Farming practices for efficient use of nitrogen and reduction of its losses: Certified methodology for practice
Klír, Jan ; Haberle, Jan ; Růžek, Pavel ; Šimon, Tomáš ; Svoboda, Pavel
The methodology describes the main risks of nitrogen losses and recommended practices for their reduction. Practically applicable methods for the evaluation of the nitrate leaching risk depending on the soil, crop, root range, croping system, irrigation and weather conditions are described in detail. Consequently, suitable soil treatments and fertilization are proposed to improve the utilization of the nitrogen and uniformity of the water soaking.

How do the efficient portfolios at various investment horizons differ?
Růžek, Pavel ; Krištoufek, Ladislav (advisor) ; Křehlík, Tomáš (referee)
The Efficient Market Theory that assumes the homogeneity of investors' ex- pectations has several shortcomings and has failed to predict development of fi- nancial markets many times, recently. Previous research, therefore, has focused more intensively on incorporation of some aspects from Behavioural Finance to their models. This thesis implements another form of heterogeneity coming from different investment horizon preferences, and investigates the impacts on the selection of the efficient portfolios compared to the original Markowitz's framework. We employed the mean-variance model adjusted for the purpose of the work, and, additionally, suggested extensions that assure robustness of the model and the highest possible objectivity of the empirical results inde- pendently on the choice of data sets. The findings from our research strongly confirmed proposed hypotheses that the efficient portfolios do differ at the var- ious investment horizons and that the efficient portfolios for long investment horizons are less risky.
