Growing Quinoa in Nandi
Soil suitability analysis based on Nandi's nutrient profile
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. 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.
