Growing Wheat in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Wheat (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 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 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Wheat prefers clay soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 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.
