The course aims to provide the students the necessary tools for the comprehension of the plant responses to the different soil conditions. In particular, the dynamics related to the rhizosphere will be deepened trough the comprehension of the metabolic processes involved in the stress response.
The course is made of 42 hours of frontal lessons in which the student will acquire the basis notions on the aspects of soil fertility and plant nutrition.
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Learning assessment may also be carried out on line, should the conditions require it.
