Možnosti uplatnění minimalizačních technologií zpracovaní půdy v zemědělském podniku
Poláček, Tomáš
Appropriate soil treatment has an impact on soil water management. It also affects the time requirements of field operations.. The agricultural company LEDEKO, a.s. was selected to carry out the work. The research part of the thesis deals with soil, minimization of soil tillage and cross compliance, which is tied to soil tillage. Subsequently, the farm is described – cultivated crops and methods of soil cultivation in the preparation of the establishment of these stands. Based on this information, no tillage for maize and other cereal crops, or strip tillage for maize, was proposed. The use of the same seed drill as for maize was proposed for rapeseed cultivation. The advantage of these systems is mainly time saving.

Vyhodnocení ztráty půdy vodní erozí ve vybraném území
Teplý, Lukáš
Diploma thesis deals with the evaluation of threats on agriculture land by water erosion in the cadastral area of village Čikov before and after proposing of counter – erosion measures. For the calculation of erosion was used Universal equation (USLE) according to Wischmeier and Smith. The analytical operations leading to the calculation individual factors Universal equation and average long-term loss of soil by water erosion were made using the software ArcGIS, USLE2D and LS – Converter. Partial analysis are presented in the form of map outputs. In the interest area, after the calculating of the USLE, it was found that on 30,39 ha occurs very strong erosion which represents 4,73 % of the solved area. Strong erosion occurs on 36,56 ha (5,68 %), medium erosion on 229,94 ha (35,75 %) and slight erosion on 346,33 ha (53,84 %). Thanks to the proposed counter – erosion measures, very strong erosion in the interest area was completely eliminated. Strong erosion was reduced to only 2,52 ha (0,39 %) and medium erosion to 74,79 ha (11,58 %). Slight erosion increased to 566,21 ha (88,03 %).

Environmentální dopady pěstování energetických plodin
Pospíšilová, Jana
The presented thesis is written in a literary review and addresses the issue of energy crops and their impacts on the environment. Intensive field crops cultivation has an adverse effect- increase susceptibility of soils to erosion, overuse of pesticides and fertilizers, eutrophication and soil compaction. Partial objective is a description of possible remedies to these influences. The thesis describes fytomass processing technology, the characteristics of selected field crops, related legislation, including checks on compliance, whose job it is to motivate farmers to the proper use of land. Because only soil and water protection can provide the sustaiability of agriculture.

Evaluation of erosion control measures described in GAEC II by using hydrological modeling
HRDINA, Filip
Erosion is an issue, which causes huge damages not only on agricultural land. This diploma thesis describes practical evaluation of erosion control measures (usage of leaving crop residue, circuit strips, contour tillage), which are include in Good Agriculture and Environmental Condition standart, which was issued by European union. Efficiency of usage of narrow-row and wide-row crops is also modeled. Each measures were evaluated in two different modeling programmes HydroCad for calibration and ERCN for results comparison. Seven different scripts are used in the thesis. Subcatchment area P6 in catchment area of Kopaninský creek is used as model area. Literature review describes the precipitation and runoff process, issue of erosion, and agriculture land protection against water erosion. Is also describes GAEC standards (today DZES).
