Growing Sorghum in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Possible but challenging — Kisumu is only marginally suited to Sorghum. Kisumu's soil (pH 5.54, slightly acidic) gives Sorghum a suitability score of 51/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

Sorghum can be grown in Kisumu County, but the soil scores 51/100 and needs targeted management to reach full potential. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay soils suit Sorghum, which favours clay. On ShambaIQ's soil-match model, Sorghum is the #81 soil match of the 106 crops we assess for Kisumu County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Kisumu's 51/100 suitability a realistic target here is closer to 765 kg/acre (~KES 52,020/acre) unless the constraints above are addressed.

Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.
