Kwale County is a solid choice for Taro (Nduma), with a soil-match score of 64/100. At an average pH of 6.76 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 phosphorus and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Taro (Nduma), which favours loam. On ShambaIQ's soil-match model, Taro (Nduma) is the #55 soil match of the 106 crops we assess for Kwale County.
