Assessment methods and Criteria
Written examination of 1.5 hours, with questions and exercises on the entire programme of the part "Modelling for soil and crop management". The optimal length of an answer ranges from a few lines to a whole page written by hand, depending on the question or exercise. The mark is assigned by averaging the marks of each answer.
The written exam is supplemented by a final oral exam, which will begin with the discussion of a personal project of agronomic innovation on a topic agreed with the professors, and will continue with a verification of the contents of the teaching unit of Crop systems and supply chains. The mark will be recorded at the end of the oral exam.
The evaluation of both exams considers: a) the use of adequate language; b) the correctness of the contents; c) the completeness of the answers; d) critical thinking. Missing contents reduce the mark. Excess contents are not evaluated. In the exercises it is important to use the proper order of magnitude for the variables and the parameters. Units must always be specified. A pocket calculator can be used for the exercises in the written examination.
There will be at least:
· Two exam dates at the end of each semester (Jun-Jul, Jan-Feb)
· An exam date during the intermediate exams period (Apr, Nov)
· An exam date in September
How to study: a) participate to the lectures and the practicals; b) study your lecture notes, the slides, the papers and the books; c) revise the exercises done during the practicals; d) use the models in conditions other than those proposed during the practicals.
Students with SLD or disability certifications are kindly requested to contact the teacher at least 15 days before the date of the exam session to agree on individual exam requirements. In the email please make sure to add in cc the competent offices: [email protected] (for students with SLD) o [email protected] (for students with disability)

6. Model calibration and validation (0.5 ECTS).
Teaching methods
There will be:
(a) Lectures to present all the topics of the programme.
(b) Computer practicals to apply - using a spreadsheet - all the concepts learnt during the lectures. Development of a project on a case study to achieve a unifying point of view on the topics.
(c) Group discussions to stimulate active learning.
The practicals are very important. They consist in a practical application of the concepts presented during the lectures and therefore allow a better assimilation of all the concepts. Moreover, the orders of magnitude of variables and parameters can be easily grasped.
You are strongly invited not to study the concepts by heart. This will allow in the future to extend what you have learnt to other cases that are similar to those presented in this course, and to obtain a critical view. One way to do so is to read not only the lecture notes but also the articles and books that are suggested. Moreover, doing various exercises allows to verify that all the concepts are clear.

Teaching Resources
A textbook for this course does not exist. An accurate selection of book chapters, articles and web pages, together with the slides, is available on moodle. Most material is in English.
The material is the same for students who attend the classes and for students not attending.
The material is suggested for free consultation by the students; they are not used during lectures and practicals.
