Machakos County is a solid choice for African Nightshade, with a soil-match score of 62/100. Local soils average pH 7.03 — neutral and inside the 5.5–7.5 band African Nightshade 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. The county's predominantly sandy loam soils suit African Nightshade, which favours loam. On ShambaIQ's soil-match model, African Nightshade is the #74 soil match of the 106 crops we assess for Machakos County.
