Growing Sorghum in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Sorghum can be grown in Samburu County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 8.28 the soil sits above Sorghum's preferred 5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.67 g/kg), phosphorus (42.1 mg/kg) and potassium (387 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sorghum is the #5 soil match of the 106 crops we assess for Samburu County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Samburu's 58/100 suitability a realistic target here is closer to 870 kg/acre (~KES 59,160/acre) unless the constraints above are addressed.

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