Growing Quinoa in Busia
Soil suitability analysis based on Busia's nutrient profile
Generally not ideal — Busia is poorly suited to Quinoa. Busia's soil (pH 5.29, strongly acidic) gives Quinoa a suitability score of 24/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Busia County is a challenging environment for Quinoa (soil-match score 24/100) and will need significant amendment before planting. At an average pH of 5.29 the soil is moderately acidic, below Quinoa's preferred 6–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (0.91 g/kg), phosphorus (16.6 mg/kg) and potassium (175 mg/kg) all meet Quinoa's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Quinoa, which favours loam. On ShambaIQ's soil-match model, Quinoa is the #101 soil match of the 106 crops we assess for Busia County. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Busia's 24/100 suitability a realistic target here is closer to 210 kg/acre (~KES 31,500/acre) unless the constraints above are addressed.
Better matched to Busia's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.

Busia's nitrogen (0.91 g/kg) already meets Quinoa's 0.8 g/kg requirement, so this is a maintenance rate.
