Growing Cotton in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a solid choice for Cotton, with a soil-match score of 64/100. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5.8–8 band Cotton prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Cotton prefers clay soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. Cotton's full potential is about 900 kg/acre (~KES 61,200/acre at KES 68/kg), but at Tana River's 64/100 suitability a realistic target here is closer to 720 kg/acre (~KES 48,960/acre) unless the constraints above are addressed.
