Growing Coffee (Robusta) in Kakamega
Soil suitability analysis based on Kakamega's nutrient profile
Yes, with the right inputs — Kakamega is moderately suited to Coffee (Robusta). Kakamega's soil (pH 5.63, slightly acidic) gives Coffee (Robusta) a suitability score of 56/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.
Coffee (Robusta) can be grown in Kakamega County, but the soil scores 56/100 and needs targeted management to reach full potential. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 5–6.5 band Coffee (Robusta) prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Coffee (Robusta), which favours loam. At 1500 m, the county sits above Coffee (Robusta)'s preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Coffee (Robusta) is the #50 soil match of the 106 crops we assess for Kakamega County. Coffee (Robusta)'s full potential is about 950 kg/acre (~KES 76,000/acre at KES 80/kg), but at Kakamega's 56/100 suitability a realistic target here is closer to 665 kg/acre (~KES 53,200/acre) unless the constraints above are addressed.
Better matched to Kakamega's soil: Soybeans, Rice (Lowland/Paddy), and Sweet Potato — each scores higher on the same soil.
