Growing Thyme in Tana River
Soil suitability analysis based on Tana River's nutrient profile
Tana River County is a challenging environment for Thyme (soil-match score 5/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 6–8 band Thyme prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Thyme, which favours sandy loam. At 200 m, the county sits below Thyme's preferred altitude range (800–2400 m), which limits yield potential due to heat stress. Thyme's full potential is about 2,000 kg/acre (~KES 300,000/acre at KES 150/kg), but at Tana River's 5/100 suitability a realistic target here is closer to 125 kg/acre (~KES 18,750/acre) unless the constraints above are addressed.
