Growing Sugarcane in Tana River
Soil suitability analysis based on Tana River's nutrient profile
Generally not ideal — Tana River is poorly suited to Sugarcane. Tana River's soil (pH 6.4, slightly acidic) gives Sugarcane a suitability score of 11/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.
Tana River County is a challenging environment for Sugarcane (soil-match score 11/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5.5–7 band Sugarcane prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Sugarcane prefers loam soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. Tana River receives approximately 400 mm/year — well below Sugarcane's minimum of 1100 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Sugarcane is the #59 soil match of the 106 crops we assess for Tana River County. Sugarcane's full potential is about 27,000 kg/acre (~KES 135,000/acre at KES 5/kg), but at Tana River's 11/100 suitability a realistic target here is closer to 3,713 kg/acre (~KES 18,565/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.

Top dressing guide
Tana River's nitrogen (1.04 g/kg) is 87% of the 1.2 g/kg Sugarcane needs, so the standard 1 bag/acre is raised to 1.25. Split it across two applications to limit leaching.
