| In a field experiment at the Experimental Farm for Organic Farming in Northern Germany, the effect of sulphur application in the form of MgSO4 to a red clover-grass mixture was measured in the year 2011. At the beginning of the vegetation period in the spring plots were fertilised with 30 and 60 kg S ha-1. The sulphur fertilisation resulted in significantly higher fresh weight and dry matter yields and otherwise in a lower dry matter content as compared to an unfertilised treatment. The content of crude protein and sulphur were significantly increased by sulphur application. The N/S-ratios in the fertilised plots showed values below the threshold of 15 for an adequate supply of sulphur. The N-withdrawals added up over the three cuts increased in the... |

| Auf dem landwirtschaftlichen Betrieb Rutzendorf soll ein umfassendes Langzeitmonitoring zur Entwicklung des biologischen Landbaus eingerichtet werden. Ein wissenschaftliches Konzepts soll erarbeitet und zum Teil schon umgesetzt werden. Die Wirkungen der Umstellung auf Ökologischen Landbau auf Boden, Wasser, Flora und Fauna soll anhand ausgewählter Eigenschaften erfasst werden. Entsprechend der Konzeption des Betriebs (vgl. ¿Konzept Biobetrieb Rutzendorf¿, Bericht an das BMLFUW, IfÖL, BOKU, März 2002) sollen drei Düngungsvarianten verglichen werden. Die Bedeutung verschiedener vorhandener Biotope (Gehölzstreifen, Hecken, ...) soll charakterisiert und neue, ergänzende Biotope geplant und angelegt werden. Versuchsort und -gegenstand ist der... |

| Bisher war es für Kompost und Gärgut in Ökobilanzen üblich, die Nährstoffe als Substitute von Mineraldüngern und die Schwermetalle als Belastungen einzusetzen. Im Vergleich zur Verbrennung, wo die organische Substanz vollständig mineralisiert und energetisch genutzt wird, gibt es bei Kompost und Gärgut eine Lücke: wie soll die organische Substanz bewertet werden? Zur Bewertung der organischen Substanz in Ökobilanzen gibt es zwei grundlegend verschiedene Vorgehensweisen: 1. Einsetzen der einzelnen Effekte wie Erosionsreduktion, weniger Zugkraftbedarf, bessere Wasserhaltekapazität, weniger Krankheitsanfälligkeit etc. mit jeweils entsprechenden LCA-Modulen 2. Globales Einsetzen von Substituten, welche die Effekte möglichst gut abbilden. Gegen die erste... |

| Using biomass from intercrops as feedstock for biogas production makes it possible to produce renewable energy without compromising food production. In order that using intercrops for biogas and fertilizing with liquid digestate is sustainable, it must be secured that this practice does not have adverse effects on soil fertility. Two-year randomised field experiments were conducted on two different soil types near Bruck/Leitha (A). On chernozem soil, soil pH and composition of the cation exchange complex were hardly influenced by liquid digestate. Also on a parachernozem with pH 5.9 short-term effects of liquid digestate were small due to the low salt content and high C/N ratio of the digestate. Nevertheless the distinct increase in soil K content shows... |

| Hairy vetch (Vicia villosa) is playing an important role to improve soil physical properties and soil fertility for the supply of crop nutrients and this crop is also used as a representative legumes green manure for the production of organic agricultural food. In this study we evaluated the availability of hairy vetch in reclaimed organic rice cultivation. The response to increasing salinity was analyzed by means of the germination rate and seedling growth of hairy vetch. Results showed that seed germination of hairy vetch decreased insignificantly up to concentration of 0.6% NaCl. However, shoot and root growth of hairy vetch showed significant reduction at salinity concentrations higher than 0.1% NaCl level. In these results we were considered that... |

| O objetivo deste trabalho foi avaliar o desempenho de seis cultivares de soja, sob manejo orgânico, para fins de adubação verde e produção de grãos. Utilizou-se delineamento experimental de blocos casualizados, com quatro repetições por tratamento (cultivar). Na época da colheita, 81 dias após a emergência das plântulas, todas as cultivares testadas (Celeste, Surubi, Campo Grande, Mandi, Lambari e Taquari) mostraram excelente nodulação, variando de 545 a 760 mg/planta de massa nodular seca. As cultivares Celeste e Taquari, que produziram, respectivamente, 8,33 e 7,12 t ha-1 de biomassa seca da parte aérea, apresentaram outras características agronômicas vantajosas, tais como: ciclo curto, alta acumulação de nutrientes (N, P, K, Ca e Mg) nos tecidos verdes... |

| De bemesting met stikstof en fosfaat wordt in de Nederlandse landbouw begrensd. Dit heeft ook consequenties voor de biologische teelt. Om inzicht in deze consequenties te krijgen zijn bouwplan en bemesting op twee akkerbouwbedrijven en drie tuinbouwbedrijven geanalyseerd, zijn meerdere deskundigen geraadpleegd en is de relevante literatuur bestudeerd. |

| Este trabalho foi realizado através de uma revisão bibliográfica a respeito da adubação verde e os benefícios proporcionados com a adoção dessa prática, com o objetivo de divulgar os principais resultados científicos nessa área. Verificou-se que a adubação verde proporciona melhorias significativas nas características químicas, físicas e biológicas do solo. As características químicas são beneficiadas pela liberação de nutrientes com a decomposição dos resíduos. Essa prática melhora as características físicas favorecendo a agregação do solo, maior retenção de água e prevenindo a erosão. A biomassa dos adubos verdes melhora as características biológicas do solo constituindo em alimento para esses microrganismos. Espécies utilizadas como adubos verdes são... |
