Growing Chia in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Possible but challenging — Kisumu is only marginally suited to Chia. Kisumu's soil (pH 5.54, slightly acidic) gives Chia a suitability score of 51/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

Chia can be grown in Kisumu County, but the soil scores 51/100 and needs targeted management to reach full potential. At an average pH of 5.54 the soil is slightly acidic to near-neutral, 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 (12.5 mg/kg) and potassium (166 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. Chia prefers sandy loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Chia is the #86 soil match of the 106 crops we assess for Kisumu County. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Kisumu's 51/100 suitability a realistic target here is closer to 255 kg/acre (~KES 38,250/acre) unless the constraints above are addressed.

Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.
