Growing Garlic in Tana River
Soil suitability analysis based on Tana River's nutrient profile
Possible but challenging — Tana River is only marginally suited to Garlic. Tana River's soil (pH 6.4, slightly acidic) gives Garlic a suitability score of 51/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.
Garlic can be grown in Tana River County, but the soil scores 51/100 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 Garlic 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. The county's predominantly sandy soils suit Garlic, which favours sandy loam. Garlic's full potential is about 3,000 kg/acre (~KES 825,000/acre at KES 275/kg), but at Tana River's 51/100 suitability a realistic target here is closer to 1,912 kg/acre (~KES 525,800/acre) unless the constraints above are addressed.
