Growing Potato in Mandera
Soil suitability analysis based on Mandera's nutrient profile
Generally not ideal — Mandera is poorly suited to Potato. Mandera's soil (pH 8.38, alkaline) gives Potato a suitability score of 0/100. Match fertilizer to Mandera's nitrogen and phosphorus levels for the best result.
Mandera County is a challenging environment for Potato (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.38 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 — measured at N 0.53 g/kg, P 38.3 mg/kg, K 420 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Potato, which favours sandy loam. Mandera receives approximately 180 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 #77 soil match of the 106 crops we assess for Mandera County. Potato's full potential is about 8,000 kg/acre (~KES 304,000/acre at KES 38/kg), but at Mandera's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
Better matched to Mandera's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Mandera's nitrogen (0.53 g/kg) is 44% of the 1.2 g/kg Potato needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
