Growing Coconuts in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Quick answer

Generally not ideal — Tana River is poorly suited to Coconuts. Tana River's soil (pH 6.4, slightly acidic) gives Coconuts a suitability score of 33/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.

Tana River County is a challenging environment for Coconuts (soil-match score 33/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5.5–8 band Coconuts prefers, so no lime is usually required. The main gap is potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's low/low/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Coconuts, which favours sandy. Tana River receives approximately 400 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 #46 soil match of the 106 crops we assess for Tana River County. Coconuts's full potential is about 2,500 kg/acre (~KES 55,000/acre at KES 22/kg), but at Tana River's 33/100 suitability a realistic target here is closer to 1,031 kg/acre (~KES 22,682/acre) unless the constraints above are addressed.

Better matched to Tana River's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.

Tana River's nitrogen (1.04 g/kg) already meets Coconuts's 0.5 g/kg requirement, so this is a maintenance rate.
