Growing Thyme in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Thyme. Turkana's soil (pH 7.95, alkaline) gives Thyme a suitability score of 9/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Thyme (soil-match score 9/100) and will need significant amendment before planting. Local soils average pH 7.95 — alkaline and inside the 6–8 band Thyme prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 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. At 400 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 #55 soil match of the 106 crops we assess for Turkana County. Thyme's full potential is about 2,000 kg/acre (~KES 300,000/acre at KES 150/kg), but at Turkana's 9/100 suitability a realistic target here is closer to 225 kg/acre (~KES 33,750/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Turkana's nitrogen (0.41 g/kg) is 51% of the 0.8 g/kg Thyme needs, so the standard 0.2 bags/acre is raised to 0.25. Split it across two applications to limit leaching.
