Growing Pineapple in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Pineapple (soil-match score 12/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 4.5–6.5 band Pineapple 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 medium/low/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Pineapple, which favours sandy loam. Tana River receives approximately 400 mm/year — well below Pineapple's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Pineapple is the #57 soil match of the 106 crops we assess for Tana River County. Pineapple's full potential is about 25,000 kg/acre (~KES 875,000/acre at KES 35/kg), but at Tana River's 12/100 suitability a realistic target here is closer to 3,750 kg/acre (~KES 131,250/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.
