Abstract
This study is a survey research that aims to characterize and classify coastal peat soils in the conservation forest located in Sidomulyo Village, Bilah Hilir Subdistrict, Labuhanbatu District. Soil analysis was carried out at the Research and Technology Laboratory of the Faculty of Agriculture, Universitas Sumatera Utara. The observations were carried out by drilling the peat soil using an Eijkelkamp drill with 3 depth layers of peat soil, then the morphology and chemical properties of the soil were observed and classified according to the Key to Soil Taxonomy, 2014. The results showed that the ash content in the surface layer was higher than the deeper layers, but pH, C-organic, EC and CEC were not much different at all layers. Based on soil taxonomic, peat in the study area is Hydric Haplohemist for sub group category.
