Growing Pigeon Peas in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Uasin Gishu County is a solid choice for Pigeon Peas, with a soil-match score of 61/100. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5–8 band Pigeon Peas prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Pigeon Peas's requirements, so a maintenance fertilizer programme is enough. Pigeon Peas prefers sandy soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. Pigeon Peas's full potential is about 600 kg/acre (~KES 45,000/acre at KES 75/kg), but at Uasin Gishu's 61/100 suitability a realistic target here is closer to 458 kg/acre (~KES 34,350/acre) unless the constraints above are addressed.
