Learning outcomes
At the end of the course, the student acquires the basic knowledge of the soil formation, factors of pedogenesis and world distribution of soils, with special focus on the climate-rock-biota system. The student will be able to: recognise the main types of soil and the features of soil surface horizons by field and analytical tools; evaluate the degree of soil development in the different environmental contexts; understand the relation soil-landscape.
Course contents
The student who accesses this teaching is in possession of a good preparation in the fundamentals of mathematics, chemistry and plant biology. These prerequisites are provided by the teachings of the first year of the degree.
Theoretical content of the teaching unit (total teaching unit: 21 hours)
1. Basic concepts
The soil, factors of pedogenesis, formation and evolution of soil, state factors and factorial Jenny's model, pedofunction and pedosequence
2. Factors of pedogenesis: climate
temperature and precipitation, thermo-pluviometric coefficients and diagrams, soil moisture and soil temperature regimes
3. Factors of pedogenesis: soil parent material
classification of soil minerals and parent materials, physical and chemical weathering, intensity of rock transformation, rocks chemistry and its effects on soil
4. Factors of pedogenesis: biota
Soil biomass, soil organic matter and its trasformations, classification of humus and its ecological significance, formation of surface horizons
5. Pedogenetic processes
Soil evolution and state of soil, processes of trasformation of material within soil, traslocation within soil, addition to soil and loss from soil, environmental contextes and main pedogenetic processes
6. Main soil types and their distribution
Main soil types properties according to the international soil classification systems and their worldwide and national distribution
The student will acquire skills related to the knowledge of the role and effect of the main factors of pedogenesis on soil, main processes of soil formation, and main properties of different soil types, in order to understand the relation between landscape and soil evolution
Pratical content of the teaching unit (tatal teaching unit 9 hours)
The pratical exercises are: determination of the main soil characterists (laboratory exercises: texture, soil pH, carbonate, soil organic matter, etc. etc.) and soil description (field exercises). The laboratory and field activities will allow a fast trasfer of knowledge presented in class into pratical applications necessary for understanding soil-landscape units. The practical exercises will be in collaboration with Chimica Agraria.
Readings/Bibliography
Fundamental will be the use of material provided by the teacher (available on AlmaDL) and lecture notes.

Chapters 1, 2, 3, 4, 5, 6 and 7 (Ch. 7 only the paragraphs concern on the moisture and temperature soil regimes)

Teaching methods
The course consists of lectures and pratical exercises in the laboratory and in the field. The slides of lectures will be available on AlmaDL.
Assessment methods
The course is part of the integrated corse "Chimica Agraria con Elementi di Geopedologia". Therefore, the final oral examination will assess the level of knowledge and skills acquired by the student concerning the contents of lectures of the 3 teachings (soil chemistry, biochemistry and geopedology). Students who have earned at least 18/30 for each teaching will be positively evaluated and the final grade will be the mean value of all teaching grades. The duration or the oral test will be an average of 45 minutes.
