Growing Sorghum in Bungoma

Soil suitability analysis based on Bungoma's nutrient profile

Quick answer

Possible but challenging — Bungoma is only marginally suited to Sorghum. Bungoma's soil (pH 5.56, slightly acidic) gives Sorghum a suitability score of 40/100. Match fertilizer to Bungoma's nitrogen and phosphorus levels for the best result.

Bungoma County is a challenging environment for Sorghum (soil-match score 40/100) and will need significant amendment before planting. Local soils average pH 5.56 — slightly acidic to near-neutral and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (1.12 g/kg), phosphorus (15.7 mg/kg) and potassium (161 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 #93 soil match of the 106 crops we assess for Bungoma County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Bungoma's 40/100 suitability a realistic target here is closer to 600 kg/acre (~KES 40,800/acre) unless the constraints above are addressed.

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