Growing Chia in Meru
Soil suitability analysis based on Meru's nutrient profile
Meru County is a challenging environment for Chia (soil-match score 38/100) and will need significant amendment before planting. At an average pH of 4.88 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 (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. Chia prefers sandy loam soils, while Meru 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 Meru's 38/100 suitability a realistic target here is closer to 190 kg/acre (~KES 28,500/acre) unless the constraints above are addressed.
