Growing Snow Peas in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Lamu County is a challenging environment for Snow Peas (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.31 — 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 0.74 g/kg, P 9.6 mg/kg, K 117 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 Lamu is largely sandy, so drainage and organic-matter management matter more here. At 10 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 Lamu's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
