Growing Chia in Busia
Soil suitability analysis based on Busia's nutrient profile
Busia County is a challenging environment for Chia (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 5.29 the soil is moderately acidic, below Chia's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (0.91 g/kg), phosphorus (16.6 mg/kg) and potassium (175 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. Chia prefers sandy loam soils, while Busia is largely clay loam, so drainage and organic-matter management matter more here. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Busia's 41/100 suitability a realistic target here is closer to 205 kg/acre (~KES 30,750/acre) unless the constraints above are addressed.
