Growing Cowpeas in Migori

Soil suitability analysis based on Migori's nutrient profile

Quick answer

Generally not ideal — Migori is poorly suited to Cowpeas. Migori's soil (pH 5.43, strongly acidic) gives Cowpeas a suitability score of 39/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Migori County is a challenging environment for Cowpeas (soil-match score 39/100) and will need significant amendment before planting. Local soils average pH 5.43 — moderately acidic and inside the 5–8 band Cowpeas prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (169 mg/kg) all meet Cowpeas's requirements, so a maintenance fertilizer programme is enough. Cowpeas prefers sandy soils, while Migori is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cowpeas is the #91 soil match of the 106 crops we assess for Migori County. Cowpeas's full potential is about 450 kg/acre (~KES 29,250/acre at KES 65/kg), but at Migori's 39/100 suitability a realistic target here is closer to 219 kg/acre (~KES 14,235/acre) unless the constraints above are addressed.

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