Growing Green Grams in Trans Nzoia
Soil suitability analysis based on Trans Nzoia's nutrient profile
Green Grams can be grown in Trans Nzoia County, but the soil scores 51/100 and needs targeted management to reach full potential. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 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.
