The objectives of the course of Agronomy are those of providing the students with the tools to understand and critically assess the functioning and the management of the agroecosystem and have an understanding of the expected effect on the system of the principal components of the typical husbandry pattern of arable and horticultural cropping systems. The course is structured into two parts. In the first part the functioning of the agroecosystem is analyzed, with the aim of providing a basic knowledge of the main aspects of the biophysical factors of the system, i.e. those related to climate, soil and water. In the second part, the operations typically carried out for the management of the agroecosystem are analyzed e.g. soil tillage, irrigation, fertilization, crop sequence and weed management.
