Abschaetzung der Einwirkungen gentechnisch veraenderter Kulturpflanzen auf den Boden, vor allem auf die organische Bodensubstanz als Traeger der Lebensraumfunktion: Darstellung des Kenntnisstandes und Abschaetzung von Wirkungsszenarien

This study is intended to help in the assessment of possible impacts of transgenic crops and it's litter on soil. Special attention is drawn to the organic matter in soil. Especially chemical and biological aspects are briefly reviewed. Possible ways of influence of transgenic crops on the organic matter of soil as key issue for the function of soil as habitat for living organisms are discussed. It is attempted to define standards for the assessment of this kind of influences. Possible effects and interactions are assessed using different scenarios of impacts on soil. Areas of deficit in current knowledge and fields for future research are shown.
