Growing Turmeric in Meru
Soil suitability analysis based on Meru's nutrient profile
Yes, with the right inputs — Meru is moderately suited to Turmeric. Meru's soil (pH 4.88, strongly acidic) gives Turmeric a suitability score of 63/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Meru County is a solid choice for Turmeric, with a soil-match score of 63/100. At an average pH of 4.88 the soil is strongly acidic, below Turmeric's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Turmeric's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Turmeric, which favours loam. On ShambaIQ's soil-match model, Turmeric is the #40 soil match of the 106 crops we assess for Meru County. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Meru's 63/100 suitability a realistic target here is closer to 4,725 kg/acre (~KES 378,000/acre) unless the constraints above are addressed.
