| 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... |

| In stockless organic farming, crop rotation is one of the most important factors that determine the success of crop cultivation. Six crop rotation schemes in a long-term experiment of the Bavarian State Research Center of Agriculture at Viehhausen allow the estimation of the effect of crop rotations on grain yield and baking quality of winter wheat. 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 and in the type of legume (grass clover or grain legume).The lowest grain yield as well as the most inferior baking quality was shown after grain legume. The highest yield was obtained after the two-year grass-clover... |

| There is little experience in repeated growing of soybeans in a short term crop rotation in Germany. Also, the impact of soils with legume fatigue on soy beans is unknown. To gather information on potential problems with a high share of soybeans in organic cropping system under Bavarian soil and climate conditions, soybeans were grown each three years over three rotations in a long term field experiment on a legume fatigue soil. The yield and the crude protein content were raised or unchanged in the second and third cropping of soybeans. No pests were detected. Hence, a rotation break of two years seem to be in the medium term sufficient and there seem to be no interaction between soilborne diseases for pea and field bean. |
