Growing Green Grams in Uasin Gishu
Soil suitability analysis based on Uasin Gishu's nutrient profile
Possible but challenging — Uasin Gishu is only marginally suited to Green Grams. Uasin Gishu's soil (pH 6.39, slightly acidic) gives Green Grams a suitability score of 48/100. Match fertilizer to Uasin Gishu's nitrogen and phosphorus levels for the best result.
Green Grams can be grown in Uasin Gishu County, but the soil scores 48/100 and needs targeted management to reach full potential. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. Green Grams prefers sandy loam soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. Green Grams's full potential is about 400 kg/acre (~KES 48,000/acre at KES 120/kg), but at Uasin Gishu's 48/100 suitability a realistic target here is closer to 240 kg/acre (~KES 28,800/acre) unless the constraints above are addressed.
