| One of the aims of organic farming is the protection of biodiversity. In the EU FP7 project BioBio, we studied the effect of organic farming on species numbers at farm level on 169 randomly selected organic and non-organic farms with mostly low to medium intensity in ten European regions. Using a preferential sampling scheme based on habitat mapping, numbers of plants, earthworms, spiders and bees were assessed at farm level. A global analysis across the ten regions shows that organic farms have significantly higher numbers of plant and bee species than non-organic farms. The effect of organic farming on earthworm and spider species numbers are also positive but insignificant. The effects in absolute terms are small and much smaller than the variation... |

| Problemstellung/Ziele: Die Erbse gilt als die wichtigste Körnerleguminose im Ökologischen Landbau, sowohl in ihrer Funktion als Leguminose zur Versorgung des Betriebes mit Stickstoff, als auch für die Futterproduktion (Geflügel und Schweine). Unter der Annahme einer richtigen Stellung in der Fruchtfolge gelten der Ertrag, die Stickstoff-Fixierungsleistung sowie die Konkurrenzkraft gegenüber Beikraut als die wichtigsten Merkmale in der Entscheidungsfindung der Sortenauswahl. Für die Tierernährung ist die Proteinqualität, im engeren Sinn der Gehalt an essentiellen Aminosäuren entscheidend. Ziel dieses Projektes ist die Untersuchung verschiedener Erbsensorten bzw. -gemenge im Hinblick auf ihre Biomassebildung, Stickstoff Fixierleistung, Konkurrenzkraft... |

| Körnerleguminosen enthalten in ihren Samen einen hohen Proteingehalt und können so ausgezeichnet zu einer ressourcenschonenden, eiweißreichen und gesunden Ernährungsweise beitragen. Im vorliegenden Versuch wurden sechs Speise-Körnerleguminosen in einem Feldversuch am Versuchsstandort Lambach /Stadl-Paura auf ihre Anbaueignung im oberösterreichischen Alpenvorland getestet. Deckungsbeiträge wurden errechnet. Bei einem Preis von 1,90 € kg-1 sind sehr hohe Deckungsbeiträge – bis zu 2300 € ha-1 für die Trockenbohne „Black Turtle“ – möglich. Der Versuch zeigte, dass es im humiden Alpenvorland möglich ist, Körnerleguminosen für Speisezwecke anzubauen, und dass sich ihr Anbau für LandwirtInnen als interessante Option erweisen kann. |

| The main source of nitrogen in organic farming is biological nitrogen fixation, the result of a symbiosis between legumes and nodulating bacteria. Lucerne (Medicago sativa L.) is the most biomass efficient forage legume under the semiarid conditions in East-ern Austria. Farmers inquired about information on the best site-adapted lucerne variety, but knowledge about water use and productivity of different lucerne varieties in organic farming is sparse. From 2005-2006, four lucerne varieties were studied with respect to above- and below-ground biomass production, biological nitrogen fixation and water use. The aim of this study was to find first practical criteria for farmers to choose lucerne varieties for green manure use, adapted to the dry region in the... |

| On organic farms, phosphorus (P) balances are often negative because no or little P is imported into the farms. Negative P balances may deteriorate P availability over time. We calculated P balances of the main farm production types in organic farming for the main Austrian production areas. Using data from various data bases and expert knowledge, we applied the sustainability assessment tool REPRO for calculations. The P balances were balanced to slightly deficient for organic forage dairy farms, cash crop farms and permanent crop farms, and slightly to highly surplus on organic refinement, pig producing farms. Deficient P balances, mainly on organic cash crop farms, call for P input especially on farms where available P fractions in the soil are very low... |

| Die Klimawandel-bedingte Zunahme von Trockenperioden in Gegenden mit geringen Niederschlägen erfordert Anpassungsstrategien im ökologischen Ackerbau. Außer trockenheitstoleranten Sorten wurden in einem Langzeitversuch auf einem viehlosen Ackerbaubetrieb in der semi-humiden Region im Osten Österreichs vier hauptsächliche Strategien gemeinsam angewandt: eine Futterleguminosen-basierte Fruchtfolge mit Zwischenfruchtgemengen, organische Düngung mit Luzernemulch, Biokompost oder Stallmist, reduzierte, nicht-wendende Bodenbearbeitung und Gehölzstrukturen. Mit diesen kombinierten Strategien waren die Humusgehalte stabil bis ansteigend, die Wasserinfiltration und pilzliche Biomasse im Oberboden wurden gefördert, die Erträge der Marktfrüchte waren... |

| In order to assess the risk of the use of recycled phosphorus (P) fertilisers for organic farming, the potential accumulation of heavy metals in soil after a 200-year fertilizer application equivalent to 11 kg P ha-1 yr-1 was calculated in a mass balance approach. Both fertilizers currently allowed in organic farming and recycled P fertilizers were regarded. For heavy metals, four scenarios with two soil pH levels (pH 5 and pH 7) and two precipitation excess levels (F 0.1 and F 0.3 m yr-1) were calculated. Recycled P fertilizers like struvite, meat- and bone meal, ashes, sewage sludge and digestate, as well as phosphate rock and triple superphosphate had a higher P content and a lower heavy metal-to-P ratio than composts. Consequently, compost application... |

