Learning objectives
Unit "Agrometeorology and crop ecology"
· Know and understand the differences between ecosystems and agro-ecosystems, and the specific characteristics of the latter.
· Know meteorological and agrometeorological variables.
· Know and understand the interactions between plants (and crops in particular) and atmosphere.
· Know the measurements methods of the main meteorological and agrometeorological variables.
Unit "Agronomy and weed control"
· Obtain an integrated view of factors that contribute to crop management and of crop utilisation in cropping system.
· Know and understand crop management techniques and their effects on productivity and environment.
· Know and understand the techniques to set up, manage and evaluate cropping systems in terms of productivity, sustainability and control of environmental impact.
Based on the basic disciplines of previous semesters, in this course the student knows and understands the interactions between crops and atmosphere and agronomic management techniques of cropping systems. This body of knowledge, integrated by more specific disciplines acquired later on, is a key tool to carry out a productive, environmental and economic evaluation of cropping systems.

Assessment methods and Criteria
There are two tests, one for each teaching unit. The overall mark is calculated out of thirty as the weighted average of the marks obtained in the two tests. It is communicated through the University platform for recording examination results and is officially recorded in such a way that it can be rejected.

Teaching unit: "Agrometeorology and Agricultural Ecology"
Knowledge and understanding of the topics covered will be assessed through a written test with closed-ended and open-ended questions lasting 1.5 hours. There will be no oral examination.
The test for the Agrometeorology module includes two multiple-choice questions, 2-3 open-ended questions, and one exercise.
Only the use of a calculator is allowed for carrying out the exercises.
There is no penalty for incorrect answers in the multiple-choice questions. The optimal length of the answer to the open-ended questions may vary from a few lines to a full handwritten page.
Assessment will be based on the following elements: (a) appropriate use of language; (b) accuracy of the content; (c) completeness of the answer. Missing content will lower the grade. In the exercises, it is important to choose the correct orders of magnitude for the variables and parameters involved; units of measurement must always be specified.
Part of the grade will be assigned through the assessment of group work, where applicable.
To pass the overall exam, students must achieve at least a passing grade in both the Agrometeorology module and the Agricultural Ecology module. If the student passes only one of the two modules, they may retake the test for the module that was not passed in a subsequent exam session.
The following exam sessions are scheduled:
· Two sessions at the end of the four-month teaching periods (June-July, January-February)
· A possible session during the mid-term tests (April, November)
· One session in September
The grade for the test will be communicated by email. Students are required to reply by email to accept the result.

Teaching unit: "Agronomy and Weed Science"
The test for this teaching unit is written and consists of a first part with 12 multiple-choice questions, contributing 25% of the score, and a second part with six open-ended questions, accounting for the remaining 75%. There is no penalty for incorrect answers in the multiple-choice questions. The optimal length of the answers to the open-ended questions, which may also include exercises, may range from a few lines to a full handwritten page. The duration of the test is two hours and twenty minutes.
The assessment, expressed out of thirty, is based on the following elements: (a) appropriate use of language; (b) correctness of the content; (c) completeness of the answer. Missing content lowers the mark. Extra content is not assessed. In the exercises, it is important to choose the correct orders of magnitude for the variables and parameters involved; units of measurement must always be specified.
The use of a calculator is permitted for the exercises. There is no oral examination.
Students who wish to do so may take part in individual and group activities during the semester. Upon submission, for each activity, of a written report that will be assessed, these activities allow students to obtain up to three points, which will be added to the mark of the written test. The activities are presented during the first lecture and are available on the course myAriel website.
Passing the optional mid-term test, held during the teaching break, allows students to take a shorter final test, lasting two hours, on the same content as the standard test.
The following examination sessions are scheduled:
· Two sessions at the end of the four-month teaching periods: June-July and January-February
· One session during the mid-term test periods: April and November
· One session in September
Students with specific learning disabilities or disabilities are kindly requested to contact the lecturer by email at least 15 days before the scheduled examination date in order to agree on any individualised measures. In the email addressed to the lecturer, the relevant University Services must be copied: [email protected] for students with specific learning disabilities, or [email protected] for students with disabilities.
There are no differences in the type of examination between attending and non-attending students.

The "agricultures of change" (Organic, integrated, regenerative, permaculture, syntropic, conservation agriculture, etc.) are the most important agricultural tools. Definitions and comparisons in the agroecological framework). Mitigation potentials of pollutant and greenhouse gas release reduction by the agri-food system (1 CFU)

Teaching methods
The course includes three teaching formats:
(a) Classroom lectures for the presentation and discussion of all the topics in the syllabus.
(b) Classroom practical sessions for hands-on activities, such as reading and discussing technical articles, and preparing the nutrient management plan and the humus balance.
(c) Educational visits to farms, during which students will be able to directly observe soils, crops, and equipment, and discuss concepts related to tillage, fertilization, and weed management in arable crops with farmers and technicians.
All these activities contribute to achieving the expected learning outcomes by encouraging reflection on the interconnections among soil, crop, management, and atmosphere. The classroom practical sessions contribute to the acquisition of techniques for preparing the nutrient management plan. The field practical sessions, namely the educational visits, make it possible to put into practice what has been learned during lectures and classroom exercises, through discussion with technicians and farmers.
