Growing Mint in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Nandi County is well suited to Mint, scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–7.5 band Mint prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Mint's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Mint, which favours loam. At current prices (about KES 100/kg) and a typical 4,000 kg/acre yield, a well-managed Mint crop here can gross roughly KES 400,000 per acre.
