Growing Passion Fruit in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Passion Fruit (soil-match score 5/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Passion Fruit's preferred 5.5–7.5 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/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Passion Fruit prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 mm/year — well below Passion Fruit's minimum of 900 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 70/kg) and a typical 4,500 kg/acre yield, a well-managed Passion Fruit crop here can gross roughly KES 315,000 per acre.
