Zum Anbau von Sojabohnen auf einem leguminosenmüden Standort in einem Dauerfeldversuch

Summary

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.
