Learning outcomes

At the end of the course, the student has awareness of the value of the soil, which is a not renevable resource. It knows the factors that lead the genesis and the development of soils. The student is able to use the instruments and the methods in order to set up a pedological survey and to perform the main physical chemical analyses. Furthermore, the student will be able to classify soils, to interpret and to use the information in order to estimate the soil quality, in relation to the various land use destinations and to pressures to which soil can be subject.

Course contents

Pedology, soil, biogeochemical spheres, soils importance and functions. Ecosystem servicies. The soil forming factors: climate, bedrock, morphology, biotic factor, time. The processes of soil formation and evolution. The main surface horizons (epipedon) and depth horizons (endopedon). The set up of pedological survey: use of cartography, remote sensing and GIS for the identification of landscape units. The pedological survey: profile description, horizons sampling, laboratory analysis, results interpretation. Soil classification and cartography. The appraisal of soil quality, Land Capability Classification (LCC), Land Suitability Evaluation (LSE), Quality Indices (IQ). Soil phytoremediation and fertilization. The soils and Internet. Laws on soils.

Teaching methods

Power point presentations, practices in GIS and chemical laboratory, field trips. Depending on the evolution of the COVID 19 pandemic, lessons may be held in presence, at distance, or in a mixed mode.

Assessment methods

Verification of student learning will be done based on a pedological research that the student will present to the committee. The discussion that will open at the end of the presentation will be directed to the verification of the level of knowledge reached by the student, regarding in particular: importance and functions of soil, pedogenetic factors, processes of formation and evolution of soils, characteristics of the main pedogenetic horizons, soil and environment. In addition, particular emphasis will be given to the knowledge of methods and criteria of soil survey, connected with the use of cartographic and GIS tools. Moreover, during the discussion, knowledge of sampling methods and main laboratory analytical techniques will be tested, as well as the use of analytical results in order to reach an assessment of soil quality for its sustainable use.

Teaching tools

Video projector, GIS laboratory, chemical laboratory, drone, GPS, compass, field trip in several environs for observing pedological profiles and performing simple chemical tests. TEAMS, VIRTUALE and PANOPTO platforms will be used to support the teaching activity as repository of shared materials.
