Machakos County is well suited to Lucerne, scoring 91/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 6.5–8 band Lucerne prefers, so no lime is usually required. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Lucerne's requirements, so a maintenance fertilizer programme is enough. Lucerne prefers clay loam soils, while Machakos is largely sandy loam, so drainage and organic-matter management matter more here. At current prices (about KES 28/kg) and a typical 8,000 kg/acre yield, a well-managed Lucerne crop here can gross roughly KES 224,000 per acre.
