Growing Lemongrass in Trans Nzoia
Soil suitability analysis based on Trans Nzoia's nutrient profile
Trans Nzoia County is well suited to Lemongrass, scoring 88/100 on ShambaIQ's soil-match model. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5.5–7.5 band Lemongrass prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 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. 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.
