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 of metals in mine spoil than the lime application itself. Liming (L) had a negative effect on Cd, Mn and Zn concentrations in mine spoil water (leachate) as compared to the untreated control. In mine spoil stabilized with a combination of amendments red fescue growth can be established in symbiosis with AMF. Rate of AMF infection (F 4%) was low in limed mine spoil but was especially high (F 93%) in the case of L + MSSC + Z application. In shoots of these cultures - as a trend - AMF reduced the concentration of Cd by 35-55%, Cu by 9-34%, Mn by 14-55%, and Zn by 22-44%.

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 differed. In 2001, the most represented virus proved to be the WDV (68%); in 2002, it was the strain PAV of the virus BYDV (93%); in 2003, the most numerous were the virus WDV (71%) and the strain PAV of virus BYDV (67%). Similarly, in 2004, two viruses were represented about evenly, WDV and BYDV-PAV (75%). The more frequent of the two species was the virus BYDV, with the strain BYDV-PAV predominating. The intensity of viral infection of stand cereals differed during the experimental years, being highest in 2002 when the blight occurred both locally and also on a large-scale. The highest frequency of the disease was in Western and Eastern Slovakia.

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 high concentrations of N in soil, excludes lodging and negative effects on flax yield and its quality. Implementation of biological management for flax nutrition may be profitable for both ecology and economy of long-fibered flax growing.

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 for the group of eight yellow flesh varieties, Karin variety had the highest TP content and showed a significant increase in comparison to Agria, Saturna and Asterix varieties by 67, 60 and 37%, respectively. TP content was not demonstrably affected by fertilization with mineral fertilizers, but we recorded a tendency to lesser TP content (by 3 to 9.9%) in the variant with higher potassium and magnesium fertilization (166 kg K/ha and 60 kg Mg/ha).

In pot experiment the highest phytoremediation efficiency was demonstrated by C. tinctorius where 4.8% of Cd and 1.1% of Zn were removed from the moderately contaminated soil in one vegetation period when repeated harvest of aboveground biomass was performed. The removal of As and Pb was negligible for all the investigated plant species. At the highest element content in soil inhibition of plant growth due to the element phytotoxicity to plants was reported in most of cases. In the precise field experiment lower phytoremediation efficiency (biennial phytoremediation factors did not exceed 0.2% for Pb and Zn and 0.3% for Cd for C. tinctorius) was determined but yield suppress was not observed. Thus, free space for manipulation with element mobility in soil to increase element uptake by plants remains for further research.

Borůvka Author-Workplace-Name: Czech University of Agriculture in Prague, Czech Republic Title: Soil depth prediction supported by primary terrain attributes: a comparison of methods Abstract: 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 were significantly lower (79 and 108 cm, respectively) than the mean of real data (111 cm). F-test showed that COK with slope as covariate gave the best result with respect to variances. COK also reproduced best the range of values. The use of auxiliary terrain data improved the prediction of soil depth. However, the improvement was relatively small due to the low correlation of the primary variable with used terrain attributes.
