Growing Quinoa in Nandi
Soil suitability analysis based on Nandi's nutrient profile
Possible but challenging — Nandi is only marginally suited to Quinoa. Nandi's soil (pH 6.17, slightly acidic) gives Quinoa a suitability score of 48/100. Match fertilizer to Nandi's nitrogen and phosphorus levels for the best result.
Quinoa can be grown in Nandi County, but the soil scores 48/100 and needs targeted management to reach full potential. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–8.5 band Quinoa prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 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 #87 soil match of the 106 crops we assess for Nandi County. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Nandi's 48/100 suitability a realistic target here is closer to 420 kg/acre (~KES 63,000/acre) unless the constraints above are addressed.
Better matched to Nandi's soil: Garden Peas, Maize, and Kale (Sukuma Wiki) — each scores higher on the same soil.
