Growing Cabbage in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for Cabbage (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.96 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 0.61 g/kg, P 37.7 mg/kg, K 407 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 Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Cabbage's minimum of 700 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 12/kg) and a typical 10,000 kg/acre yield, a well-managed Cabbage crop here can gross roughly KES 120,000 per acre.
