Growing Taro (Nduma) in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Taro (Nduma) (soil-match score 4/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Taro (Nduma)'s preferred 5.5–6.5 range, which can limit uptake of phosphorus and micronutrients. 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. Taro (Nduma) prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Taro (Nduma)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Taro (Nduma) is the #71 soil match of the 106 crops we assess for Turkana County. Taro (Nduma)'s full potential is about 7,000 kg/acre (~KES 630,000/acre at KES 90/kg), but at Turkana's 4/100 suitability a realistic target here is closer to 350 kg/acre (~KES 31,500/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.
