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 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... |

Fodder production requires the highest energy input in dairy farming. Taking the organic and conventional dairy farms from the project “climate effects of land use systems – evaluations on pilot farms” as an example we analyse the energy input for producing different fodder types and the influence of feeding strategies in Southern Germany. The results show that grazing is the most energy efficient form of feeding, followed by fresh grass and silage. Hay requires the highest energy input per unit forage energy. Maize silage has a lower energy input due to high yields. The higher the part of roughage in the ration the lower is the energy input for production of the ration. |

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... |

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... |

Bat activity in agroforestry systems at the research station Scheyern was analyzed using a N-mixture model approach. Results show low bat activity but provide hints that agroforestry structures can increase bat activity in open agricultural habitats. |

The aim of this study conducted at the experimental farm in Scheyern, was to investigate whether earthworm population in different habitats and under different farming systems (organic vs. integrated) differs. Arable land was compared with alley cropping systems, with meadows and field margins. For comparison purpose there were also investigations on the natural habitats fallow, forest and forest edge. The field study yielded the following results: In the meadow, the tree row in the alley cropping system and in the natural reference habitats (with exception of the studied forest), the abundance and species diversity was enhanced compared with arable land. In addition the tree rows in the alley cropping system had a positive effect on the earthworm... |

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. |

Im Versuchsbetrieb Scheyern (Süddeutschland) wurde in Feldexperimenten die Energienutzungseffizienz (EUE) ökologischer Anbausysteme analysiert. Die EUE wurde für verschiedene Systemebenen - die Fruchtarten, die Fruchtfolge sowie Agroforstsysteme (AFS) bestimmt. Die Agroforstsysteme bestehen aus Baumreihen mit schnellwachsenden Gehölzen zur energetischen Nutzung sowie einer Fruchtfolge zur Nahrungserzeugung. Die EUE entspricht dem Verhältnis von Energieoutput zum Energieinput. Der Energieinput umfasst den Einsatz fossiler Energie, der Energieoutput den Brennwert der Ernteprodukte. Die EUE von Weizen wird stark von der Vorfrucht beeinflusst; sie beträgt nach Kartoffeln 10,1, nach Luzerne-Kleegras 19,5, im AFS 9,7 (nach Kartoffeln) und 18,8 (nach... |

In der landwirtschaftlichen Beratung – auch bei Ökobetrieben – werden in der Regel produktionstechnische oder betriebswirtschaftliche Fragestellungen bearbeitet. Eine Beratung, die alle Nachhaltigkeitsdimensionen umfasst und dem Betriebsleiter ein Instrument an die Hand gibt, in dem der Gesamtbetrieb widergespiegelt wird, fehlt bislang. Ziel des noch laufenden Projektes ist die Entwicklung eines Beratungsangebots, mit dem landwirtschaftliche Betriebe wirksam bei einer nachhaltigen Entwicklung unterstützt werden können. Wichtiges Novum ist der Weg der freiwilligen, selbstbestimmten Betriebsentwicklung zu mehr Nachhaltigkeit in Abgrenzung zu von außen kommenden Richtlinien. |

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. |
