Growing Coconuts in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Quick answer

Generally not ideal — Wajir is poorly suited to Coconuts. Wajir's soil (pH 8.4, alkaline) gives Coconuts a suitability score of 6/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.

Wajir County is a challenging environment for Coconuts (soil-match score 6/100) and will need significant amendment before planting. At an average pH of 8.4 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 (39.3 mg/kg) and potassium (396 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. Wajir receives approximately 200 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 #39 soil match of the 106 crops we assess for Wajir County. Coconuts's full potential is about 2,500 kg/acre (~KES 55,000/acre at KES 22/kg), but at Wajir's 6/100 suitability a realistic target here is closer to 188 kg/acre (~KES 4,136/acre) unless the constraints above are addressed.

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