| Although it is the aim of organic farming to increase biodiversity, there is little knowledge about the impact of organic farming on birds. From 2001 to 2003, the number of breeding birds was recorded annually on the organic experimental farm of the Institute of Organic Farming (600 ha), and on adjacent conventional and organic farms (60 ha and 40 ha) in Northern Germany. The number of skylark (Alauda arvensis) territories increased considerably after the conversion from conventional to organic farming on the premises of the Institute. Their number remained unvaried on the conventional farm. The highest density of skylark territories was found on the farm which has been under organic management for many years. The number of yellowhammer (Emberiza... |

| Auf die in den 50er und 60er Jahren publizierten Theorien zur Bodenfruchtbarkeit von Hans Peter Rusch wird im organisch-biologischen Landbau heute noch Bezug genommen. Zu nennen sind hier der Rusch-Test zur Einstufung der biologischen Qualität der organischen Substanz und von Böden, die Systematisierung des Abbaus organischer Substanz im Boden und der Humusbildung sowie die Flächenkompostierung. Ruschs Lehren zielen auf eine Verbesserung der Bodengare durch effiziente Zufuhr organischer Substanz und Humusbildung sowie auf die Verbesserung der Ausnutzung von Nährstoffen. Gegen den Geist seiner Zeit grenzte sich Rusch von der Mineraldüngung ab und hebt die auch heute unbestrittene Rolle des Humus für die Bodenfruchtbarkeit hervor. Die tatsächliche Bedeutung... |

| Reduced tillage is often not applied in organic farming, because of expected increased weed pressure and, as a result, decreasing yields. On the other hand, the positive influence of reduced tillage on soils, for example on beneficial soil animals, is well known. Therefore, we investigated the influence of occasional reduced tillage (ORT) on yields of triticale and grass-clover and on earthworm biomass. Occasional reduced tillage means only setting aside the plough before drilling selected crops, which are known to perform well under the given local conditions. Already four weeks after drilling triticale, a positive effect on earthworm biomass could be revealed, which could be confirmed through the entire study. Yields of triticale and grass-clover did not... |

| In Northern Germany, a diverse and complex experimental farm of the Federal Agricultural Research Centre (FAL) was set-up in 2001 covering all main aspects of organic farming. Previously, the 600 ha farm had been managed conventionally. Adjacent conventional farms were used as reference. The aim of this project was to study collembolans, microbial biomass and soil organic carbon in six organically farmed fields managed as a crop rotation of six different crops compared with an adjacent conventionally managed field. We hypothesized that the specific management in organic farming promotes soil biota. Soil samples were taken during the growing season in 2004. Collembolan abundances and microbial biomass were lower under organic management, but, generally,... |

| Farming systems applying reduced tillage measures are expected to be beneficial for sustaining important soil functions (ecosystem services) and (soil)biodiversity. Furthermore a reduction in tillage intensity is connected to reduced need for energy and labour input. On the other hand waiving the plough is, especially in organic farming systems, suspected to lead to increased weed pressure and therefore decreases in yields. In this paper first results of a study on temporarily reduced tillage in organic crop-rotations are presented. Here the plough was set aside before drilling triticale at the end of four crop rotations, and expectable yields, earthworm biomass and weed pressure were investigated. First one-year-results, of the experiment on temporarily... |

| Collembolans, a widespread group of soil fauna, could potentially be used as indicators of management changes in (organic) farming systems. Therefore, we studied effects of reduced tillage compared with conventional tillage on collembolan communities in the short term. Results of a two-year field trial showed that collembolan communities are likely influenced by different tillage systems. However, these effects could not be statistically verified. Furthermore, annual variation seems to strongly influence the composition of collembolan communities. We tend to assign these effects to different crops cultivated during our study. |
