Growing Thyme in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Thyme (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Thyme's preferred 6–8 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Thyme, which favours sandy loam. Wajir receives approximately 200 mm/year — well below Thyme's minimum of 400 mm — so supplemental irrigation would be essential for this crop. Thyme's full potential is about 2,000 kg/acre (~KES 300,000/acre at KES 150/kg), but at Wajir's 1/100 suitability a realistic target here is closer to 25 kg/acre (~KES 3,750/acre) unless the constraints above are addressed.
