Soil suitability analysis based on Vihiga's nutrient profile
Yes — Vihiga is well suited to Potato. Vihiga's soil (pH 5.62, slightly acidic) gives Potato a suitability score of 77/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Vihiga County is well suited to Potato, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Potato prefers sandy loam soils, while Vihiga is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Potato is the #20 soil match of the 106 crops we assess for Vihiga County. At current prices (about KES 38/kg) and a typical 8,000 kg/acre yield, a well-managed Potato crop here can gross roughly KES 304,000 per acre.
