Learning outcomes

At the end of the course, the students can appreciate the value of the soil,  which is a not renovable resource. It knows the factors that lead the genesis and the development of soils. Students are 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, students 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. 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 reclamation and fertilization. The soils and Internet. Lows on soils.

Teaching methods

Power point presentations, practices in GIS and chemical laboratory, field trips.

Assessment methods

Assessment methods comprehend both a test and a presentation of one research and interview that will be addressed to verify the level of knowledge reached by the student, regarding in particular: soil importance and functions, soil forming factors, processes of soil formation and evolution, main horizons characteristics. Moreover, particular emphasis will be given to soil survey methodology and criteria, connected with the use of cartography and GIS. In addition the knowledge on soil sampling and chemical analysis techniques will be checked, and the use of analytical results in order to proceed to an evaluation of soil quality for its sustainable use.

Teaching tools

Video projector, GIS laboratory, chemical laboratory, field trip in several environs for observing pedological profiles and performing simple chemical tests
