Machakos County is well suited to Basil, scoring 85/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Basil prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.82 g/kg, P 31.4 mg/kg, K 338 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit.
