The influence of SO2 pollution on xylem differention in spruce was investigated. Besides sudi quantitative changes as reduced annual growth, qualitative dianges also occur. With pollution, the percentage of latewood increases. Tradieids are shorter, possess more pits and are more frequent per unit area.Eur. J. For. Path. 5 (:975) 152-161

In order to quantify the reduction potential for nitrous oxide (N2O) release from arable soils through the removal of crop residues, we conducted an experiment after sugar beet (Beta vulgaris L.) harvest with three treatments: (i) ploughing of the crop residues (+CR:D), (ii) returning residues after ploughing on the surface (+CR:S), and (iii) removal of the residues and ploughing (−CR). N2O fluxes were measured over 120 days in south Germany. High positive correlations between N2O fluxes and the CO2 fluxes and soil nitrate contents suggested denitrification as the main N2O source. N2O emissions in +CR:D was higher than in +CR:S (2.39 versus 0.93 kg N2O−N ha−1 120 d−1 in +CR:D and +CR:S). Residue removal in −CR reduced the N2O emission compared to +CR:D by 95% and to +CR:S by 87%. We further conducted a meta-analysis on the effect of crop residue removal on N2O emissions, where we included 176 datasets from arable soils with mainly rain fed crops. The overall effect of residue removal showed a N2O reduction of 11%. The highest N2O reduction of 76% was calculated for the removal subgroup with C/N-ratio < 25. Neither the remaining C/N-ratio subgroups nor the grouping variables “tillage” or “residue quantity” differed within their subgroup.

Abstract:The transition to the CAP and admission to the internal market triggered a shock wave in Austria which caused fundamental changes in the country's farming and food industries. Behavioural patterns stuck in traditional routines and petrified structures began to break up. The resulting thrust towards modernisation has been a major success of the EU integration. Eastern enlargement, about to be embarked on by the European Union, will have a greater impact on Austrian agriculture than the country's accession to the EU ever had. Farmers will have to brace for a loss of market shares and an additional pressure to adjust. The rural regions bordering the accession candidates will be particularly hit and thus require special attention in terms of economic policy measures. Agriculture and rural regions in Eastern Europe will profit from the EU-membership. Key words: agriculture, Common Agricultural Policy, EU-enlargement, AustriaAbstrakt: Pøechod ke Spoleèné zemìdìlské politice EU (dále jen SZP) a otevøení rakouského vnitøního trhu uvolnily ok vyvolaný pøizpùsobovacím procesem, který zásadnì zmìnil rakouské zemìdìlství a potravináøský prùmysl.
