(syllabus)
- Basis of pedology: pedogenetic processes, soil profile and genetic horizons, classification of forest humus
- International classification of soils (WRB): the diagnostic horizons, the properties and diagnostic materials, the reference groups (Reference Soil Groups), use of the WRB keys for the classification of soils
- Elements of soil physics: concepts and methods of measurement of texture, structure, bulk density, compaction, erodibility
- Water-soil relationship: water flows in the soil, water retention curves, field capacity, wilting point, available water (AWC), infiltration and permeability of soils, waterlogging and associated pedogenetic forms. Measurement and monitoring of water content and water tension in the field.
- Soil threats and degradation. Desertification
- Water and wind erosion of the soil. Analysis of the causes and effects produced, predisposing factors. Data and measurements of erosion in Italy and around the world. Main models for estimating water erosion (USLE, RUSLE)
- Landscape and landforms comprehension: references to geomorphology, forms of slope and valley deposits, glacial and periglacial forms, cariscal forms, structural forms. Photointerpretation, digital terrain models. The physiographic units.
- Pedological mapping: Soil-landscape paradigm; pedo-landscape hierarchy. Taxonomic units and cartographic units - Criteria for defining cartographic units - The series, type, phase, variants - The composite cartographic units - Associations, complexes - Mapping units in small-scale surveys. Organization of work for soil survey and mapping
- Principles of Land Evaluation: Land Capability (land use capacity) and Land Suitability concepts. Land capability classification for forestry
- Forest soils in the world and the main threats: effects of forest fires; effects of global warming on cryosols and histosols in tundra and alpine environments; land use change effects in soils with soft epipedon in steppe and prairie environments; effects of deforestation on tropical and sub-tropical soils.
- Forest soils as historical archive of climate and past management: Reading of past pedogenetic processes of soil characteristics that indicate a particular event
- From soil assessment to conservation and restoration: Principles and techniques of forest soil maintenance. Erosion protection after forest fires. Soil restoration operations after excavations and infrastructural works
