Growing Chia in Meru

Soil suitability analysis based on Meru's nutrient profile

Quick answer

Generally not ideal — Meru is poorly suited to Chia. Meru's soil (pH 4.88, strongly acidic) gives Chia a suitability score of 38/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

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. On ShambaIQ's soil-match model, Chia is the #90 soil match of the 106 crops we assess for Meru County. 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.

Better matched to Meru's soil: Tea, Avocado, and Macadamia — each scores higher on the same soil.

Meru's nitrogen (1.22 g/kg) already meets Chia's 0.5 g/kg requirement, so this is a maintenance rate.
