Interakce mezi vybranými fyzikálními a chemickými půdními vlastnostmi v krajinném měřítku: detailní studie lokality Rudice na základě cíleného postižení prostorové heterogenity půdy v krajině
Vichta, Tomáš
In this bachelor thesis are assessed specified interacting physical and chemical soil properties of two main ecosystems (forest ecosystem, permanent grassland ecosystem) and their ecotone. Specifically, the detected soil properties, was determined by active soil reaction, soil reaction potential exchangeable, oxidizable carbon, total nitrogen, maximum capillary water capacity and minimum air capacity. For researches were chosen heterogeneous research area Rudice at TFE Křtiny Ml, the region of the Drahanska highland. In the work was used data obtained from spring 2016 (April), which has been then compared with data from autumn 2016 (October) and subsequently with each other, from physico-chemical point of view. Has been found that between some soil properties there was a change of values in two sampling dates and has been proved some certain correlation relationships between specified soil properties in permanent grassland ecosystem.

This diploma thesis deals with the water regime of soils of the forest landscape segment. The object of the research was the permanent study plot Ušákov with low forest (simple coppice) and high forest (abandoned simple coppices) at the Training Forest Enterprise Masaryk Forest Krtiny, Bilovice forest district. The main aim of the thesis is to evaluate the dynamics of the soil water regime during the hydrological year 2018 in this landscape segment in relation to the thinning (basal area of each polycormon was reduced to 50%) and 30% reduction of throughfall precipitation in coppice stand and also in relation to the different forest management. The results show that in the thinned coppice stands is soil moisture higher during the whole investigated season, while in the coppice stands with reduced throughfall is lower, the effect of the different forest management on the soil moisture was not conclusively proved. Another task of this thesis is also to introduce the basic outline of the methodology of how to evaluate continually and ambulatory acquired soil water regime data from any landscape segment. Based on this method, individual humidity values of the studied soils were analyzed.

The most pronounced increase in number of herb species was remarked in the clear cut+litter gathering treatment. Harvest led to an increase in soil temperature and moisture. TheCO2efflux was the highest in September, namely in control treatment. The lowest intensity of root growth was remarked in the control treatment. Variants with litter gathering had smaller (28.9%) relative growth ratio.
