Machakos County is well suited to Sorghum, scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Machakos is largely sandy loam, so drainage and organic-matter management matter more here.

At current prices (about KES 68/kg) and a typical 1,200 kg/acre yield, a well-managed Sorghum crop here can gross roughly KES 81,600 per acre.
