Growing Snow Peas in Lamu
Soil suitability analysis based on Lamu's nutrient profile
Generally not ideal — Lamu is poorly suited to Snow Peas. Lamu's soil (pH 6.31, slightly acidic) gives Snow Peas a suitability score of 0/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.
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. On ShambaIQ's soil-match model, Snow Peas is the #74 soil match of the 106 crops we assess for Lamu County. 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.
Better matched to Lamu's soil: Sesame (Simsim), Sorghum, and Cowpeas — each scores higher on the same soil.

| Altitude | 10 m | 1,500–3,000 m | Low |
Top dressing guide
Lamu's nitrogen reads 0.74 g/kg, but the rate stays at zero: Snow Peas is not top-dressed, for the crop-specific reason above.
Recommended seed varieties
No variety in our list is specifically rated for Lamu's 10 m altitude and 600 mm rainfall, so all 2 are shown. Confirm with your agrovet before buying.
