Growing Chia in Homa Bay
Soil suitability analysis based on Homa Bay's nutrient profile
Possible but challenging — Homa Bay is only marginally suited to Chia. Homa Bay's soil (pH 5.27, strongly acidic) gives Chia a suitability score of 52/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Chia can be grown in Homa Bay County, but the soil scores 52/100 and needs targeted management to reach full potential. At an average pH of 5.27 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 (1.05 g/kg), phosphorus (13.8 mg/kg) and potassium (147 mg/kg) all meet Chia's requirements, so a maintenance fertilizer programme is enough. Chia prefers sandy loam soils, while Homa Bay is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Chia is the #85 soil match of the 106 crops we assess for Homa Bay County. Chia's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Homa Bay'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 Homa Bay's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.

Homa Bay's nitrogen (1.05 g/kg) already meets Chia's 0.5 g/kg requirement, so this is a maintenance rate.
