Growing Potato in Nakuru
Soil suitability analysis based on Nakuru's nutrient profile
Nakuru County is well suited to Potato, scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 mg/kg) all meet Potato's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Potato, which favours sandy loam. At current prices (about KES 32/kg) and a typical 4,000 kg/acre yield, a well-managed Potato crop here can gross roughly KES 128,000 per acre.
