Quick answer

Vihiga County is well suited to Lemongrass, scoring 81/100 on ShambaIQ's soil-match model. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 5.5–7.5 band Lemongrass prefers, so no lime is usually required. Nitrogen (1.02 g/kg), phosphorus (14.8 mg/kg) and potassium (164 mg/kg) all meet Lemongrass's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Lemongrass, which favours loam. On ShambaIQ's soil-match model, Lemongrass is the #15 soil match of the 106 crops we assess for Vihiga 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.
