Growing Snow Peas in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Snow Peas (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Snow Peas's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Snow Peas prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Snow Peas's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Snow Peas's full potential is about 1,800 kg/acre (~KES 333,000/acre at KES 185/kg), but at Turkana's 1/100 suitability a realistic target here is closer to 23 kg/acre (~KES 4,255/acre) unless the constraints above are addressed.
