Growing Beetroot in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Quick answer

Generally not ideal — Tana River is poorly suited to Beetroot. Tana River's soil (pH 6.4, slightly acidic) gives Beetroot a suitability score of 3/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.

Tana River County is a challenging environment for Beetroot (soil-match score 3/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 6–7.5 band Beetroot 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/high/high demand — so the fertilizer plan below prioritises closing those deficits. Beetroot prefers loam soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. At 200 m, the county sits below Beetroot's preferred altitude range (800–2500 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Beetroot is the #73 soil match of the 106 crops we assess for Tana River County. Beetroot's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Tana River's 3/100 suitability a realistic target here is closer to 375 kg/acre (~KES 18,750/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.

Bags per acre in Tana River
0.50.4

Tana River's nitrogen (1.04 g/kg) is 87% of the 1.2 g/kg Beetroot needs, so the standard 0.4 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
