Soil suitability analysis based on Kericho's nutrient profile
Kericho County is well suited to Arrow Root, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 5.94 — slightly acidic to near-neutral and inside the 5–7 band Arrow Root prefers, so no lime is usually required. Nitrogen (1.34 g/kg), phosphorus (23.7 mg/kg) and potassium (225 mg/kg) all meet Arrow Root's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay soils suit Arrow Root, which favours clay loam.
