Growing Coconuts in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Coconuts (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Coconuts's preferred 5.5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (37.3 mg/kg) and potassium (420 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. Marsabit receives approximately 300 mm/year — well below Coconuts's minimum of 650 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Coconuts is the #105 soil match of the 106 crops we assess for Marsabit County. Coconuts's full potential is about 2,500 kg/acre (~KES 55,000/acre at KES 22/kg), but at Marsabit's 2/100 suitability a realistic target here is closer to 63 kg/acre (~KES 1,386/acre) unless the constraints above are addressed.

Better matched to Marsabit's soil: Sisal, Chia, and Aloe Vera — each scores higher on the same soil.
