Growing Coffee (Arabica) in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Murang'a County is well suited to Coffee (Arabica), scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 5.03 — moderately acidic and inside the 5–6 band Coffee (Arabica) prefers, so no lime is usually required. The main gap is potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Coffee (Arabica) prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. 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.
