Growing Rosemary in Migori
Soil suitability analysis based on Migori's nutrient profile
Possible but challenging — Migori is only marginally suited to Rosemary. Migori's soil (pH 5.43, strongly acidic) gives Rosemary a suitability score of 47/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Rosemary can be grown in Migori County, but the soil scores 47/100 and needs targeted management to reach full potential. At an average pH of 5.43 the soil is moderately acidic, below Rosemary's preferred 6–8 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 Rosemary's requirements, so a maintenance fertilizer programme is enough. Rosemary prefers sandy loam soils, while Migori is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Rosemary is the #85 soil match of the 106 crops we assess for Migori County. Rosemary's full potential is about 2,500 kg/acre (~KES 375,000/acre at KES 150/kg), but at Migori's 47/100 suitability a realistic target here is closer to 1,469 kg/acre (~KES 220,350/acre) unless the constraints above are addressed.
Better matched to Migori's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

Top dressing guide
Migori's nitrogen (1.2 g/kg) already meets Rosemary's 0.8 g/kg requirement, so this is a maintenance rate.
