Growing Arrow Root in Baringo
Soil suitability analysis based on Baringo's nutrient profile
Possible but challenging — Baringo is only marginally suited to Arrow Root. Baringo's soil (pH 6.22, slightly acidic) gives Arrow Root a suitability score of 45/100. Match fertilizer to Baringo's nitrogen and phosphorus levels for the best result.
Arrow Root can be grown in Baringo County, but the soil scores 45/100 and needs targeted management to reach full potential. Local soils average pH 6.22 — slightly acidic to near-neutral and inside the 5–7 band Arrow Root prefers, so no lime is usually required. Nitrogen (1.32 g/kg), phosphorus (23.4 mg/kg) and potassium (212 mg/kg) all meet Arrow Root's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Arrow Root, which favours clay loam. Baringo receives approximately 700 mm/year — well below Arrow Root's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. Arrow Root's full potential is about 5,000 kg/acre (~KES 275,000/acre at KES 55/kg), but at Baringo's 45/100 suitability a realistic target here is closer to 2,813 kg/acre (~KES 154,715/acre) unless the constraints above are addressed.
