Growing Potato in Taita Taveta
Soil suitability analysis based on Taita Taveta's nutrient profile
Generally not ideal — Taita Taveta is poorly suited to Potato. Taita Taveta's soil (pH 6.64, near-neutral) gives Potato a suitability score of 7/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.
Taita Taveta County is a challenging environment for Potato (soil-match score 7/100) and will need significant amendment before planting. At an average pH of 6.64 the soil sits above Potato's preferred 4.8–6.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly loam soils suit Potato, which favours sandy loam. Taita Taveta receives approximately 500 mm/year — well below Potato's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Potato is the #99 soil match of the 106 crops we assess for Taita Taveta County. Potato's full potential is about 8,000 kg/acre (~KES 304,000/acre at KES 38/kg), but at Taita Taveta's 7/100 suitability a realistic target here is closer to 700 kg/acre (~KES 26,600/acre) unless the constraints above are addressed.
Better matched to Taita Taveta's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
