Growing Taro (Nduma) in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Lamu County is a challenging environment for Taro (Nduma) (soil-match score 30/100) and will need significant amendment before planting. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5.5–6.5 band Taro (Nduma) prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Taro (Nduma) prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. Lamu receives approximately 600 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.
