Growing Chia in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Chia, with a soil-match score of 61/100. At an average pH of 4.99 the soil is strongly acidic, below Chia's preferred 6–8 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 Chia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Chia, which favours sandy loam. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Laikipia's 61/100 suitability a realistic target here is closer to 305 kg/acre (~KES 45,750/acre) unless the constraints above are addressed.
