900 kg/acre yield, a well-managed Cotton crop here can gross roughly KES 61,200 per acre.
