Growing Quinoa in Migori
Soil suitability analysis based on Migori's nutrient profile
Generally not ideal — Migori is poorly suited to Quinoa. Migori's soil (pH 5.43, strongly acidic) gives Quinoa a suitability score of 29/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Migori County is a challenging environment for Quinoa (soil-match score 29/100) and will need significant amendment before planting. At an average pH of 5.43 the soil is moderately acidic, below Quinoa's preferred 6–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (169 mg/kg) all meet Quinoa's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Quinoa, which favours loam. On ShambaIQ's soil-match model, Quinoa is the #101 soil match of the 106 crops we assess for Migori County. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Migori's 29/100 suitability a realistic target here is closer to 254 kg/acre (~KES 38,100/acre) unless the constraints above are addressed.
Better matched to Migori's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

Migori's nitrogen (1.2 g/kg) already meets Quinoa's 0.8 g/kg requirement, so this is a maintenance rate.
