Cilj predmeta: The aim of the course is to provide the student with basic knowledge about the most important and complex component of the forest ecosystem. Furthermore, the goal is to prepare the student for the acquisition of new knowledge necessary for the management of the forest ecosystem, especially with regard to its stability and protection from degradation processes. Therefore, the goal is for students to learn how soil is formed - what are the factors and processes of its formation, what are the key processes that take place in it, and what are the physical, chemical, biological and morphological characteristics of soil
