Metal stabilisation effects of amendments (1% m/m CaCO3-L, 5% m/m municipal sewage sludge compost-MSSC, and 7.5% m/m natural zeolite-Z) were studied on acidic mine spoil (pHKCl 3.73) from Gyöngyösoroszi (Hungary) containing Cd-15.0, Cu-336, Mn-568, Pb-1919, and Zn-3306 mg/kg. Red fescue (Festuca rubra, cv. Keszthelyi 2) was grown in a pot experiment in amended mine spoil, and was infected with spores of a Zn-tolerant arbuscular mycorrhizal fungi (AMF) Glomus intraradices. During 12 weeks of plant growth L + MSSC + Z amendments were more effective in stabilizing the pH, reducing the leaching and phytoavailability...

The aim of the study was to monitor the incidence and to detect the presence of viruses of yellow dwarfness in barley (BYDV-PAV, BYDV-RMV), of yellow dwarfness in cereals (CYDV-RPV) and dwarfness in wheat (WDV) in stands of winter wheat and winter barley in Slovakia. During the period 2001-2004 a total of 292 samples coming from 150 localities were analyzed. This involved 190 samples of winter wheat (39 varieties and 13 breeding lines) and 102 samples of winter barley (17 varieties and 7 breeding lines). The detection of viruses was carried out with the aid of the method DAS and TAS ELISA. During the years surveyed, the occurrence of the various viruses...

Field experiment demonstrated the benefit resulting from biological soil management including the use of N2-fixing and growth promoting bacteria A. brasilense B-4485 for long-fibred flax. Seed inoculation by A. brasilense B-4485 was equivalent to the introduction of 15 kg/ha of N that provided the possibility of partial flax N requirement supply. Treatment A. brasilense + N15P60K90 is considered to be the most profitable management in regard to flax yield and its quality, and is comparable to N30P60K90 treatment. Biological management allows preventing...

In precise field trials in the CR in the years 2004 and 2005 the effect of site conditions, yellow- and purple-fleshed varieties and fertilization on the content of total polyphenols (TP) in potato tubers was investigated. Comparing four localities, significantly highest TP content (by 5.7 to 13.4% higher than in other localities) was determined in the locality Stachy in both years, which we ascribe to apparently lower temperatures in the vegetation period in this locality of high altitude. In comparison to yellow flesh varieties, in the case of purple flesh Valfi variety TP content higher by 52 to 153% was recorded as the average of both years. As...

Plant Soil Environ., 2006, 52(9):413-423 | DOI: 10.17221/3460-PSE  

The uptake of As, Cd, Pb, and Zn and potential phytoremediation efficiency of five high biomass producing crops, white sweetclover (Melilotus alba L.), red clover (Trifolium pratense L.), curled mallow (Malva verticillata L.), safflower (Carthamus tinctorius L.) and hemp (Cannabis sativa L.) commonly used as grazing and/or energy crops was evaluated in both pot and field experiments at soils with different level of element contamination. In pot experiment the highest phytoremediation efficiency was demonstrated by C. tinctorius where 4.8% of Cd and 1.1% of Zn were removed...

Soil depth prediction supported by primary terrain attributes: a comparison of methods

V. Penížek, L. Borůvka

Plant Soil Environ., 2006, 52(9):424-430 | DOI: 10.17221/3461-PSE  

The objective of this study was to investigate the benefits of methods that incorporate terrain attributes as covariates into the prediction of soil depth. Three primary terrain attributes - elevation, slope and aspect - were tested to improve the depth prediction from conventional soil survey dataset. Different methods were compared: 1) ordinary kriging (OK), 2) co-kriging (COK), 3) regression-kriging (REK), and 4) linear regression (RE). The evaluation of predicted results was based on comparison with real validation data. With respect to means, OK and COK provided the best prediction (both 110 cm), RE and REK gave the worst results, their means...

BURIS/EBS - Electronic exchange trade with agrarian commodities in the Czech Republic - Information

Plant Soil Environ., 2006, 52(9):431-434 | DOI: 10.17221/3462-PSE  

The Czech University of Agriculture in Prague in cooperation with the Business Exchange in Hradec Králové operates an electronic business system EBS, which enables on-line exchange trade negotiations through the Internet. The system fully takes the advantage of possibilities and technologies of e-business, bringing thus forward new opportunities for making use of the exchange trade with agricultural and food commodities on the EU liberal market. The whole procedure is a part of the Agrarian www portal AGRIS.
