Many practical classes and theses and dissertations of the Program require laboratory testing. Parts of these analyses are made in the very laboratories of the Department of Engineering. Other analyses are made in laboratories of other departments, such as the laboratories of the Department of Food Science and the foliar analysis laboratories and fertility of soils, in the Departments of Chemistry and Soil Sciences, respectively. In addition to the infrastructure of the University, distributed in its various departments and laboratories, the students of master’s and doctorate degrees in Agricultural Engineering count with a specific infrastructure for each area of concentration:
