Growing Cabbage in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Cabbage (soil-match score 9/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Cabbage's preferred 5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 37.3 mg/kg, K 420 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Cabbage prefers clay loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 mm/year — well below Cabbage's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Marsabit's 9/100 suitability a realistic target here is closer to 1,688 kg/acre (~KES 30,384/acre) unless the constraints above are addressed.
