Growing Garden Peas in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a challenging environment for Garden Peas (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.24 — 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 0.95 g/kg, P 8.4 mg/kg, K 136 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. At 50 m, the county sits below Garden Peas's preferred altitude range (1500–2600 m), which limits yield potential due to heat stress. 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.
