Growing Garden Peas in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Garden Peas (soil-match score 4/100) and will need significant amendment before planting. At an average pH of 7.83 the soil sits above Garden Peas's preferred 5.5–7 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. The county's predominantly sandy soils suit Garden Peas, which favours sandy loam. Isiolo receives approximately 350 mm/year — well below Garden Peas's minimum of 800 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 145/kg) and a typical 2,000 kg/acre yield, a well-managed Garden Peas crop here can gross roughly KES 290,000 per acre.
