A New Approach to Humus Balancing in Organic Farming Organic Eprints
Brock, Christopher; Hoyer, Uta; Leithold, Günther; Hülsbergen, Kurt-Jürgen.
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.

ABOVEGROUND WOODY BIOMASS PRODUCTION OF DIFFERENT TREE SPECIES IN SILVOARABLE AGROFORESTRY SYTEMS WITH ORGANIC AND INTEGRATED CULTIVATION IN SOUTHERN GERMANY Organic Eprints
Huber, Julia; Siegel, Thomas; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
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...

Analyse des Energieeinsatzes und der Energieeffizienz bei der Futtererzeugung in der Milchviehhaltung Organic Eprints
Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
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.

Anecic, endogeic, epigeic or all three - acknowledging the compositional nature of earthworm ecological group data in biodiversity analysis Organic Eprints
Wolfrum, Sebastian; Siebrecht, Norman; Papaja-Hülsbergen, Susanne; Kainz, Maximilian; Hülsbergen, Kurt-Jürgen.
Agriculture and biodiversity are closely connected. Especially the soil ecosystem is crucial in this relation. Earthworms are seen as good indicators for the health and functioning of the soil. Beneath different biodiversity measurese earthworm ecological group data is analysed to assess soil biodiversity, fertility and capability to deliver ecosystem services. However this kind of data is compositional and needs a special statistical treatment. New available methods for this purpose were applied to data from the BIOBIO project (www.biobio-indicator.org) to gain better understanding of the complex relationship between earthworms, agricultural management and environment.

Anpassung bestehender Methoden zur Abschätzung der Bodenerosion an die Bedingungen des Ökologischen Landbaus Organic Eprints
Siebrecht, Norman; Kainz, Maximilian; Hülsbergen, Kurt-Jürgen.
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...

Auswirkungen der Einbindung einer Biogasanlage in ein ökologisches Betriebssystem Organic Eprints
Helbig, Susann; Grass, Rüdiger; Hülsbergen, Kurt-Jürgen.
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...

Biogas-Fruchtfolgeversuch Viehhausen - Versuchsanlage und Ertragseffekte auf Winterweizen Organic Eprints
Reents, Hans Jürgen; Kimmelmann, Stefan; Kainz, Max; Hülsbergen, Kurt-Jürgen.
In 2004/05, a field experiment regarding the effect of crop rotations for biogas-production to yield and soil properties was established at the organic experimental station Viehhausen. The different aspect of energy and food production and soil protection of the 5 main crop rotations are explained. The wheat yield 2007-09 was affected by legume percentage in crop rotation, which means partly lower yields but higher protein. The biogas slurry manuring increases the protein content in general but better in rotations with legumes.

Earthworm abundance and species richness: Contribution of farming system and habitat type Organic Eprints
Köhler, Anna-Sophie; Huber, Julia; Wolfrum, Sebastian; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
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...

Effekte von Energiepflanzen-Fruchtfolgen und Gärrestdüngung auf den Weizenertrag Organic Eprints
Levin, Karin; Schießl, Anja; Kimmelmann, Stefan; Reents, Hans Jürgen; Hülsbergen, Kurt-Jürgen.
Ein zweifaktorieller Feldversuch (Gärrestdüngung und Fruchtfolge) zur Untersuchung von Fruchtfolgen für die Biogasproduktion wird seit 2004/2005 in Viehhausen bei Freising durchgeführt. Die Düngung mit Biogasgärrest führte zu signifikant höheren Weizenerträgen gegenüber den ungedüngten Parzellen. Die höchsten Weizenerträge wurden in der Fruchtfolge mit dem höchsten Kleeanteil erreicht. Die Steigerung der Weizenerträge zeigt, dass Synergieeffekte zwischen Energie- und Nahrungsmittelproduktion möglich sind.

Einfluss der Bewirtschaftung auf Nodulation von Erle und Robinie in Agroforststreifen Organic Eprints
Chmelíková, Lucie; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
Root nodules arise because of symbioses between higher plants and N2-fixing soil bacteria. Legumes and Rhizobium as well as actinorhizal plants and Frankia are known for their symbioses. Nodules of black alder (Alnus glutinosa L.) and black locust (Robinia pseudoacacia L.) were investigated with soil monoliths (30 cm deep and 7 cm in diameter) from agroforestry strips (organic and integrated management). The farming system had significant influence on the nodule number of black alder, but no influence on nodule number of black locust. For further research and evaluation the other nodule traits, soil conditions and root biomass will be used.

Einfluss von Fruchtfolge, Stallmistdüngung und Senfzwischenfrucht auf das Brandsporenpotenzial von Steinbrand- (Tilletia caries) und Zwergsteinbrandsporen (T. controversa) im Boden Organic Eprints
Voit, Benno; Killermann, Berta; Bauermeister, Regula; Hülsbergen, Kurt-Jürgen.
Common and dwarf bunt of wheat are important diseases in ecological farming. High infection levels lead to an increase of the spore potential in soil. 3 and 4 years randomized crop rotation field trials are performed at 3 sites with 4 replicates on naturally infested fields with either T. controversa or T. caries spores with crop rotation links commonly used in organic farming to determine whether it is possible to decrease the spore potential in soil. The influence of stable manure on bunt spores is tested. Brassica species setting free thiocyanate and isothiocyanate compounds after mulching are cultivated to examine the possibility to reduce the spore potential in soil. Soil samples are taken yearly from each plot and common and dwarf bunt spore...

Energiebilanzen und Erträge ökologischer und konventioneller Anbausysteme: erste Analyseergebnisse eines Dauerfeldversuchs in Süddeutschland Organic Eprints
Bryzinski, Taras; Hülsbergen, Kurt-Jürgen.
An agrosystems trial in the south of Germany (near Munich) was established in 2009/2010 to quantify, analyze and model the effects of four organic and two non-organic agricultural systems on the yields, the soil and the environmental footprint. The differential und influential factors between the systems are: crop rotation, harvest index, plant protection and fertilization. The first results in the years 2011-2013 have shown significant differences in the crop yield (winter wheat) and the crop rotation yield (grain units) between organic and conventional systems and within this groups. The energy efficiency in plant production of organic systems with organic manure (digestate and slurry) are in the average of three years almost double as high as organic...

Energieeffizienz im ökologischen Landbau – am Beispiel der Wertschöpfungskette „Brot“ – Organic Eprints
Prem, Werner; Hechenbichler, Johannes; Lörcher, Michael; Manhart, Hugo; Hülsbergen, Kurt-Jürgen.
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.

Energy use efficiency of organic and agroforestry farming systems Organic Eprints
Lin, H. C.; Chmelíková, Lucie; Huber, Julia; Hülsbergen, Kurt-Jürgen.
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.

Greenhouse Gas Emissions of organic and conventional dairy farms in Germany Organic Eprints
Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
The article presents a model to calculate the greenhouse gas emissions of German dairy farms. The model was tested in 12 organic and 12 conventional farms in Southern and Western Germany. The results show that there is no significant difference between the greenhouse gas emissions per kg milk of the organic and the conventional farms. The lower milk yield of the organic farms is compensated by the lower fossil energy input and the higher carbon sequestration in the fodder production. It can also be seen that a raise of the milk yield from a medium level does not lead to a mitigation of greenhouse gas emissions per kg milk.
