Growing Wambugu Apples in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Wambugu Apples (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Wambugu Apples's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Wambugu Apples prefers loam soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 mm/year — well below Wambugu Apples's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 75/kg) and a typical 2,000 kg/acre yield, a well-managed Wambugu Apples crop here can gross roughly KES 150,000 per acre.
