Growing Green Grams in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Nandi County is a challenging environment for Green Grams (soil-match score 42/100) and will need significant amendment before planting. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Green Grams, which favours sandy loam. At current prices (about KES 120/kg) and a typical 300 kg/acre yield, a well-managed Green Grams crop here can gross roughly KES 36,000 per acre.
