Growing Sorghum in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Sorghum (soil-match score 36/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Sorghum's preferred 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 Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. At current prices (about KES 68/kg) and a typical 1,000 kg/acre yield, a well-managed Sorghum crop here can gross roughly KES 68,000 per acre.
