SOIL FERTILITY AND PLANT NUTRION

The course aims to provide the students a general comprehension of the chemical-physical and bio-ecological properties of the soil and the plant biochemistry. The student at the end of the course will get the skills and the abilities to evaluate the soil fertility, from a chemical, physical and biological viewpoint, and implement strategies to manage it or to increase it according to the target of production fixed and/or environmental need.

Knowledge and understanding
The course will provide students with the necessary chemical and biochemical concepts to understand the functioning of the soil-plant system, as well as the metabolic processes that regulate life. In particular the student will learn:
- the molecular composition of ecosystems.
- the molecular basis of various biotic and abiotic processes that occur within.
- the mechanisms that regulate the availability of nutrients.

Applying knowledge and understanding
The course will enable students to:
- use soil characteristics, environmental conditions and plant characteristics to deduce nutrient availability for the plant.
- plan the necessary actions required to determine the soil properties of a agricultural farm.
- solve simple problems regarding the soil system.

Making judgements
The course will enable students to:
- critically assess and evaluate the physical, biological and chemical fertility of a farm's soils.
 
Communication skills
The course will enable students to:
- adopt appropriate scientific terminology when referring to the soil-plant systems.
- write a detailed professional report on the fertility characteristics of a soil.

The course is made of:

- Frontal lessons (21 hours) in which the student acquires the basis notions on the aspects of soil fertility and plant nutrition;

- Application part (56 hours)(laboratory exercitations and/or on field experience) by transferring the theoretical concepts to practical experiences by examples allowing the student to acquire greater mastery of the subject to complete the training process.

If teaching is given in a mixed formula or remotely, necessary changes may be introduced to what was previously stated in order to comply with the provided and reported Syllabus.

Learning assessment may also be carried out on line, should the conditions require it.

As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. 
It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professor Anna De Angelis.

Learning evaluation will be assessed by oral examinations. Checks in progress are foreseen in the mid of course to ascertain the learning level and the interest degree of the students.

Verification of learning can also be carried out by online way if it will be necessary.
