Kisumu County is well suited to Arrow Root, scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 5.54 — 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 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay soils suit Arrow Root, which favours clay loam. At current prices (about KES 55/kg) and a typical 5,000 kg/acre yield, a well-managed Arrow Root crop here can gross roughly KES 275,000 per acre.
