Growing Broccoli in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Broccoli (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Broccoli's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.53 g/kg, P 38.3 mg/kg, K 420 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Broccoli prefers loam soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Broccoli's minimum of 800 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 90/kg) and a typical 5,000 kg/acre yield, a well-managed Broccoli crop here can gross roughly KES 450,000 per acre.
