Growing Quinoa in Kisumu
Soil suitability analysis based on Kisumu's nutrient profile
Generally not ideal — Kisumu is poorly suited to Quinoa. Kisumu's soil (pH 5.54, slightly acidic) gives Quinoa a suitability score of 28/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.
Kisumu County is a challenging environment for Quinoa (soil-match score 28/100) and will need significant amendment before planting. At an average pH of 5.54 the soil is slightly acidic to near-neutral, below Quinoa's preferred 6–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Quinoa's requirements, so a maintenance fertilizer programme is enough. Quinoa prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Quinoa is the #100 soil match of the 106 crops we assess for Kisumu County. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Kisumu's 28/100 suitability a realistic target here is closer to 245 kg/acre (~KES 36,750/acre) unless the constraints above are addressed.
Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

Kisumu's nitrogen (0.91 g/kg) already meets Quinoa's 0.8 g/kg requirement, so this is a maintenance rate.
