Growing Sorghum in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Sorghum can be grown in Uasin Gishu County, but the soil scores 49/100 and needs targeted management to reach full potential. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Sorghum, which favours clay. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Uasin Gishu's 49/100 suitability a realistic target here is closer to 735 kg/acre (~KES 49,980/acre) unless the constraints above are addressed.
