08147 - Agricultural Chemistry

Learning outcomes

At the end of the course, the student will be able to understand the main chemical and biochemical processes of the soil-plant compartments and will also acquire basic knowledge of soil fertility and how it should be assessed and preserved

Course contents

Course Unit 1. Elements of Agricultural Biochemistry (total 30 hours).

Soil fertility index

Mineral and organic fertilizers

Readings/Bibliography

The materials presented during the lessons do not substitute the reference textbooks but are a complement to them. They constitute a guide for the selection and understanding of the topics to be dealt with. The reference texts are::

J.M Berg, J.L. Tymoczko, L. Stryer Biochimica. Zanichelli, 2012

P. Violante. Chimica e fertilità del suolo. Edagricole, 2013

P. Sequi, C. Ciavatta, T. Miano. Fondamenti di Chmica del Suolo. Patron Editore 2017. 

Students who wish to make the oral exam in English can use the following textbook:

D.L. Sparks. Environmental soil chemistry. Academic Press, 2003

J. M. Chesworth, T. Stuchbury, J.R. Scaife. An introduction to agricultural biochemistry. Chapman & Hall, 1998

Teaching methods

The course consists of lectures (40hours) and practices (20 hours) represented by seminars offered by visiting professors from other institutions, to integrate the instructor's lectures

Assessment methods

The evaluation of the course takes into account jointly the level of knowledge and skills acquired by the student in relation to the contents of Biochemistry and Soil fertility.

For this course, the skills will be assessed through a final oral examination, consisting of 2 questions.

The duration of the oral examination is estimated at around 20-30 minutes. 

The final mark is calculated as the arithmetic mean of the marks achieved in the Soil Chemistry and Agronomy Modules.

Students that wish to take the exam in English must request it from the teacher at least two days before the exam.
