| Course contents : | Soil as an environmental factor - general concepts introducing the profile definition.
The notion of parental material in comparison with forms and formations-supports (origin, nature, deposition).
Elements of identification :
- criteria of differenciation and horizon symbols;
- presentation of the Belgian soil map;
- main soil types of the world.
Field identification (2x 1/2 day early in the programme).
Solid components :
- mineral (granulometry, composition);
- organic - living and dead (morphology, determination, evolution).
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. |

| Course objective : | 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,
- descrypt/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. |
