Abstract
This study evaluates the soil texture and nutrient content of coastal mangrove areas in Quynh Luu, Dien Chau, and Nghi Loc districts, Nghe An province, to restore lost mangrove areas. Two sampling and analysis phases reveal that the soil texture primarily consists of sand with silt and clay additives. Silty sand occurs at all study sites with pH ranging from 5.2 to 8.6 and the bulk density from 0.4 to 0.61 g·cm–3. The Lach Quen River, Lach Van River, and Lam River estuaries have a higher content of OM, T-P and T-N than other coastal areas. The highest concentration of T-P recorded at the Lach Van River estuary was 231.1 mg·kg–1, and the T-N at the Lam River estuary was 575.3 mg·kg–1.
