Growing Turmeric in Murang'a
Soil suitability analysis based on Murang'a's nutrient profile
Yes, with the right inputs — Murang'a is moderately suited to Turmeric. Murang'a's soil (pH 5.03, strongly acidic) gives Turmeric a suitability score of 59/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Turmeric can be grown in Murang'a County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.03 the soil is moderately acidic, below Turmeric's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Turmeric prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Turmeric is the #61 soil match of the 106 crops we assess for Murang'a County. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Murang'a's 59/100 suitability a realistic target here is closer to 4,425 kg/acre (~KES 354,000/acre) unless the constraints above are addressed.
Better matched to Murang'a's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
