Soil map at the scale 1:250 000 was set up by means of transformation of the published and later digitised soil map of theCzechRepublic. The legend to this map reflects a new classification system of Czech soils that can easily be correlated with the reference international classification system FAO-WRB. In the next step this map was converted into the SOTER system, which links the soil cover to the geomorphology. The modification of the original SOTER procedure consisted in the abandoning of the consequent hierarchy geomorphology - lithology - soil associations. Only in territories characterised by rather shallow transported slope deposits over compact...
The influence of tillage treatments on water infiltration into soil profile

Plant Soil Environ., 2003, 49(7):298-306 | DOI: 10.17221/4128-PSE
Water infiltration into the soil profile and runoff losses in arable lands are related to the condition of the top layer. The tillage treatment (included no-till) of the top layer plays a key role in changes of the hydro-physical properties, mainly saturated hydraulic conductivity (K) of the treated layer. This paper is focused on the influence of repeated tillage treatments in the same locality on K in a relatively homogeneous soil profile. The field experimental work was conducted in 1997 and repeated in 2000 after three years of repeated treatments in an experimental field of the Research Institute of Plant Production, Prague on...

Sixteen soil samples from agriculturally used soils flooded in August 2002 were taken because new information about the state of soil contamination was required. The area in the Vltava river basin from Pragueto Mělník and in the Laberiver basin from Neratovice to Děčín was investigated. The samples were taken in September 2002 and analysed for the contents of potentially risky elements and persistent organic pollutants, including persistent dibenzodioxins and dibenzofurans. The results were compared with the data from the project Labe 1992. The findings show a low soil load of potentially risky elements and a slight reduction of their...
Salinity and sodicity hazard in water flow processes in the soil
F. Burger, A. Čelková
Plant Soil Environ., 2003, 49(7):314-320 | DOI: 10.17221/4130-PSE
This paper presents the results of the distribution of salinity characteristics (electrical conductivity and sodium adsorption ratio) of groundwater, and based on the results, it reports the evaluation of the salinity and sodicity hazards in the fluctuation processes of shallow mineralised groundwater, or in the processes if such groundwater is used for irrigation. The issue was studied for the soil-water environment in the south-east of the Danube Lowlands for the period 1991 to 1994. The measured data and data taken from archives were processed in the form of graphical attachments (appendixes, supplements, graphical documentation) - maps, by means...
Effects of heavy metal concentrations on biological activity of soil micro-organisms

Plant Soil Environ., 2003, 49(7):321-326 | DOI: 10.17221/4131-PSE
The distribution of cadmium, lead and zinc in exchangeable, organic, and 2M HNO3-extractable fractions as well as the effect of heavy metal concentrations on soil microflora was investigated. Six sampling transects were chosen in theLitavkaRiveralluvium in 1999-2001. Concentrations of all metals increased with decreasing distance from the source of contamination. The concentrations of Cd and Zn in exchangeable fraction were higher than in organically bound fraction, a reverse trend was found in Pb speciation. All measured parameters of soil microbial activity were affected by heavy metal concentrations. The decrease in CFU was most significant in the...
Changes in the composition of cell wall proteins in barley roots during germination and growth in aluminium presence

Root growth inhibition and loss of cell viability in barley root cells were induced by Al during germination of barley caryopses on filter paper moistened with 2mM AlCl3. The inhibition of root growth as well as loss of cell viability started on the third day of germination. This time was also needed for induction of Al-induced changes in the composition of cell wall proteins. The accumulation of three salt-extractable polypeptides with relative molecular mass 14, 27, and 29 kDa started 72 h after the beginning of germination of barley caryopses on Al containing filter paper. However, the inhibition of developmentally regulated deposition of three...
Sensory evaluation and some acetate esters of bottle aged Chardonnay wines

A five-year study was conducted to study the correlations between chemical analyses and sensory properties of wine during bottle aging. Chardonnay grapes were harvested as a normal and late harvest. After separate vinification, bottles were put in an underground cellar at12°Cand 75% of humidity. Chemical and sensory analyses were carried out after bottling (0), after 12, 24 and 36 months of bottle aging. The results of chemical and sensory evaluation show a strong correlation between a young wine bouquet and decrease in the concentration of isoamyl and 2-phenethyl acetates, and between an increase in diethyl succinate and bottle bouquet.