| Biogas production is a key technology for sustainable use of biomass from agricultural production. An optimisation of biogas production from energy crops should not confine to the consideration of the biogas process. To assure a durable success, cropping of energy plants has to be designed according to the principles of sustainable crop rota-tions. Only in site-adapted and ecologically balanced crop rotation systems, energy crop production is meaningful. The general aim of this study was to develope site-adapted crop rotation systems including energy crops as main and catch crops. Study regions were chosen to represent large regions of Austria. To include a great share of the crop species relevant for Austria, sites from the dry region (NUTS III region... |

| An efficient phosphorus (P) recycling from urban areas is becoming an increasing issue due to the scarcity of natural P deposits. In order to assess the environmental performance of different approaches of P recycling, a LCA assessment and risk assessment studies were carried out. Generally, we found the supply of recycled P-fertilisers (RPFs) to be competitive as compared to conventional sources in terms of LCA results analysed in this contribution: per kg P and with exclusion of infrastructure processes, the highest abiotic depletion potential is shown for conventional mineral fertilisers based on phosphate rocks due to the finite mineral P resources. For fossil primary energy demand, the recycled fertilisers (struvites and an ash-based fertiliser... |

| The pollutant input and the risk of contamination by long-term application of recycled P fertilizers (RPFs) in European agricultural soils were estimated by a mass balance approach. Calculations based on literature data were carried out for the potentially toxic elements (PTEs) Cd, Cr, Cu, Ni, Pb, Zn and for the persistent organic pollutants (POPs) PCBs, PAHs and polychlorinated dibenzo-dioxins and -furans. The PTE accumulation estimation during 200 years of fertilizer application, equivalent to 11 kg P ha-1 year-1, the mean P export via harvested products on European stockless organic farms, regarded soil background concentrations and proposed threshold concentrations. For PTEs, inputs were fertilizer application, atmospheric deposition and liming, output... |

| Genetic variability is the fundament of life. Large genetic variability within species is the basis for adaptation to changing environmental conditions. Farmers and breeders have developed a multitude of crop cultivars and animal breeds to stabilize and increase quality and productivity. This study evaluated genetic diversity within different organic and non-organic farming systems using crop-cultivar and livestock-breed information as simple indicators. Data was collected using on-farm surveys in 15 case study regions in Europe and beyond. Selected indicators revealed strong differences of cultivar diversity between different countries and farming systems across Europe. No or only small differences were detectable between organic and non-organic farming... |

| Organic and low-input farming systems provide habitats for wildlife on farmland. The EU FP7 project BIOBIO has identified a core set of 23 indicators relating to the diversity of habitats, of species, of crops and of livestock. Management indicators capturing the pressure on biodiversity are also proposed. The indicators were identified in an iterative process between scientists and stake-holders to make sure that they are not only scientifically sound but also practicable and attractive. They were tested in 12 case study regions on four major farm types. Allocating 0.25 % of the CAP budget to a farm scale biodiversity monitoring would allow to measure and analyse the indicators on 50,000 farms across Europe. |

| Die vorliegende Arbeit untersucht die schwierige Herausforderung, Kleegras in Systemen reduzierter Bodenbearbeitung vollständig umzubrechen. In einem Feldversuch in Bayern wurde eine Eigenbau-Zinkenwalze, die gegen die Fahrtrichtung rotiert, als Nachläufer eines Kreiselgrubbers mit Stabwalze getestet. Die Erwartung war eine verstärkte Austrocknung der Kleegras-Stoppeln bei Einsatz der Zinkenwalze. Die Versuche wurden auf drei Schlägen durchgeführt, die sich in Bodenart und Humusgehalt unterschieden (lehmiger Sand, sandig-schluffiger Lehm, anmooriger-toniger Lehm), mit Kleegras unterschiedlichen Alters. Die Trockenmasse sowie die Anzahl der Pflanzen der wiederaufwachsenden Biomasse waren bei der Kombination von rotierender Zinkenwalze mit Kreiselgrubber und... |

| Die Anbaueignung sechs verschiedener traditioneller Speisekörnerleguminosen (Alblinse, Berglinse, Rotholzer Trockenbohne, Black Turtle Buschbohne, Palerbse und blaue Lupine) im Alpenvorland wurde in diesem Versuch getestet. Die Versuchsfragen waren Anbaueignung, Unterschiede im Saatsystem (Breitsaat und Reihensaat) sowie Deckungsbeiträge. Unter allen Speisekörnerleguminosen erzielten die Bohnen die höchsten Erträge (1028 und 1628 kg/ha), gefolgt von der Palerbse (766 kg/ha) und den Linsen (457 und 537 kg/ha). Zwischen den beiden Saatsystemen zeigten sich keine signifikanten Unterschiede. |

| One year after the conventional farm started the conversion process in 2002, a long term farming system monitoring was established in the Eastern region of Austria. The goal was to evaluate the performance of organic arable farming and its biotopes (flowering stripes, hedges and tree rows), and specifically their impact on biodiversity. After nine years organic farming we note a considerable increase of biodiversity in the arable fields and accompanying biotopes. Indicators applied were soil fauna, breeding birds as well as weeds. Space-time aspects, rotation and management measures as well as crop specific characteristics were influencing the development of species diversity. The development of diversity however is limited due to the intense farming in... |
