Última Integration von Umweltzielen in die Betriebsoptimierung im ökologischen Landbau – Möglichkeiten und Grenzen am Beispiel des Versuchsbetriebes Klostergut Scheyern Organic Eprints Meyer-Aurich, Andreas; Schuler, Johannes; Zander, Peter; Bachinger, Johann. Am Beispiel der Reduzierung von Bodenerosion konnte modellhaft gezeigt werden, dass die Integration von Umweltzielen für einen integrierten Betrieb mit geringeren Opportunitätskosten verbunden ist, als dies bei dem ökologisch wirtschaftenden Betrieb der Fall ist. Aufgrund der Notwendigkeit einer vielfältigen Fruchtfolge mit Zwischenfrüchten bzw. Untersaaten im ökologischen Landbau, ist das Erosionsrisiko im ökologisch wirtschaftenden Betrieb bereits ohne Auflagen deutlich niedriger, als die im integrierten Betrieb. Ein integrierter Betrieb ist in der Regel nur durch Zahlung von Prämien zu einer Berücksichtigung von Umweltzielen bereit. Diese Anreize werden dem ökologischen Landbau bereits durch die höheren Produktpreise sowie die Grundförderung gesetzt....

Ano: 2003 URL: http://orgprints.org/1467/1/meyer%2Daurich%2Da%2D2003%2Dumweltziele%2Dbetriebsoptimierung.pdf Carbon footprints of crops from organic and conventional arable crop rotations – using a life cycle assessment approach Organic Eprints Knudsen, Marie Trydeman; Meyer-Aurich, Andreas; Olesen, Jørgen E.; Chirinda, N.; Hermansen, J.E.. Many current organic arable agriculture systems are challenged by a dependency on imported livestock manure from conventional agriculture. At the same time organic agriculture aims at being climate friendly. A life cycle assessment is used in this paper to compare the carbon footprints of different organic arable crop rotations with different sources of N supply. Data from long-term field experiments at three different locations in Denmark were used to analyse three different organic cropping systems (‘Slurry’, ‘Biogas’ and ‘Mulching’), one conventional cropping system (‘Conventional’) and a “No input” system as reference systems. The ‘Slurry’ and ‘Conventional’ rotations received slurry and mineral fertilizer, respectively, whereas the ‘No input’ was...

Ano: 2013 URL: http://orgprints.org/23069/13/23069.pdf Livscyklusvurdering af økologiske og konventionelle planteavlssædskifter - fokus på drivhusgasemissioner Organic Eprints Knudsen, Marie Trydeman; Olesen, Jørgen E.; Hermansen, John E.; Meyer-Aurich, Andreas. Life cycle assessment of organic and conventional arable crop rotations - focusing on greenhouse gas emissions. Five arable crop rotations in long-term field trials were investigated; four organic and one conventional - in three years on three different locations in Denmark. The organic crop rotations represented alternative scenarios for outphasing conventional slurry in organic systems. Crops from rotations with grass-clover for biogas in one out of four years had the lowest carbon footprint per kg crop DM. Including soil carbon changes in the life cycle assessment affected the results markedly.
