Growing Thyme in Tharaka Nithi
Soil suitability analysis based on Tharaka Nithi's nutrient profile
Yes, with the right inputs — Tharaka Nithi is moderately suited to Thyme. Tharaka Nithi's soil (pH 4.99, strongly acidic) gives Thyme a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Tharaka Nithi County is a solid choice for Thyme, with a soil-match score of 61/100. At an average pH of 4.99 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 (1.23 g/kg), phosphorus (19.6 mg/kg) and potassium (211 mg/kg) all meet Thyme's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Thyme, which favours sandy loam. On ShambaIQ's soil-match model, Thyme is the #61 soil match of the 106 crops we assess for Tharaka Nithi County. Thyme's full potential is about 2,000 kg/acre (~KES 300,000/acre at KES 150/kg), but at Tharaka Nithi's 61/100 suitability a realistic target here is closer to 1,525 kg/acre (~KES 228,750/acre) unless the constraints above are addressed.
