Key words
tectonics, mineralogy, petrography, pedology, soil management
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.
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), watercycle and biological factors (fauna and flora). 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
Lecture notes ‘Bodemkunde’ (G. Baert), in Dutch
Textsbooks and interactive software available in the Laboratory.
Study costs
Cost: 15.0 EUR
15 euro
Study guidance
Permanent possibility for questioning, guidance and coaching.
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.
