Effekt von Biogas-Fruchtfolgen und Biogas-Gülle auf Boden-struktur und weitere Bodeneigenschaften

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 pH were evaluated in the topsoil layer (0-5 cm) in April 2010 in a winter wheat stand. Aggregate stability reacted on variation of crop rotation but not on manuring with biogas slurry. Rotations with a higher percentage of legumes led to a higher aggregate stability. Nitrogen reacted in a similar way while organic carbon and pH were more influence by soil inhomogeneity.
