Growing Potato in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Potato, with a soil-match score of 61/100. Local soils average pH 4.99 — strongly acidic and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. The main gap is phosphorus — measured at N 1.42 g/kg, P 16.6 mg/kg, K 215 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy 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.
