Growing Arrow Root in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Kakamega County is well suited to Arrow Root, scoring 88/100 on ShambaIQ's soil-match model. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 5–7 band Arrow Root prefers, so no lime is usually required. The main gap is potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Arrow Root, which favours clay loam. At current prices (about KES 55/kg) and a typical 4,500 kg/acre yield, a well-managed Arrow Root crop here can gross roughly KES 247,500 per acre.
