Growing Green Grams in Kericho
Soil suitability analysis based on Kericho's nutrient profile
Generally not ideal — Kericho is poorly suited to Green Grams. Kericho's soil (pH 5.94, slightly acidic) gives Green Grams a suitability score of 34/100. Match fertilizer to Kericho's nitrogen and phosphorus levels for the best result.
Kericho County is a challenging environment for Green Grams (soil-match score 34/100) and will need significant amendment before planting. Local soils average pH 5.94 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (1.34 g/kg), phosphorus (23.7 mg/kg) and potassium (225 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. Green Grams prefers sandy loam soils, while Kericho is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Green Grams is the #94 soil match of the 106 crops we assess for Kericho County. Green Grams's full potential is about 400 kg/acre (~KES 48,000/acre at KES 120/kg), but at Kericho's 34/100 suitability a realistic target here is closer to 170 kg/acre (~KES 20,400/acre) unless the constraints above are addressed.
Better matched to Kericho's soil: Kale (Sukuma Wiki), Sweet Potato, and Wambugu Apples — each scores higher on the same soil.
