Growing Cassava in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Cassava can be grown in Tana River County, but the soil scores 53/100 and needs targeted management to reach full potential. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 4.5–7 band Cassava 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/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Cassava, which favours sandy. Cassava's full potential is about 6,000 kg/acre (~KES 90,000/acre at KES 15/kg), but at Tana River's 53/100 suitability a realistic target here is closer to 3,975 kg/acre (~KES 59,625/acre) unless the constraints above are addressed.
