Growing Sorghum in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is well suited to Sorghum, scoring 92/100 on ShambaIQ's soil-match model. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (1.04 g/kg), phosphorus (8.5 mg/kg) and potassium (108 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Tana River 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.
