Growing Quinoa in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Quinoa can be grown in Laikipia County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 4.99 the soil is strongly acidic, below Quinoa's preferred 6–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Quinoa's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy 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 Laikipia's 59/100 suitability a realistic target here is closer to 516 kg/acre (~KES 77,400/acre) unless the constraints above are addressed.
