Growing Cassava in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Quick answer

Yes, with the right inputs — Kakamega is moderately suited to Cassava. Kakamega's soil (pH 5.63, slightly acidic) gives Cassava a suitability score of 70/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.

Kakamega County is a solid choice for Cassava, with a soil-match score of 70/100. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 4.5–7 band Cassava prefers, so no lime is usually required. The main gap is potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's low/low/medium demand — so the fertilizer plan below prioritises closing that deficit. Cassava prefers sandy soils, while Kakamega is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cassava is the #32 soil match of the 106 crops we assess for Kakamega County. Cassava's full potential is about 6,000 kg/acre (~KES 90,000/acre at KES 15/kg), but at Kakamega's 70/100 suitability a realistic target here is closer to 5,250 kg/acre (~KES 78,750/acre) unless the constraints above are addressed.
