Growing Quinoa in Elgeyo Marakwet

Soil suitability analysis based on Elgeyo Marakwet's nutrient profile

Elgeyo Marakwet County is a solid choice for Quinoa, with a soil-match score of 70/100. Local soils average pH 6.27 — slightly acidic to near-neutral and inside the 6–8.5 band Quinoa prefers, so no lime is usually required. Nitrogen (1.39 g/kg), phosphorus (22.2 mg/kg) and potassium (213 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 Elgeyo Marakwet's 70/100 suitability a realistic target here is closer to 613 kg/acre (~KES 91,950/acre) unless the constraints above are addressed.
