Growing Arrow Root in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Yes — Mombasa is well suited to Arrow Root. Mombasa's soil (pH 6.24, slightly acidic) gives Arrow Root a suitability score of 84/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.
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. On ShambaIQ's soil-match model, Arrow Root is the #15 soil match of the 106 crops we assess for Mombasa County. 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.

Top dressing guide
Mombasa's nitrogen (0.95 g/kg) already meets Arrow Root's 0.8 g/kg requirement, so this is a maintenance rate.
