Growing Thyme in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Thyme can be grown in Nyeri County, but the soil scores 53/100 and needs targeted management to reach full potential. At an average pH of 5.23 the soil is moderately acidic, below Thyme's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.09 g/kg), phosphorus (15.5 mg/kg) and potassium (192 mg/kg) all meet Thyme's requirements, so a maintenance fertilizer programme is enough. Thyme prefers sandy loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. Thyme's full potential is about 2,000 kg/acre (~KES 300,000/acre at KES 150/kg), but at Nyeri's 53/100 suitability a realistic target here is closer to 1,325 kg/acre (~KES 198,750/acre) unless the constraints above are addressed.
