66030 - Soil Physics

Course Unit Page

Academic Year 2021/2022

Learning outcomes

At the end of the course, the student has acquired the knowledge of the physical and chemical principles that regulate the exchange of mass and energy in the soil, in the plant and in the first atmospheric boundary layer. The student is able to: measure the main physical variables of the soil, quantify the main terms of the water balance of crops through the use of mathematical models. The student has acquired skills related to the hydrostatic and hydrodynamic state of the soil, the thermal state, and the transport of solutes for the purpose of quantifying the fluxes of environmental pollutants.
