Growing Snow Peas in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Snow Peas (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 5.5–7.5 band Snow Peas prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Snow Peas prefers loam 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 Snow Peas's minimum of 700 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 185/kg) and a typical 1,300 kg/acre yield, a well-managed Snow Peas crop here can gross roughly KES 240,500 per acre.
