Soil Fertility and Plant Nutrition

Base Knowledge

The student should have good knowledge of chemistry, biology and pedology. Ideally, for good student progression, must already have a positive performance in these UC.

Teaching Methodologies

To achieve  the objectives of each of the aspects focused on the curricular unit and  the competences foreseen to the students, the teaching-learning process is based on:

i) The study of specific cases, accompanied by a set of instructions that lead the student to analyze them, draw conclusions and make decisions or suggest actions; ii) In the execution of practical works for the application of theoretical concepts, which can be numerical, laboratory or field in nature; iii) In the necessary bibliographical research to complement the information obtained in the classes and for the execution of the reports.

Learning Results

For the student to complete the curricular unit successfully, he/she must acquire the following skills:

1. Know the behavior of nutrients in the soil-plant-atmosphere system and the importance of physical, chemical and biological soil fertility;

2. Carry out procedures to assess soil fertility and plant nutritional status, namely: a) Collect samples of soil and plant material; b) Know the methodologies used in the chemical analysis of soils and plants; c) Interpret the analysis results.

3. Draw up a fertilization plan suited to the organic production method

Program

I. Soil fertility and plant nutrition and study of the dynamics of plant nutrients in the soil and in the plant. Characterization of physical, chemical and biological soil fertility: physical, chemical and biological processes and reactions inherent to each of the processes.

II. Use of diagnostic methods: Collection of soil and plant material samples and soil and plant material analysis methodologies. Interpretation of results obtained in analytical determinations.

III. Characteristics of fertilizers in general. Fertilizers suitable for organic production. Principles used in general recommendations for fertilization and conversion to organic production. Fertilization plans suited to organic production standards

Grading Methods

Continuous evaluation

The evaluation is considered in two parts.

The conditions for success in continuous assessment are those provided for in the ESAC Student Performance Assessment Regulation, adding the fact that a minimum classification of 7 values is required in the written tests.

Part I: concepts related to Soil Fertility are taught, which should confer competence

Assessment by written test (TE) with a weight of 100%

Classification part I = TE

Part II: content related to Plant Nutrition and Fertilization is taught, which should confer competences 2 and 3.

The assessment instruments are:

  • written test (TE) (50%)
  • elaboration of a written work (Trab) with presentation and discussion of the work (50%).

Classification part II = 0.5xTE + 0.5xTrab

The final classification corresponds to the arithmetic average of the two parts.


Assessment in final exam

The conditions for success and the specific situations for which it is possible to carry out the evaluation by exam are those provided for in the ESAC Student Performance Assessment Regulation.

The student must take a written test that covers the syllabus of the curricular unit with marks distributed according to the relative weight of the different subjects, being approved if he obtains a minimum classification of 9.5 out of 20.
