Growing Potato in Elgeyo Marakwet

Soil suitability analysis based on Elgeyo Marakwet's nutrient profile

Quick answer

Yes — Elgeyo Marakwet is well suited to Potato. Elgeyo Marakwet's soil (pH 6.27, slightly acidic) gives Potato a suitability score of 85/100. Match fertilizer to Elgeyo Marakwet's nitrogen and phosphorus levels for the best result.

Elgeyo Marakwet County is well suited to Potato, scoring 85/100 on ShambaIQ's soil-match model. Local soils average pH 6.27 — slightly acidic to near-neutral and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. Nitrogen (1.39 g/kg), phosphorus (22.2 mg/kg) and potassium (213 mg/kg) all meet Potato's requirements, so a maintenance fertilizer programme is enough. Potato prefers sandy loam soils, while Elgeyo Marakwet is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Potato is the #62 soil match of the 106 crops we assess for Elgeyo Marakwet 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.
