Growing Sorghum in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Quick answer

Possible but challenging — Murang'a is only marginally suited to Sorghum. Murang'a's soil (pH 5.03, strongly acidic) gives Sorghum a suitability score of 44/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Murang'a County is a challenging environment for Sorghum (soil-match score 44/100) and will need significant amendment before planting. Local soils average pH 5.03 — moderately acidic and inside the 5–8 band Sorghum prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 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 #88 soil match of the 106 crops we assess for Murang'a County. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Murang'a's 44/100 suitability a realistic target here is closer to 660 kg/acre (~KES 44,880/acre) unless the constraints above are addressed.

Better matched to Murang'a's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
