- Particles organization or (micro) structure
- (genesis, morphology, porous resultant, sensitivity, appropriated characterizations).
- Liquid and gaseous phases :
- water in the soil (characteristics, behaviour, incidences);
- soil air, oxydo-reduction potential and soil temperature.
- Colloïdal properties and soil solution.
- Acidity and alkalinity.
- (Bio)availability in (micro)nutrients.
- Outline for soil fertility assessment.
- Basics of soil physics

Learning outcomes of the course :
|
| To portray soil as an organized, living and dynamic system (soil as a reactor); the comprehension of which (or pedological synthesis) being essential for all uses aiming at sustainability, reversibility and respect for the environment.
After completing the course the student is expected to
- grasp the causes-effects relationships between soil compounds, properties and behaviours
- draw the main criteria of the pedological diagnosis,
- deduce the main practical incidences for soil management,
- decrypt/encrypt soil profiles and soil types according to horizon codification and the legend of the Belgian soil map,
- treat of main world soil types in a structured way.
- understand the complex interplay between soil and plant with a focus on water and nutrients
After completing the course, the student will be skilled to
- describe a problem of environmental management and identify the scientific and technical questions it implies as well as the data necessary to solve them.
