Abstract: [slo] [eng]
Táto diplomová práca sa zaoberá prípravou multifunkčných pôdnych kondicionérov na báze zemiakového škrobu, za účelom spomaliť uvoľňovanie živín. Boli pripravené materiály s rôznym obsahom superabsorpčného polyméru a zeolitu. Pomocou infračervenej spektroskopie boli vyhodnotené spektrá, ktoré naznačujú vznik nových väzieb. U pripravených vzoriek pôdnych kondicionérov bola pozorovaná kinetika uvoľňovania živín vo vodnom prostredí, kde sa preukázalo zadržiavanie živín. Iné vzorky zas boli testované na rastlinách, kde sa preukázal zväčša pozitívny vplyv na rast a iné faktory. 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.
