Growing Garden Peas in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Garden 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 band Garden 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. The county's predominantly sandy soils suit Garden Peas, which favours sandy loam. Tana River receives approximately 400 mm/year — well below Garden Peas's minimum of 800 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 145/kg) and a typical 2,000 kg/acre yield, a well-managed Garden Peas crop here can gross roughly KES 290,000 per acre.
