Growing Groundnuts in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Uasin Gishu County is a solid choice for Groundnuts, with a soil-match score of 67/100. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5–7 band Groundnuts prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Groundnuts's requirements, so a maintenance fertilizer programme is enough. Groundnuts prefers sandy soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. Groundnuts's full potential is about 500 kg/acre (~KES 45,000/acre at KES 90/kg), but at Uasin Gishu's 67/100 suitability a realistic target here is closer to 419 kg/acre (~KES 37,710/acre) unless the constraints above are addressed.
