Growing Sorghum in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Yes — Nairobi is well suited to Sorghum. Nairobi's soil (pH 6.85, near-neutral) gives Sorghum a suitability score of 79/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.
Nairobi County is well suited to Sorghum, scoring 79/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Sorghum, which favours clay. On ShambaIQ's soil-match model, Sorghum is the #70 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 68/kg) and a typical 1,200 kg/acre yield, a well-managed Sorghum crop here can gross roughly KES 81,600 per acre.
