Soil suitability analysis based on Meru's nutrient profile
Yes — Meru is well suited to Arrow Root. Meru's soil (pH 4.88, strongly acidic) gives Arrow Root a suitability score of 76/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Meru County is well suited to Arrow Root, scoring 76/100 on ShambaIQ's soil-match model. At an average pH of 4.88 the soil is strongly acidic, below Arrow Root's preferred 5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 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. 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.
