Growing Sorghum in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Sorghum (soil-match score 28/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Sorghum's preferred 5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Sorghum's minimum of 250 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Sorghum is the #4 soil match of the 106 crops we assess for Mandera County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Mandera's 28/100 suitability a realistic target here is closer to 420 kg/acre (~KES 28,560/acre) unless the constraints above are addressed.

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