Different type of biomass parcels after the harvest as a microbiotope for invertebrates
 MACHOVEC, Jiří
Epigeic beetle communities were studied on four types of biomass bales in the cadastral unit Vrbice u Žitné, district Prachatice. Involved were bales a of grass silage stored on the edge of permanent grassland, on hay bales individually placed on permanent grassland , followed by straw bales scattered in the fields of arable land and straw bales stored on the edge of arable land. The first three types of bales were in position only few months (2-3), while straw bales at the fourth position had been more than one year. The sampling method was selected a sieving of detritus. In the bales of hay were found 9 species of 5 families. In hay bales were found 7 species of 4 families. In the straw bales (which spent in position less time - 3 months), were found 10 species of 6 families. In the bales which were in position 13 months, were found 14 species of 4 families. Index of anthropogenic influence on communities demonstrated that the positions are strongly influenced.

Comparison of pick-up balers Pottinger, Rollprofi 3200 LSC and Krone KR 10-16S during the harvested production.
 MACHOVEC, Jiří
This bachelor work is focused on evaluation of round balers. It is about comparsion of machines from major producers of harvest equipment Krone and Pöttinger. The goal was to find out qualitative and quantitative differences between round baler Pöttinger Rollprofi 3200 LSC with fixed compression chamber and Krone KR 10-16s with variable compression chamber. It was evaluated performance, forage quality, cutting quality, the measure of copressibility and economic indicators. The result was a finding, that in terms of quality of work, both machines are comparable. The differences are in purchase costs of machines, as a result of higher fixed costs of pick-up baler Krone KR 10-16s. Next differences appears, when different diameters of bales are needed. Then a pick-up baler with variable compression chamber must be used.
