Preparation of soil conditioners and characterization of their nutrient release kinetics
Horváthová, Lenka ; Jančář, Josef (referee) ; Lepcio, Petr (advisor)
This diploma thesis deals with the preparation of multifunctional soil conditioners based on potato starch, in order to slow down the release of nutrients. Materials with different contents of superabsorbent polymer and zeolite were prepared. Spectra indicating the formation of new bonds were evaluated by infrared spectroscopy. The kinetics of nutrient release were observed in the prepared samples of soil conditioners in an aqueous medium, where nutrient retention was demonstrated. Other samples were tested on plants, which proved a mostly positive effect on growth and other factors.

The influence of factors at produce starch of potato
ŠOBROVÁ, Martina
The thesis is focused on the factors influencing the production of starch potatoes. These factors include the influence of variety, seed, soil, stress, fertilization, climatic conditions and weather. The work also provides basic information about potatoes, the history of the potato and its importance, the use of potatoes, the biological characteristics, morphology and chemical composition of potatoes. There is also an evaluation of the economics for potato starch processing.
