Mulching is an effective method for stabilizing sand dunes and supporting afforestation and desertification control projects. Oil mulch enhances soil quality by adding essential minerals and increasing soil porosity, which improves water infiltration and retention. It also helps maintain soil moisture by preventing rapid evaporation. By creating a sticky layer on the soil surface, oil mulch stops the movement of sand dunes and creates favorable conditions for plant growth. Additionally, it stabilizes soil temperature, delaying the freezing of plant seeds in winter. This article examines the positive effects of oil mulch on soil quality, plant growth, and sand dune stabilization.
