| Dem ökologischen Landbau werden im Vergleich zu konventionellen Systemen häufig geringere Umweltbelastungen zugesprochen. Ein bedeutender Aspekt sind Wirkungen auf Böden und deren Eigenschaften: Untersuchungen belegen höhere Gehalte organischer Substanz, eine verbesserte Struktur und ein vielfältigeres Bodenleben. Auch Hinweise zu reduzierten Bodenabträgen bestehen. Analysen zum Ausmaß der Wirkungen und den Prozessen sind jedoch kaum verfügbar. Bei der Modellierung von Bodenabträgen und der Ableitung von Maßnahmen sind entsprechende Informationen unabdingbar. Auf Basis umfangreicher Recherche wurden im Projekt Ursachen-Wirkungs-Beziehungen zwischen ökologischer Bewirtschaftungsweise und Bodenerosion erarbeitet. Es zeigt sich, dass die Wirkungen nicht auf... |

| About 8.8 % (UBA 2010) of the total greenhouse gas (GHG) emissions in Austria are caused by agricultural practices. Besides the release of climate relevant gases, C-sequestration occurs depending on the natural conditions and farming system. The focus of the project was to describe the GHG-emissions and sinks of the most relevant farming types, both organic and conventional, within the main production areas in Austria. Results of an intensively cultivated region in the North-West are presented. Based on the input data, six model-farms were created with the programme REPRO, whereby forage production, cash crops and refinement systems were considered. All systems had a positive humus balance and sequestered carbon in the soil, especially forage... |

| For the Hofpfisterei, one of biggest eco-bakery in Germany, the communication of the sustainable production of their bread plays an important role. The Hofpfisterei wants to introduce an environmental management over the supply chain, in order to improve among other things the energy efficiency. The potential is determined by a test net of organic farms by means of life cycle assessment. The reduction of energy input on the farms is to be judged as small. On the other hand the potential is high for energy output. The results show, that alone by the use of the clover grass in the market fruit farms, the energy outputs can be increased clearly. The goal of an energy autarky over supply chain can be achieved by this. |

| Biogas plants gain increasing circulation in organic agriculture. Among systems engi-neering effects on matter cycles, soil, plants and environment particularly depend on the integration of the biogas plant into the farming system. Ecological effects should already be taken into consideration in the planning stage. Therefore appropriate tools are required. In this contribution ecological effects of changing an organic cash crop farming system into a biogas system are shown by using an established modelling approach. Starting from an existing cash crop farm a biogas-scenario was developed which includes e. g. structural adaptations of the cultivation system and crop rotation, the use of internal products and manuring. The biogas plant was conceived as a... |

| The increasing demand for bioenergy and the combination of agricultural production with conservation has made agroforestry to a sustainable land-management option. Aboveground woody biomass plays a decisive role considering the economic value of the agroforestry systems as well as the carbon storage. With the objective to study aboveground woody biomass production of agroforestry systems with different cultivation methods (organic/ integrated), short rotation plantations of different tree species were established 2009 and coppiced in 2012. The studied tree species were black alder (Alnus glutinosa), black locust (Robinia pseudoacacia), poplar “Max 3”, (Populus maximowiczii x Populus nigra) and willow “Inger” (Salix triandra x Salix viminalis). At the end... |

| Biogas digestate is a by-product of the biogas process and contains high amounts of nitrogen, which makes it a valuable organic fertiliser. In a field trial near Freising, different crop rotations for biogas production were established in 2004/05 and fertilised with digestate only or were not fertilised (controls). A wide range of methods for soil analysis was used between 2013 and 2015 to identify the methods capable of showing a biogas digestate effect on soil quality. We learned that aggregate stability, C and N contents, and the number of earthworms showed significant differences between fertilised and unfertilised plots, while pH, water infiltration, bulk density and pore size distribution were not able to show biogas effects. |

| Humus balances provide a profitable approach for humus dynamics assessment in farming practice. Nevertheless, there is a clear demand for methodological adaptation. This article presents a new approach to humus balancing using reproducible algorithms for the estimation of balance coefficients. Humus balance coefficients for crops and organic fertilizers are estimated according to a bipartite algorithm. Humus demand is calculated on the basis of crop yields referring to the nitrogen household in the plant-soil system. Humus supply is derived from organic matter input with plant material and fertilizers. The new approach facilitates the adaptation of the method to new situations. |

| The aim of this study was to evaluate the interaction between yield levels of nonleguminous crops and soil organic matter (SOM) under the specific conditions of organic and conventional farming, respectively, and to identify implications for SOM management in arable farming considering the farming system (organic vs. conventional). For that purpose, correlations between yield levels of nonlegume crops and actual SOM level (Corg, Nt, Chwe, Nhwe) as well as SOM-level development were examined including primary data from selected treatments of seven long-term field experiments in Germany and Switzerland. Yield levels of nonlegume crops were positively correlated with SOM levels, but the correlation was significant only under conditions of organic farming, and... |

| In 2009/10 a field experiment was established at the experimental station Viehhausen to analyze the effects of different farming systems to yield and soil properties. Two of these are organic cash crop systems. A biogas plant is integrated in one of these – called biogas system. The analysis regarding to the economic effects of the biogas plant from the years 2010-2013 show an improvement of the economic results for the biogas system. The reasons are higher cash crop yields because of the manuring with digestate and the profit of the biogas plant. |

| La fertilità del suolo è riconosciuta come valore fondante sin dai pionieri dell'agricoltura biologica ma, ancor oggi, alla conservazione di un suolo fertile non viene attribuita abbastanza attenzione. Eppure l'agricoltura biologica dipende da una buona e naturale fertilità del suolo. |

| Steinbrand und Zwergsteinbrand sind bedeutende Krankheiten im ökologischen Landbau. Starker Befall führt zu einem Anstieg des Brandsporenpotenzials im Boden. 3-jährige, randomisierte Fruchtfolgeversuche werden an drei Standorten in vier Wiederholungen auf frisch befallenen Flächen durchgeführt. Die Böden weisen dabei entweder Brandsporen von T. controversa oder von T. caries auf. Es soll im Rahmen des Versuchs überprüft werden, ob durch im ökologischen Landbau übliche Fruchtfolgen das Brandsporenpotenzial im Boden reduziert werden kann. Durch Anbau von Senf als Zwischenfrucht wird getestet, ob durch die Freisetzung von Thiocyanaten und Isothiocyanaten nach dem Mulchen und anschlieβendes Einarbeiten in den Boden eine Abnahme der Sporenzahl im Boden erfolgt.... |

| Zvyšování půdní úrodnosti bylo pro průkopníky ekologického zemědělství základem veškerého jejich úsilí. Přesto zachování úrodné půdy mnohdy nebyla věnována dostatečná pozornost. Ekologické zemědělství je však na přirozené půdní úrodnosti závislé. Oslabená a poškozená půda nám nemůže poskytnout to, co od ní očekáváme. Udržet úrodnost půdy vyžaduje velkou péči. Předkládaná brožura ukazuje půdní úrodnost z různých úhlů pohledu. Naším záměrem však nebylo vytvořit obecně platný „návod k použití“. Informace mají být mnohem spíše podnětem k tomu, aby se o vztahu člověka k půdě smýšlelo jinak a aby se tento vztah utvářel ve prospěch budoucnosti. |
