Growing Sunflower in Uasin Gishu
Soil suitability analysis based on Uasin Gishu's nutrient profile
Uasin Gishu County is a solid choice for Sunflower, with a soil-match score of 67/100. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 6–7.5 band Sunflower prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Sunflower's requirements, so a maintenance fertilizer programme is enough. Sunflower prefers sandy soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. Sunflower's full potential is about 750 kg/acre (~KES 36,000/acre at KES 48/kg), but at Uasin Gishu's 67/100 suitability a realistic target here is closer to 628 kg/acre (~KES 30,144/acre) unless the constraints above are addressed.
