Growing Green Grams in Migori
Soil suitability analysis based on Migori's nutrient profile
Generally not ideal — Migori is poorly suited to Green Grams. Migori's soil (pH 5.43, strongly acidic) gives Green Grams a suitability score of 36/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Migori County is a challenging environment for Green Grams (soil-match score 36/100) and will need significant amendment before planting. At an average pH of 5.43 the soil is moderately acidic, below Green Grams's preferred 5.5–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (169 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. Green Grams prefers sandy loam soils, while Migori 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 Migori's 36/100 suitability a realistic target here is closer to 180 kg/acre (~KES 21,600/acre) unless the constraints above are addressed.
