Growing Tea in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Tea (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Tea's preferred 4.5–6.5 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/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Tea 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 Tea's minimum of 1100 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 25/kg) and a typical 2,200 kg/acre yield, a well-managed Tea crop here can gross roughly KES 55,000 per acre.
