Quick answer

Yes — Machakos is well suited to Lemongrass. Machakos's soil (pH 7.03, near-neutral) gives Lemongrass a suitability score of 86/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.

Machakos County is well suited to Lemongrass, scoring 86/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 5.5–7.5 band Lemongrass prefers, so no lime is usually required. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Lemongrass's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Lemongrass, which favours loam. On ShambaIQ's soil-match model, Lemongrass is the #27 soil match of the 106 crops we assess for Machakos County. At current prices (about KES 60/kg) and a typical 8,000 kg/acre yield, a well-managed Lemongrass crop here can gross roughly KES 480,000 per acre.
