Growing Snow Peas in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Snow Peas (soil-match score 6/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 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 Isiolo is largely sandy, so drainage and organic-matter management matter more here. Isiolo receives approximately 350 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 Isiolo's 6/100 suitability a realistic target here is closer to 135 kg/acre (~KES 24,975/acre) unless the constraints above are addressed.
