Abstract:

V poslední době se pozornost polečnosti obrátila k mikroplastům. Jsou produkovány různými odvětvími a šíří se napříč prostředím. Po dlouhou dobu byly považovány za inertní, bez dalšího vlivu na rostliny a jiné živé organismy, avšak jak zjistily nedávné studie, mohly by představovat vážnou hrozbu. Několik vědců, včetně nás, se proto začalo soustředit na jejich transport a transformace v životním prostředí. Většina se však zaměřuje pouze na jejich přítomnost v mořských a sladkých vodách, a proto jejich chování ve vzduchu a půdě zůstává nejasné. Kromě toho byla pozornost soustředěna i na bioplast

Abstract:

The main aim of the dissertation is to quantify changes in agricultural land use and propose some solutions to reduce or compensate for quantitative and qualitative degradation of the agricultural land resources in the Czech Republic. Data (WTO, FAO, CIMSC, RISWC, CSO, FADN) are processed by the geographic associations index, environmental stability index, regression and correlation analysis and multi criteria analysis. The quality of the agricultural land is decreased in southern Moravia and central Bohemia (Voltr, 2012). The quality farmland is mainly reduced in agriculturally valuable soil

Diploma thesis evaluates quality and healthiness of the soil health located close to Bohate Malkovice focusing on changes in both physical and chemical characteristics of the soil in time. The theoretical part describes physical, chemical, and biological parameters of the soil. Selected physical parameters are structure, texture, determination of measured weight, bulk density of the soil, porosity, actual volumetric water content of the soil, aeration, saturated and unsaturated hydraulic conductivity, infiltration, and colour. Chosen chemical parameters are pH, carbonates, soil electrical cond

Abstract:

Erosion is a global problem, which threatens one of the most valuable natural riches of the world, the soil. Erosion is a natural process that has been existing since the very be-ginning; this process is characterized by eroding the soil surface, transporting the soil particles, and the subsequent sedimentation of these particles. In its natural form, ero-sion does not present a big problem, since there are small losses of soil particles, which are sufficiently completed by newly formed particles from the subsoil. The real problem is identified in accelerated erosion which is caused by envir

Abstract:

This dissertation is dedicated to the issues of agricultural soil sealing and assessing erosion processes in the South Moravian region. The research uses statistical, raster and vector data. All data was processed and assessed using the methods of mathematical statistics. ArcGIS methods and approaches were used to process data, create mapping outputs and compare information on agricultural soil sealing and the threat of erosion. The results suggest that considerably large expanses, given the sizes of the locations under scrutiny, were sealed in all locations between the year 1824 and the prese

Abstract:

Soil crediting in the Czech Republic is based on so-called land boned soil-ecological units (BPEJ), this unit serves to evaluate both absolute and relative production capacity of agricultural land. The thesis points out the need to update this system, caused mainly by climate change, which causes the shift of the existing climate regions but also the emergence of new (not yet classified) climate regions. These changes have a direct impact on soil production capacity. In the thesis there is an overview of legal regulations that are influenced by the system of certified soil-ecological units (BP

Abstract:

Good soil condition belongs to the basic requirements of well-ballanced environment. That is why the soil has to correspond to hygienic requirements and be protected against substances harmful to human health, e.g. toxic materials, germs of transmissible illnesses and parasites. The most common cause of soil contamination is anthropogenic incidence. Contaminated soil belongs to waste and has to be removed in a proper way. is A special way of waste removal is soil decontamination. Its goal is to remove harmful substances and regain the original use of the soil.

Abstract:

This thesis focuses on the great threat of soil erosion. We live in a fast moving world where roads, motorways, and buildings are being built with no regard to soil protection. Soil erosion is faster and more visible. This thesis analyses and compares anti-erosion protection strategies of particular areas according to the land consolidation proposed by Land Registry, or according to a public erosion control calculator.

Abstract:

This diploma thesis inquires into the quality of the soils at 30 archaeological sites from the periods from Late Bronze Age to Early Bronze Age (1 250 - 450 BC). The aim of the thesis is to prove the dependence of the ratio of the cultivated cereals on the soil and other environmental factors in various regions. The secondary aim is the general observation of the changes, which could appear from this period until now. These changes are represented by the erosion, researched by various methods.

Abstract:

Dead plant biomass is a key pool of carbon in terrestrial ecosystems. Its decomposition in soil environments is thus an essential process of the carbon cycle. Fungi are considered to be the primary decomposers in soil ecosystems because of their physiological adaptations and enzymatic apparatus composed from highly effective oxidative and hydrolytic enzymes. Many recent works show that in addition to fungi, bacteria may also play a significant role in lignocellulose decomposition and among bacteria, the members of the phylum Actinobacteria are often regarded to significantly contribute to cell

Abstract:

The urban sprawl cannot be any longer perceived as a solely esthetic and socioeconomic problem. The process of shift of population and activities from city centre to its fringe has significant environmental impacts as well. Typicaly, suburban areas are spatially and therefore energetically demanding, the landscape is being fragmented by their presence and the natural environment of organisms is severely modified or destroyed. Soil sealing and impervious surfaces lead to altered heat and moist regimes, infiltration rate and runoff. Soils at city fringe - usually very productive and valuable - a

Abstract:

Permanent grass overgrowth holds a great importance in the Czech Republic's agriculture. It's functions in the landscape are mostly anti-erosive and landscape-creating. In comparison to other European countries, the ploughed area in the Czech Republic is larger. Therefore it is possible to expect an increase in the overall dimension of the ploughed area, which brings a necessity of land management. An insufficient level of used pratotechnical actions can cause a shift in the effects of grazing on the environment - from the positive to the negative. An excessive straining of herbage linked to t
