Quick answer

Machakos County is well suited to Grapes, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Grapes prefers, so no lime is usually required. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Grapes's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Grapes, which favours loam. On ShambaIQ's soil-match model, Grapes is the #16 soil match of the 106 crops we assess for Machakos County. At current prices (about KES 150/kg) and a typical 8,000 kg/acre yield, a well-managed Grapes crop here can gross roughly KES 1,200,000 per acre.
