Growing Tea in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Tea (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 4.5–6.5 band Tea prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Tea prefers clay soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. Tana River receives approximately 400 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.
