Growing Yams in Nakuru
Soil suitability analysis based on Nakuru's nutrient profile
Possible but challenging — Nakuru is only marginally suited to Yams. Nakuru's soil (pH 6.28, slightly acidic) gives Yams a suitability score of 52/100. Match fertilizer to Nakuru's nitrogen and phosphorus levels for the best result.
Yams can be grown in Nakuru County, but the soil scores 52/100 and needs targeted management to reach full potential. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 5.5–6.5 band Yams prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 mg/kg) all meet Yams's requirements, so a maintenance fertilizer programme is enough. Yams prefers sandy loam soils, while Nakuru is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Yams is the #94 soil match of the 106 crops we assess for Nakuru County. Yams's full potential is about 7,000 kg/acre (~KES 560,000/acre at KES 80/kg), but at Nakuru's 52/100 suitability a realistic target here is closer to 4,550 kg/acre (~KES 364,000/acre) unless the constraints above are addressed.
Better matched to Nakuru's soil: Carrot, Dolichos, and Garden Peas — each scores higher on the same soil.
