Objective (expected results of study and acquired competences)

To know areas of problems and conflicts in protection of environment

and climate in agriculture, to point out causes of and solutions to

problems and conflicts. To know and evaluate the broad range of methods

of manure storage, treatment and spreading. To develop methods of

manure management with low nutrient losses, high nutrient efficiency

and low environmental impact. To apply guidelines on assessment of

emissions from animal husbandry. To describe methods of energy

production from energy plants and biomass (biogas production, solid

fuels, fuels).
