The course aims at providing students with specific and deepened knowledge and comprehension capacity regarding plant productions to design and manage the innovation of agriculture production, from both qualitative and quantitative point of view, focused on a systemic approach to the soil quality, sustainable cultivations, and environmental impact. The main objective of the course is the understanding of the agricultural practices within circular productive processes for the valorization of waste products such as nutrients and bioactivators for the cultivations.

The final exam consists of an oral interview (ca. 30 min of duration; generally 3 questions) on the topics developed during the course and will aim to ascertain both the concepts learned and the ability to link them and discuss implications. The exam method is the same for attending and non-attending students.
