Growing Sunflower in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Yes, with the right inputs — Nandi is moderately suited to Sunflower. Nandi's soil (pH 6.17, slightly acidic) gives Sunflower a suitability score of 55/100. Match fertilizer to Nandi's nitrogen and phosphorus levels for the best result.
Sunflower can be grown in Nandi County, but the soil scores 55/100 and needs targeted management to reach full potential. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–7.5 band Sunflower prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Sunflower's requirements, so a maintenance fertilizer programme is enough. Sunflower prefers sandy soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sunflower is the #81 soil match of the 106 crops we assess for Nandi County. Sunflower's full potential is about 750 kg/acre (~KES 36,000/acre at KES 48/kg), but at Nandi's 55/100 suitability a realistic target here is closer to 516 kg/acre (~KES 24,768/acre) unless the constraints above are addressed.
Better matched to Nandi's soil: Garden Peas, Maize, and Kale (Sukuma Wiki) — each scores higher on the same soil.
