Growing Quinoa in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Quick answer

Possible but challenging — Bomet is only marginally suited to Quinoa. Bomet's soil (pH 6.02, slightly acidic) gives Quinoa a suitability score of 42/100. Match fertilizer to Bomet's nitrogen and phosphorus levels for the best result.

Bomet County is a challenging environment for Quinoa (soil-match score 42/100) and will need significant amendment before planting. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 6–8.5 band Quinoa prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 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 #88 soil match of the 106 crops we assess for Bomet County. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Bomet's 42/100 suitability a realistic target here is closer to 368 kg/acre (~KES 55,200/acre) unless the constraints above are addressed.

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