Growing Chia in Nandi

Soil suitability analysis based on Nandi's nutrient profile

Quick answer

Possible but challenging — Nandi is only marginally suited to Chia. Nandi's soil (pH 6.17, slightly acidic) gives Chia a suitability score of 52/100. Match fertilizer to Nandi's nitrogen and phosphorus levels for the best result.

Chia can be grown in Nandi County, but the soil scores 52/100 and needs targeted management to reach full potential. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–8 band Chia prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. Chia prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Chia is the #82 soil match of the 106 crops we assess for Nandi County. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Nandi's 52/100 suitability a realistic target here is closer to 260 kg/acre (~KES 39,000/acre) unless the constraints above are addressed.

Better matched to Nandi's soil: Garden Peas, Maize, and Kale (Sukuma Wiki) — each scores higher on the same soil.
