Educational objectives
Pedology:
The course takes into consideration the basic elements which constitute the soil resource and its functioning. The main objective is to provide the
students with all the elements to manage the soil in a sustainable way. The main acquired knowledge will be: factors of soil formation, chemical
and physical alteration of minerals, role of soil biota, soil organic matter cycle, pedogenetic processes, soil degradation processes.
At the end of the course the students should be able to recognize a soil type, and to interpret the morphological and analytical information useful to evaluate the soil quality and the environmental sustainability of a given soil use.

Environmental and Agricultural Chemistry:
To know the impact of fertilisers and pesticides on the soil system
To know the impact of fertilisers and pesticides on the water system
To know the rules for pesticides utilisation
To know the possible use of waste-deriving fertilisers
To know the impact of waste-deriving fertilisers on the soil system
To know the impact of sewage sludge on the soil system
To calculate the Predicted environmental concentrations (PEC) of pesticides in soil, surface water and groundwater.
Prerequisites

Extended program
Pedology:
Role of the soil in the natural and anthropic environment; Name and description of the soil horizons; Factors of soil formation; Physical and chemical weathering; alteration and evolution of the soils; proton-donors theory. Soil physical properties (texture, structure and porosity), air and water in soil; Soil mineralogy; Characteristics and dynamic of the soil organic matter; Principal pedogenetic processes; Soil degradation processes; Soil and climate change.

Environmental and Agricultural Chemistry:
Soil fertility and fertilizers; Soil organic amendment: the rule, the production, the quality and the risk assessment. Composting of urban and agricultural wastes. Biogas production and the use in the agriculture of digestate. The integrated anaerobic/aerobic treatment of waste. The agricultural use of sewage sludge; Agricultural use of animal manures: treatment and management.
Risk assessment for surface water and groundwater due to the use of pesticides. The behavior of pesticide in the soil.
Practices: Agronomical and environmental quality parameters of fertilizers; PEC soil, PEC surface water and PEC groundwater determinations.
