| Gerade im viehlosen ökologischen Landbau ist die Fruchtfolge eine der wichtigsten Einflussgrößen, die den pflanzenbaulichen Erfolg bestimmen. Als Stickstoffquelle stehen neben Kleegras auch vermarktungsfähige Leguminosen wie Soja zur Verfügung. Zwei der Fruchtfolgen des Dauerfruchtfolgeversuchs an zwei Standorten der Landesanstalt für Landwirtschaft lassen einen Vergleich zwischen Soja und einjährigem Kleegras in ihrer Wirkung auf die Nachfrüchte Winterweizen und Sommergerste zu. Die Erträge und auch die Qualitäten sind nach Soja signifikant niedriger als nach Kleegras, was die geringere Vorfruchtwirkung von Soja bestätigt. Betrachtet man dagegen die durchschnittlichen Fruchtfolgeerträge in Getreideeinheiten pro Jahr, liegen diese in beiden Fruchtfolgen... |

| A high turnover of Humus is one of the goals in organic farming. The effect of different crop rotations on the content and the quality of humus was examined in two long term field experiments in Bavaria, South Germany. The three and five years crop rotations differed in the utilization of grass clover swards (cutting or mulching), in the following crops (potatoes or barley) in the portion of grass clover swards (33 and 40 %) and in the legume art (grass clover or grain legume). The soil samples were taken in 1998 (beginning of the trials), in 2010 and in 2013 and were analyzed for Corg and Nt. The development of the Corg- and Nt-contents was better in the crop rotations with grass clover swards (increasing) than in the crop rotation with grain legume... |

| 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. |
