Growing Thyme in Meru

Soil suitability analysis based on Meru's nutrient profile

Meru County is a challenging environment for Thyme (soil-match score 43/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Thyme's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Thyme's requirements, so a maintenance fertilizer programme is enough. Thyme prefers sandy loam soils, while Meru is largely clay loam, 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 Meru's 43/100 suitability a realistic target here is closer to 1,075 kg/acre (~KES 161,250/acre) unless the constraints above are addressed.
