Nyandarua County is well suited to Coffee (Arabica), scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 5.38 — 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 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit.
