Hau Loc is a coastal plain district in Thanh Hoa province, with a favorable location for socioeconomic development. To meet the demands for enhancing the efficiency and sustainable use of the district's agricultural land resources, this study was conducted with the aim of assessing the current land use status and soil quality as a basis for proposing appropriate use solutions. GIS technology was used to overlay the 2022 land use status map with the 2012 soil map, combined with additional soil sampling to evaluate the current land use and soil quality. The research results showed that agricultural land accounts for 65.99% of the natural area. In which rice cultivation land occupies the largest area at 34.18% of the natural area, other types of land account for a small proportion of 4 - 5% and salt production land accounts for only 0.77%. The fluvisols occupies the largest area with 43.71% of the natural area and 64.41% of the agricultural usable land area, followed by the salic fluvisols with 11.56% and 17.03%, the acrisols with 6.72% and 9.89%, and the arenosols with 5.88% and 8.66%. The arenosols and acrisols have low fertility, poor water retention and low nutrient retention, requiring sufficient fertilization, physical property improvement, agroforestry models and reforestation. The salic fluvisols continues to maintain and develop sedge and specialty rice cultivation in existing areas and arranging brackish and saltwater aquaculture in low-lying areas, it is necessary to pay attention to irrigation solutions for fresh water supply, salt washing and salinity prevention. For the fluvisols, it is necessary to invest in intra-field traffic infrastructure, irrigation, balanced fertilization and appropriate crop structure to increase efficiency and protect the soil.Sâm thập tử (Decaschistia sp.) thuộc họ Malvaceae, là một loài dược liệu được người dân địa phương sử dụng làm thuốc do có hàm lượng dược liệu cao, khả năng bồi bổ sức khỏe, tăng cường sinh lực, chống suy nhược thần kinh.
