Growing Green Grams in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Wajir County is a challenging environment for Green Grams (soil-match score 38/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Green Grams's preferred 5.5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (39.3 mg/kg) and potassium (396 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy 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.
