LauZ3139, Soil Fertility and Fertilizers

Course abstract

Raw materials for the production of commercial fertilizers, their characterization and resources. Technology of production, economic and ecological aspects. Trends in the production and use of commercial fertilizers. Characterization and use of nitrogen, phosphorus, potassium, micronutrient and multinutrient fertilizers. Organic fertilizers, production, handling and use. Technology of fertilizer handling and use, agronomic, economic and ecological aspects. Segments of fertilization system, their optimization. Specifics of fertilizer use for field crops, horticultural crops, in greenhouses.

Learning outcomes and their assessment

Students will get an extended knowledge about fertilizers, its use and fertilizer planning. Students will obtain skills how to adjust the fertilizer practice according to crops’ biology and growing technologies. Students will understand the importance of agronomical and meteorological factors on plant nutrition. As a result student will be competent to manage agronomical issues of fertilizer planning, to work as an advisor, to carry out research as well as to analyse and prepare scientific publications.
