Growing Rosemary in Migori

Soil suitability analysis based on Migori's nutrient profile

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. 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.
