Última Wasserhaushaltsmessungen in ökologisch bewirtschafteten Leguminosenbeständen im Trockengebiet Ostösterreichs Organic Eprints Pietsch, G.; Friedel, J.K.; Rinnofner, T.; Strauss- Siebert, A.; Loiskandl, W.; Kikuta, S.; Freyer, B.. Durch die Kombination von Feldmessungen und Simulation werden Änderungen im Bodenwassergehalt erfasst und Wasserbilanzen errechnet. Es ist vorgesehen in vier Plots (Meßprofile) die Bodenwasserspannung und den Wasseranteil online zu erfassen. Diese Profile dienen zur Erfassung der zeitlichen Auflösung an einem Standort und werden auch für die Kalibrierung der Simulation herangezogen. Die Simulation bietet die Möglichkeit unterschiedliche Szenerien zu bearbeiten und Sensibilitätsanalysen durchzuführen. Die Kombination der Messung und der Simulation ist eine sehr kostengünstige und flexible Vorgangsweise zur umfassenden Beschreibung der Stoffumsetzungsprozesse im Boden unter verschiedenen Bedingungen Tipo: Conference paper, poster, etc. Palavras-chave: Cereals; Pulses and oilseeds Soil quality. Ano: 2005 URL: http://orgprints.org/6231/1/Pietsch_et_al_2005_Wasser_PBT.pdf Plant biomass nitrogen and effects on the risk of nitrate leaching of intercrops under organic farming in Eastern Austria Organic Eprints Farthofer, R.; Friedel, J. K.; Pietsch, G.; Rinnhofer, T.; Loiskandl, W.; Freyer, B.. Data on the potential of intercrops to reduce soil nitrate contents, on their N accumulation and biological nitrogen fixation (BNF) are lacking for organic farming in the dry, pannonic region of Eastern Austria. The effect of legumes, non-legumes, and legumes + non-legumes used as intercrops on inorganic soil nitrogen, crop yield and biomass N, and BNF were tested in comparison to bare fallow. Non-legumes and legumes + non-legumes were more efficient than legumes in reducing inorganic soil N contents in autumn and nitrate contents in soil solution from the subsoil in winter. This reduction in inorganic soil N did not last until March of the following year due to an N mineralisation from the mulch. The legume + non-legume mixture contained a larger amount...

Data on the potential of catch crops to reduce soil nitrate contents, on their N accumulation and biological nitrogen fixation (BNF) are lacking for organic farming in the dry, pannonic region of Eastern Austria. The effect of legume, non-legume, and legume + non-legume crops used as catch crops on inorganic soil nitrogen, crop biomass and crop N, and BNF were tested in comparison to bare fallow.
