Growing Coconuts in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for Coconuts (soil-match score 11/100) and will need significant amendment before planting. Local soils average pH 7.96 — alkaline and inside the 5.5–8 band Coconuts prefers, so no lime is usually required. Nitrogen (0.61 g/kg), phosphorus (37.7 mg/kg) and potassium (407 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. Garissa receives approximately 250 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.
