Einfluss von Fruchtfolgen zur Biomasseproduktion und Gärreste-Düngung auf Bodenstruktur und mikrobielle Aktivität

Summary in the original language of the document

In a field experiment with five different main crop rotations and fives subtypes for organic biogas systems, aggregate stability, organic carbon, total nitrogen and catalase were evaluated in the topsoil layer in spring 2010, 2011 and 2013 in a winter wheat stand. Aggregate stability was enhanced by variation of crop rotation but not on manuring with biogas slurry. Rotations with a higher percentage of legumes led to a higher aggregate stability. On the other hand catalase activity was improved by biogas slurry.
