Growing Green Grams in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Nyamira County is a challenging environment for Green Grams (soil-match score 38/100) and will need significant amendment before planting. Local soils average pH 5.58 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (0.84 g/kg), phosphorus (11.6 mg/kg) and potassium (148 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.
