88208 - SOIL FERTILITY AND PLANT BIOCHEMISTRY

Contenuti

Course Unit 1. Soil fertility (total 3 cfu). The student at the end of the course will get the ability to evaluate the soil fertility from a physical, chemical and biochemical viewpoint. Students shall be able to manage it and to increase it, if necessary, according to the target of production fixed and environmental aspects. Biogeochemical cycles. Nitrogen: fixation, mineralization, immobilization, organication, nitrification and denitrification. Phosphate: mineralization of the organic phosphorus. Sulphur: reduction of sulphate and oxidation of Sulphur. Potassium, Calcium, Magnesium and Iron. Fertilizers and factors affecting fertilizers uses. Criteria to assess nitrogen mineralization of organic fertilizers and amendments. Evaluation of the soil fertility. Organic farming. Recycling and use of biomasses of agro-industrial origin in agriculture.

Course Unit 2. Secondary metabolism of horticultural plants (total 3 numbers of credits). The course introduces into analysis and bioactivity of secondary plant metabolites. Different classes of bioactive substances will be covered. A practical part deals with the isolation, identification and quantification of natural components and testing the bioactive (mainly antioxidative) capacity of the isolated substances. Competence in advanced analytics of secondary metabolites from plants including extraction, identification of structures, quantification. Primary metabolism vs secondary metabolism. Function of secondary metabolites. The classes of secondary metabolites: Terpenes, Alkaloids, Phenols. Biosynthesis of terpenoids. Biosynthesis of phenols or shikimate pathway. Analytical methods: Principle of Spectroscopy (IR and Raman). Principle of Chromatography (GC, HPLC).

Metodi didattici

The course consists of lectures (36 hours) and practices (24 hours) represented by seminars offered by visiting professors from other institutions, to integrate the instructor's lectures.

Modalità di verifica e valutazione dell'apprendimento

Final  exam is a seminar on an argument related to a specific topic of both unit course. The duration of the presentation is estimated at around 30 minutes. The final grade is assigned based on the degree of preparation of the student and especially about its capabilities and critical connection between different subjects
