1. Forest Soil and Forest Soil Laboratory provide the core foundation for understanding forest environments. These courses help students establish basic concepts of forest environments, including the properties and chemical weathering of forest soils, mineral composition, water dynamics, nutrient elements, soil organic matter, soil organisms, and biochemistry.<br>2. Advanced Theory and Methodological Courses include Forest Ecohydrology and Forest Climate & Practice, which cover knowledge related to forest environment water and biogeochemistry. These courses establish the theoretical framework for the expertise module by studying biogeochemical mechanisms and analytical methods in physics, chemistry, and biology.<br>3. The Capstone Course, Introduction to Terrestrial Biogeochemistry, emphasizes advanced theoretical and analytical methods and highlights field surveys and laboratory instrument analysis. The instructors have extensive field survey experience. The course also introduces various forest survey and analysis instruments used in the department, providing students with practical techniques or methods related to the theoretical courses.
