A high displacement of inhabitants into large towns, presence of industry, and constantly growing traffic have a high impact on the environment and considerable exposure of human health to environmental risks. Therefore, putting emphasis on the best environmental quality is necessary. In this work, the pollution level of urban parks was studied, the influence of the type of pollution source was analysed, and the effect of shading by trees was studied. The analyses were carried out on soil samples taken from thirteen parks in two towns of the Czech Republic, in Prague, a town considered to be mainly residential, and Ostrava, a predominantly industrial...

A two-year experiment was conducted in the desert west of the Nile Delta to study the effect of applying fertilizers and other agronomic chemicals through sprinkler irrigation water (a technique referred to as chemigation) on wheat grain yield. Experiment included three levels of irrigation inputs, namely: I1 = potential evapotranspiration rate (ETp), I2 = 0.8 ETp and I3 = 0.6 ETp, and included two application method of fertilizers and herbicide (chemication and traditional). Applying chemigation resulted in significant increase in grain yield, ranging between 9.9% and 50.0% with averages of 43.2%...

One peculiar feature of the inland valleys abundant in West Africa is their site-specific hydrology, underlain mainly by the prevailing landforms and topography. Development and management of these land resources under the increasingly popular sawah (a system of bunded, puddled and levelled rice field with facilities for irrigation and drainage) technology is a promising opportunity for enhancing rice (Oryza sativa L.) production in the region. Information on the variations in selected soil physical properties as influenced by the prevailing landforms may serve as a useful guide in site selection. This is of practical importance since...
Acidification of forest soils in the Hrubý Jeseník regionOriginal Paper

The Hrubý Jeseník Natural Forest Region (NFR) is a border mountain territory which belongs to the areas most heavily impacted by air pollution in the Czech Republic. This paper compares results for soil properties investigated in non-limed forest stands during the years 1994 to 2007. Differences between the 2007 and 2000/01 surveys concerning Al, Ca and Mg content and pH in particular soil horizons are depicted using kriged maps. This means of interpreting laboratory analysis results allowed us to highlight the most endangered NFR areas from an acidification standpoint. Evaluation of results for Al, Ca and Mg content, their available forms and pH values...

In this study, three mathematical models in the SIRMOD package including the hydrodynamic (HD), zero inertia (ZI), and kinematic wave (KW) models were tested using the data from several field experiments for both border and furrow irrigation systems. Five data sets for borders and seven data sets for furrows were used in this assessment. The results indicated that the performance of all models was satisfactory for the prediction of the advance and recession times. There was no difference in the prediction of the advance and recession times and infiltrated and runoff volumes between the hydrodynamic and zero-inertia approaches of the SIRMOD software....
Comparison of two sensors ECH2O EC-5 and SM200 for measuring soil water contentOriginal Paper

The goal of this study was calibration of the ECH20 soil moisture sensor EC-5 and the sensor SM200 for selected soils of the Czech Republic. Based on the soil maps of the Czech Republic and various climatic conditions, five humic horizons of different soil types were selected: Stagnic Chernozem Siltic, Haplic Chernozem, Chernozem Arenic, Haplic Luvisol, and Haplic Cambisol. Soil properties (pHKCl, pHH2O, exchangeable acidity, cation exchange capacity, hydrolytic acidity, basic cation saturation, sorption complex saturation, oxidable organic carbon content, CaCO3 content, salinity, sand, silt, and clay content,...
