Soil Chemistry and Fertility

Semester 1 · 40190 · Bachelor in Agricultural, Food and Mountain Environmental Sciences · 6CP · DE


The course provides an introduction to the fundamentals of soil chemistry. Topics include soils as natural bodies and soil formation, inorganic and organic components, weathering processes, as well as the properties of soil water, soil air, and the soil solution. Key chemical processes such as sorption, ion exchange, buffering, and redox reactions are discussed. The course also covers soil fertility, nutrients, fertilizers, and soil amendments, alongside methods of soil sampling and analysis. Finally, attention is given to the rhizosphere as the interface between soil and plants.
