Growing Snow Peas in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Snow Peas (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.76 — 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 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Snow Peas, which favours loam. At 200 m, the county sits below Snow Peas's preferred altitude range (1500–3000 m), which limits yield potential due to heat stress. Snow Peas's full potential is about 1,800 kg/acre (~KES 333,000/acre at KES 185/kg), but at Kwale's 2/100 suitability a realistic target here is closer to 45 kg/acre (~KES 8,325/acre) unless the constraints above are addressed.
