The settlements situated on broad flat floodplains of rivers are threatened by floods during increased water flows in the rivers. The floodplain of the Dyje river situated in the area between the Nové Mlýny water reservoir and Břeclav has been protected from former annual floods since the 70s of the last century due to the water-management measures. The realised measures including the construction of the new floodway protect the town of Břeclav as well. A long-term research into the soil water regime of the floodplain forest is underway in the region. The results obtained document its historical evolution and current status. Only in the early April...

Impact of Arable Land to Grassland Conversion on the Vegetation-period Water Balance of a Small Agricultural Catchment (Němčický Stream)Original Paper

Soil & Water Res., 2010, 5(4):128-138 | DOI: 10.17221/7/2010-SWR  

This paper presents results of decadal (10-day) water balance simulations for the vegetation periods (April to October) of 2001 (normal year), 2002 (wet year) and 2003 (dry year) in the Němčický Stream experimental catchment (3.52 km2). The catchment is a typical agricultural area with a large extent of arable land. This paper shows that the model used (WBCM) is capable of reliably simulating decadal water balance components for the actual land use. The same model is then used to estimate water balance changes brought about when 10% of arable land has been transformed into permanent grassland. It is shown that this land use change results...

Evaluation of uniformity coefficients for sprinkler irrigation systems under different field conditions in Kurdistan Province (Northwest of Iran)Original Paper

In the past few decades, several coefficients of uniformity were developed to express the uniformity of water distribution for different sprinkler irrigation systems. Christiansen's uniformity coefficient seems to be the most popular uniformity coefficient used by researchers on the global scale. However, more coefficients have also been proposed by other researchers. Therefore, this study focused on evaluating different uniformity coefficients proposed and on investigating the effects of field conditions on the results obtained by means of those coefficients. In doing so, sprinkler uniformity tests were conducted by using rain-gauge in order to measure...

Changes of soil organic matter under minimum tillage in different soil-climatic conditionsOriginal Paper

Olga Svobodová, Jana Jančíková, Jan Horáček, Peter Liebhard, Věra Čechová

Soil & Water Res., 2010, 5(4):146-152 | DOI: 10.17221/1/2010-SWR  

Quantitative and qualitative soil organic matter properties were observed in a specific large area experiment (Chernozem - Gross Enzersdorf, Austria) and in a medium-term field experiment (Cambisol - Studena, Czech Republic). Two technologies - minimum tillage (MT) and conventional tillage (CT) - were compared by means of the determination of quantitative and qualitative soil organic matter parameters of the soil samples in the years 2004-2005. Cambisol showed higher values of quantitative soil organic matter parameters in MT compared to those in CT over the whole soil profile. For Cambisol, the qualitative parameters were almost comparable for both...

Field study of chlorotoluron transport and its prediction by the BPS mathematical modelOriginal Paper

Martin Kočárek, Radka Kodešová, Josef Kozák, Ondřej Drábek

Soil & Water Res., 2010, 5(4):153-160 | DOI: 10.17221/42/2010-SWR  

The chlorotoluron transport in the soil profiles was studied under field conditions on three different soil types of the Czech Republic. The herbicide was applied on 21. 4. 2005 on a four-square meter plot using an application rate of 2 kg/ha. Soil samples were taken on days 35 and 150 from the herbicide application to study the remaining chlorotoluron distributions in the soil profiles. The chlorotoluron distributions in the monitored soils were very similar 35 days after the herbicide application. The major part of chlorotoluron was detected in the top layer of the soil profile (0-8 cm). The highest concentration was obtained in the top 2 cm layer...

Do Andosols occur in the Czech Republic?Original Paper

Pavel Novák, Tomáš Khel, Jan Vopravil, Jitka Lagová

Soil & Water Res., 2010, 5(4):161-171 | DOI: 10.17221/24/2010-SWR  

The aim of this contribution was either to confirm or refuse the supposition that there are soils on the volcanic effusive rocks in the Bruntál district which can be assigned to the referential group of Andosols. The conditions for the genesis of Andosols are described and the diagnostic criteria of the andic process are defined both according to the principles of the WBR/FAO 2006 classification and according to the Slovak MKSPS 2000 classification system. In the Czech classification system, the diagnostics of Andosols has not yet been described or defined because their occurrence on the territory of the Czech Republic has not been confirmed till now....

Conversion of some soil types, subtypes, and varieties between the Taxonomic Classification System of Soils of the Czech Republic and the World Reference Base for Soil ResourcesOriginal Paper

Jitka Sládková

Soil & Water Res., 2010, 5(4):172-185 | DOI: 10.17221/10/2009-SWR  

The article illustrates the compatibility of the Czech Republic Taxonomic Soil Classification System validated in the CR with the international World Reference Base for Soil Resources. It utilises the archive data on the soil types, subtypes, and varieties from the General survey of agricultural soils in the Czech Republic and soil profiles from new soil survey on the pilot area of Litoměřice district. It indicates the possibilities of the future refinement of both systems.
