Growing Wheat in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Wheat (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Wheat's preferred 6–7.5 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/medium demand — so the fertilizer plan below prioritises closing that deficit. Wheat prefers clay soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Wheat's minimum of 450 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 50/kg) and a typical 1,000 kg/acre yield, a well-managed Wheat crop here can gross roughly KES 50,000 per acre.
