Growing Sweet Potato in Bungoma

Soil suitability analysis based on Bungoma's nutrient profile

Bungoma County is well suited to Sweet Potato, scoring 91/100 on ShambaIQ's soil-match model. Local soils average pH 5.56 — slightly acidic to near-neutral and inside the 4.5–7 band Sweet Potato prefers, so no lime is usually required. The main gap is potassium — measured at N 1.12 g/kg, P 15.7 mg/kg, K 161 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Sweet Potato, which favours sandy loam. At current prices (about KES 18/kg) and a typical 3,500 kg/acre yield, a well-managed Sweet Potato crop here can gross roughly KES 63,000 per acre.
