Growing Coffee (Arabica) in Busia

Soil suitability analysis based on Busia's nutrient profile

Quick answer

Yes — Busia is well suited to Coffee (Arabica). Busia's soil (pH 5.29, strongly acidic) gives Coffee (Arabica) a suitability score of 75/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Busia County is well suited to Coffee (Arabica), scoring 75/100 on ShambaIQ's soil-match model. Local soils average pH 5.29 — moderately acidic and inside the 5–6 band Coffee (Arabica) prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 0.91 g/kg, P 16.6 mg/kg, K 175 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 (Arabica), which favours loam. On ShambaIQ's soil-match model, Coffee (Arabica) is the #17 soil match of the 106 crops we assess for Busia County. At current prices (about KES 120/kg) and a typical 800 kg/acre yield, a well-managed Coffee (Arabica) crop here can gross roughly KES 96,000 per acre.
