Growing Sorghum in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Yes, with the right inputs — Turkana is moderately suited to Sorghum. Turkana's soil (pH 7.95, alkaline) gives Sorghum a suitability score of 60/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a solid choice for Sorghum, with a soil-match score of 60/100. Local soils average pH 7.95 — alkaline and inside the 5–8 band Sorghum prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/low/low demand — so the fertilizer plan below prioritises closing that deficit. Sorghum prefers clay soils, while Turkana 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 Turkana County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Turkana's 60/100 suitability a realistic target here is closer to 900 kg/acre (~KES 61,200/acre) unless the constraints above are addressed.

Top dressing guide
Turkana's nitrogen (0.41 g/kg) is 82% of the 0.5 g/kg Sorghum needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
