Growing Coconuts in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Coconuts (soil-match score 9/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Coconuts's preferred 5.5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.67 g/kg), phosphorus (42.1 mg/kg) and potassium (387 mg/kg) all meet Coconuts's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Coconuts, which favours sandy. Samburu receives approximately 350 mm/year — well below Coconuts's minimum of 650 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 22/kg) and a typical 2,500 kg/acre yield, a well-managed Coconuts crop here can gross roughly KES 55,000 per acre.
