Key words
soil, climate, water, ecology, integrated biological team project
Objectives
To gain an insight in the soil forming factors determining the genesis and spatial distribution of soils: climate, water, fauna and flora, parent materials. Major attention is also given to the mineralogical composition (mainly the clay minerals) and physical characteristics of soils as growing medium for plants.
Based on the gained knowledge from this course, as well as from the courses of botany and zoology, the students will carry out an integrated biological team project in a certain ecosystem in Belgium.
Topics
The first chapter of the course treats de structure with emphasis on the chemical and mineralogical composition of the earth crust. In the chapter on mineralogical composition, major attention is given to silicate minerals (clay minerals). The next chapter treats the soil forming factors and processes, with emphasis on parent materials (rocks) and occurrence in Belgium, landscape, climate (different climatic types), water cycle and biological factors (fauna and flora) (different ecosystems). Those factors will determine to a large extent the soil type and soil properties. Major attention is also given to the physical characteristics of soils (soil texture and structure, soil water and air, bulk density, …). The soil profile in relation to soil classification in Belgium and the distribution of the different soil types in Belgium are also discussed (last chapter).
Prerequisites
Basical knowledge of chemistry and physics required for interpretation of chemical and physical soil properties and processes.
Final Objectives
The course enables the student to interpret in a practical way the different soils in temperate regions (as Flanders, Belgium) and in different ecological systems and to evaluate those soils through their mineralogical, morphological and physical properties. A good knowledge of those properties is very important for a rational management of the soils.
Materials used

Teaching Methods
The theoretical part is given as lectures, in combination with field work during which the soil is studied in its natural context. The students must be able to implement the gained theoretical knowledge, i.e. characterize the soil and interpret the soil to its practical value.
For the ‘integrated biological team project’, a list of locations of diverse ecosystems will be available. Students are divided in study groups and will choose a ecosystem. The assignment of the team project will be the soil characterization, the survey (inventory) of the fauna and flora of the considered ecosystem and the investigation of interrelations between the observed properties, e.g. relation between soil and land use, relation between soil drainage conditions and fauna/flora,… The students will work autonomously in the field and consult different sources of information (library, internet, soil maps, vegetation maps, …). To stimulate the progress, coaching sessions will be organized mainly oriented to the integration of the knowledge on soil science, botanical and zoological science, .. of the considered ecosystem. Finally, each study group will write a report and present the data and conclusions.
