Teaching language

Suitable for English-speaking students

Objectives

It is intended that students acquire a solid knowledge about the mineral nutrition of higher plants, as well as fundamental knowledge about plant nutrients regarding the mechanism of absorption, mobility, function, and symptoms of deficiency and toxicity. It is also a goal to provide knowledge about the availability of nutrients for the plant, changes undergone and the balance of inputs and outputs of the soil-plant system.

Learning outcomes and competences

Upon completion of the course, students should be able to:

- Recognize the essential elements for plant growth, absorption mechanisms, mobility, function and deficiency, and toxicity symptoms.

- Explain the short- and long-distance transport of mineral elements.

- Understand how plant roots acquire mineral nutrients from the soil and how roots can modify properties at the rhizosphere.

- Recognize the most important factors influencing root growth in the context of nutrient acquisition.

- Show knowledge about the effects of nutrition on crop production.

- Show knowledge about fertilizers.

The students should develop the skills needed for the implementation, and analysis of results derived from the use of techniques in Plant Nutrition.

Program

Theoretical program

• Definition and classification of nutrients
• Soil-plant relationships: the soil as the mail nutrient medium source
• Nutrients availability and movement into the soil
• Effect of external and internal factors on growth root and development
• Rhizosphere chemistry and biology in relation to plant nutrition
• Absorption, assimilation, and transport of nutrients
• Assimilation of mineral nutrients
• Macronutrients and micronutrients in plants: function and symptoms of deficiency and toxicity
• Diagnosis of deficiency and toxicity of nutrients
• Nutrients and plant production
• Fertilizers and correctives

Laboratory program

Sampling and sample soil preparation; Physical properties of the soil; Soil reaction; Soil organic matter determination; Biochemical assessment of nutritional deficiencies and toxicity; Rhizosphere's pH variations as a result of the nitrogen source supplied.

Comments from the literature

The recommended bibliography is available at the FCUP Central library (ed. FC1). Complementary elements of study will also be made available by the teachers of the curricular unit.

Teaching methods and learning activities

Lectures and laboratory classes. Lectures are presented in a slideshow using the software "PowerPoint". The theoretical classes will be mainly expositive, although the students are encouraged to participate through a discussion component. The presentation of the material will be accompanied by the projection of images and diagrams that conveniently illustrate the oral presentation. The accompaniment of the subject of the theoretical classes should be done through bibliography: textbooks, websites and scientific articles.

In relation to the practical classes will be provided to the students a "Guide to support the practical work" containing the experimental procedures and which will also include the program and the schedule of the respective classes. Practical classes are compulsory.

Eligibility for exams

Terms of frequency: Attendance of lectures non-compulsory. Practical classes compulsory with absence limit of 25% of scheduled classes. (https://sigarra.up.pt/up/LEGISLACAO_GERAL.ver_legislacao?p_nr=4025).

Working students are not required to attend practical classes but will have to take a complementary practical exam in order to demonstrate that they have the knowledge and skills required at the UC.

Calculation formula of final grade

Students may choose to be evaluated by one of the following methods:

1) Final Exam-based evaluation or 2)Frequencies-based evaluation

1) Final Exam-based evaluation: final exam: covering theory (T) 20 points, and practical subjects (TP)  20 points

Final Grade: (2T+1TP)/3)

Minimum grade requirement in each exam (T and TP) - 8 points

2) Test-based evaluation

Test 1 (T1 = 20 points) and Test 2 (T2 = 20 points) covering theory subject only.

Grade of practical test (TP = 20 points).

Theoretical Final Grade (T) = [(T1 + T2)/2]

Final Grade:(2T +TP)/3

Minimum grade requirement in each test (T1 and T2): 8 points
Minimum grade requirement in TP test - 8 points


Approval: final classification equal to or greater than 9.5 points

Special assessment (TE, DA, ...)

If working students do not attend practical classes, they will have to take a complementary practical exame in order to demonstrate that they have the knowledge and skills required at the UC.

Classification improvement

To improve the final grade the student needs to request a new final exam, in accordance with current legislation on the subject.
