In the work we present the results of an investigation which carried out in beech stands in the Kremnické vrchy and Štiavnické vrchy Mts in the year 2007. Five experimental plots were established in stands of the forest type group Fagetum pauper superiora, in different phases of their development. We observed energy and ash content in aboveground phytomass of Rubus hirtus species. We have reco ...

Application of bioindicatiors at Štěpánovice landfill

Vaverková, M., Mendel University of Agriculture and Forestry et al. [2009]

The study is focused on examination and determination of bioindicatiors, mainly phytoindicators. From their existence, condition or behavior judgements might be carried out on existence of specific environmental indicators and on environmental condition and changes. The goal of this study is to examine the conditions of ecological load (forest and meadow ecosystem)of Štěpánovice landfill.

The paper is focused on monitoring the soil properties in agriculture and forestry. Specific conditions for work of mobile equipment and specific requirements of the environment require different types of test equipment for measuring. To detect the status of soil are currently used penetration, shear and simulation testers, which are based on a principle of different soil measurements. Using o ...

The productivity of the harvester UTC F1067 in spruce stands

Dvořák, J., Czech Agricultural University [2009]

The aid of this study is the monitoring of the operation time and shift time of the wheel harvester UTC F1067. The chronometry was analyzed during the felling works in premature forest stands. This paper is worked up for tree-volume of coniferous species from 0.13 to 0.52 m3/tree. Total standards lies for premature fellings within the interval 0.09 - 0.18 working hours/m3 and the productivity ...
