Growing Sorghum in Busia

Soil suitability analysis based on Busia's nutrient profile

Quick answer

Generally not ideal — Busia is poorly suited to Sorghum. Busia's soil (pH 5.29, strongly acidic) gives Sorghum a suitability score of 37/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Busia County is a challenging environment for Sorghum (soil-match score 37/100) and will need significant amendment before planting. Local soils average pH 5.29 — moderately acidic and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (16.6 mg/kg) and potassium (175 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 #91 soil match of the 106 crops we assess for Busia County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Busia's 37/100 suitability a realistic target here is closer to 555 kg/acre (~KES 37,740/acre) unless the constraints above are addressed.

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

Busia's nitrogen (0.91 g/kg) already meets Sorghum's 0.5 g/kg requirement, so this is a maintenance rate.
