Growing Quinoa in Homa Bay
Soil suitability analysis based on Homa Bay's nutrient profile
Generally not ideal — Homa Bay is poorly suited to Quinoa. Homa Bay's soil (pH 5.27, strongly acidic) gives Quinoa a suitability score of 31/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Homa Bay County is a challenging environment for Quinoa (soil-match score 31/100) and will need significant amendment before planting. At an average pH of 5.27 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. The main gap is potassium — measured at N 1.05 g/kg, P 13.8 mg/kg, K 147 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Quinoa, which favours loam. On ShambaIQ's soil-match model, Quinoa is the #100 soil match of the 106 crops we assess for Homa Bay County. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Homa Bay's 31/100 suitability a realistic target here is closer to 271 kg/acre (~KES 40,650/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.
