Growing Thyme in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Quick answer

Generally not ideal — Kwale is poorly suited to Thyme. Kwale's soil (pH 6.76, near-neutral) gives Thyme a suitability score of 5/100. Match fertilizer to Kwale's nitrogen and phosphorus levels for the best result.

Kwale County is a challenging environment for Thyme (soil-match score 5/100) and will need significant amendment before planting. Local soils average pH 6.76 — 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 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam 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. On ShambaIQ's soil-match model, Thyme is the #74 soil match of the 106 crops we assess for Kwale County. Thyme's full potential is about 2,000 kg/acre (~KES 300,000/acre at KES 150/kg), but at Kwale's 5/100 suitability a realistic target here is closer to 125 kg/acre (~KES 18,750/acre) unless the constraints above are addressed.

Better matched to Kwale's soil: Dhania, Pigeon Peas, and Mango — each scores higher on the same soil.
