Growing Cotton in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Possible but challenging — Nandi is only marginally suited to Cotton. Nandi's soil (pH 6.17, slightly acidic) gives Cotton a suitability score of 49/100. Match fertilizer to Nandi's nitrogen and phosphorus levels for the best result.
Cotton can be grown in Nandi County, but the soil scores 49/100 and needs targeted management to reach full potential. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5.8–8 band Cotton prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Cotton's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Cotton, which favours clay. At 1900 m, the county sits above Cotton's preferred altitude ceiling of 1500 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Cotton is the #85 soil match of the 106 crops we assess for Nandi County. Cotton's full potential is about 900 kg/acre (~KES 61,200/acre at KES 68/kg), but at Nandi's 49/100 suitability a realistic target here is closer to 551 kg/acre (~KES 37,468/acre) unless the constraints above are addressed.
Better matched to Nandi's soil: Garden Peas, Maize, and Kale (Sukuma Wiki) — each scores higher on the same soil.

Top dressing guide
Nandi's nitrogen (1.37 g/kg) already meets Cotton's 0.8 g/kg requirement, so this is a maintenance rate.
