Growing Stevia in Migori
Soil suitability analysis based on Migori's nutrient profile
Yes, with the right inputs — Migori is moderately suited to Stevia. Migori's soil (pH 5.43, strongly acidic) gives Stevia a suitability score of 69/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Migori County is a solid choice for Stevia, with a soil-match score of 69/100. At an average pH of 5.43 the soil is moderately acidic, below Stevia's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (169 mg/kg) all meet Stevia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Stevia, which favours loam. On ShambaIQ's soil-match model, Stevia is the #40 soil match of the 106 crops we assess for Migori County. Stevia's full potential is about 3,000 kg/acre (~KES 600,000/acre at KES 200/kg), but at Migori's 69/100 suitability a realistic target here is closer to 2,588 kg/acre (~KES 517,600/acre) unless the constraints above are addressed.
