Growing Chilies in Tana River
Soil suitability analysis based on Tana River's nutrient profile
Possible but challenging — Tana River is only marginally suited to Chilies. Tana River's soil (pH 6.4, slightly acidic) gives Chilies a suitability score of 53/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.
Chilies 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 6–7.5 band Chilies prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Chilies, which favours sandy loam. Chilies's full potential is about 2,500 kg/acre (~KES 412,500/acre at KES 165/kg), but at Tana River's 53/100 suitability a realistic target here is closer to 1,656 kg/acre (~KES 273,240/acre) unless the constraints above are addressed.
