Growing Potato in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Kisii County is well suited to Potato, scoring 80/100 on ShambaIQ's soil-match model. Local soils average pH 5.21 — moderately acidic 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 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. 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.
