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. On ShambaIQ's soil-match model, Sorghum is the #4 soil match of the 106 crops we assess for Wajir County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Wajir's 36/100 suitability a realistic target here is closer to 540 kg/acre (~KES 36,720/acre) unless the constraints above are addressed.

Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
