Growing Taro (Nduma) in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Taita Taveta County is a challenging environment for Taro (Nduma) (soil-match score 21/100) and will need significant amendment before planting. At an average pH of 6.64 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 potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly loam soils suit Taro (Nduma), which favours loam. Taita Taveta receives approximately 500 mm/year — well below Taro (Nduma)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 90/kg) and a typical 8,000 kg/acre yield, a well-managed Taro (Nduma) crop here can gross roughly KES 720,000 per acre.
