Growing Arrow Root in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is well suited to Arrow Root, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5–7 band Arrow Root prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Arrow Root prefers clay loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. 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.
