Growing Cotton in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Quick answer

Yes — Machakos is well suited to Cotton. Machakos's soil (pH 7.03, near-neutral) gives Cotton a suitability score of 90/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.

Machakos County is well suited to Cotton, scoring 90/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 5.8–8 band Cotton prefers, so no lime is usually required. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Cotton's requirements, so a maintenance fertilizer programme is enough. Cotton prefers clay soils, while Machakos is largely sandy loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cotton is the #9 soil match of the 106 crops we assess for Machakos County. 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.
