Growing Green Grams in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Possible but challenging — Nandi is only marginally suited to Green Grams. Nandi's soil (pH 6.17, slightly acidic) gives Green Grams a suitability score of 40/100. Match fertilizer to Nandi's nitrogen and phosphorus levels for the best result.
Nandi County is a challenging environment for Green Grams (soil-match score 40/100) 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. Green Grams prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. Green Grams's full potential is about 400 kg/acre (~KES 48,000/acre at KES 120/kg), but at Nandi's 40/100 suitability a realistic target here is closer to 200 kg/acre (~KES 24,000/acre) unless the constraints above are addressed.
