Analyse Intégrée de la DYnamique des systèmes biophysiques, techniques et de décision lors de la conversion à la viticulture biologique. Organic Eprints
Les conversions en Agriculture Biologique (AB) se développent rapidement en viticulture, surtout dans les vignobles méditerranéens (+ 20% entre 2006 et 2008 d’après l’Agence Bio) sans que les connaissances et les outils permettant d’accompagner cette rupture ne soient opérationnels. Ce projet vise à combler cette lacune en faisant l’hypothèse qu’une approche intégrée des dynamiques biophysiques, techniques, économiques et organisationnelles encadrant la phase de conversion à l’AB (avant, pendant les 3 ans réglementaires et après) permet d’assurer une plus grande durabilité de cette innovation de rupture (Lamine et Bellon, 2009). Ce cadre finalisé offre une opportunité de travailler,sur les questions scientifiques relatives à la caractérisation de la...

Analýza ekologického hospodaření na orné půdě Organic Eprints
Moudry, Jan (Jr.); Moudry, Jan; Rozsypal, Roman.
Studie je zaměřena na posouzení struktury ekologicky hospodařících podniků a na indikaci faktorů ovlivňujících rozvoj ekologického zemědělství na orné půdě. Analýza struktury zemědělských podniků byla provedena na dvou testovacích souborech. Bylo prokázáno, že s přibývající nadmořskou výškou roste extenzita hospodaření, výrobní struktura podniku se zjednodušuje (zatravnění v kombinaci s chovem skotu BTPM). Při konverzi na ekologické zemědělství přistupují až ke stoprocentnímu zatravnění, což vyvolává utlumení produkčních zemědělských funkcí. S rostoucí nadmořskou výškou klesá podíl orné půdy. V nedostatečné míře jsou zastoupeny zlepšující plodiny (brambory, pícniny na orné půdě a luskoviny). Existence řady ekologicky hospodařících podniků závisí na...

Anforderungen des Ökologischen Landbaus an die Agrarökonomie. Hinweise für die gartenbauliche Forschung Organic Eprints
Dabbert, S..
Die Agrarökonomie als Wissensgebiet definiert sich durch den empirischen Gegenstand und einen Methodenkanon. Das institutionelle Netzwerk der Agrarökonomie erstreckt sich über Universitäten und Fachhochschulen, außeruniversitäre Forschungseinrichtungen, Verwaltungen, den gesamten agrarwissenschaftlichen Sektor und die verschiedenen Interessenverbände. Zu den Anforderungen des ökologischen Landbaus an die Agrarökonomie gehört zum einen ein Verständnis für das Gesamtsystem des Öko-Anbaus. Zum anderen besteht jedoch auch die Notwendigkeit der deskriptiven Forschung. Es müssen viele Zahlen, die im konventionellen Bereich bereits vorliegen, neu zusammengetragen werden. Betriebswirtschaftliche Forschung im Bereich des ökologischen Gemüsebaus gibt es bisher...

Animal Husbandry Practices of Organic Farmers: An Appraisal Organic Eprints
Bodapati, Subrahmanyeswari; Chander, Mahesh.
In Uttarakhand organic farming is being promoted through a special institution i.e. Uttarakhand Organic Commodity Board (UOCB) through registering the farmers and orienting them towards organic farming. Organic farmers currently practicing and marketing only organic crop products. However, their livestock production practices are also similar to recommended organic standards. Hence, to document their livestock production practices, a total of 180 registered organic farmers selected through multistage sampling technique studied during 2006-07. Cent percent of registered organic farmers were involved in mixed farming enterprises and most of them were with more than one livestock species (farm diversity). The breeds maintained by these farmers were of...

Animating Multicriteria Decision-making Processes in the Organic Value Chain Organic Eprints
Kastberg, Peter.
When thinking about animations, an intuitive reaction could be to dismiss them as mere children’s pastime, but that is by no means the whole picture. Animated films featuring highly specialized knowledge from, say, the domains of science, technology and engineering are to be found all over the current media landscape. There is a tendency that they are predominantly used in one specific communicative constellation, i.e., when domain-specific knowledge is communicated from an expert or authority to a lay person. That, too, is the case when it comes to the animated film “MultiTrust” (to be found here: http://www.youtube.com/watch?v=zmoXYJAS8LY ). This animation stems from the research project “Multicriteria assessment and communication of effects of organic...

Anthelmintic effects of forage chicory (Cichorium intybus) against gastrointestinal nematode parasites in experimentally infected cattle Organic Eprints
Peña-Espinoza, Miguel; Thamsborg, Stig Milan; Desrues, Olivier; Hansen, T. V. A.; Enemark, Heidi L..
Two experiments studied the effects of dietary chicory against gastrointestinal nematodes in cattle. In Experiment (Exp.) 1, stabled calves were fed chicory silage (CHI1; n = 9) or ryegrass/clover hay (CTL1; n = 6) with balanced protein/energy intakes between groups. After 16 days, all calves received 10 000 Ostertagia ostertagi and 66 000 Cooperia oncophora third-stage larvae (L3) [day (D) 0 post-infection (p.i.)]. In Exp. 2, calves were assigned to pure chicory (CHI2; n=10) or ryegrass/clover (CTL2; n = 10) pastures. After 7 days, animals received 20 000 O. ostertagi L3/calf (D0 p.i.) and were moved regularly preventing pasture-borne infections. Due to poor regrowth of the chicory pasture, CHI2 was supplemented with chicory silage. At D40 p.i. (Exp. 1)...

Antibiotic use by farmers to control mastitis as influenced by health advice and dairy farming systems Organic Eprints
Poizat, Axelle; Bonnet-Beaugrand, Florence; Rault, Arnaud; Fourichon, Christine; Bareille, Nathalie.
Mastitis is a bacterial disease common in dairy farms. Although knowledge about mastitis and its optimal technical management and treatment is now available, some dairy farmers still use antibiotics in inappropriate ways. Antibiotic use by farmers can be influenced by personal restraints and motivations, but it can be assumed that external drivers are also influential. The main purpose of this article is thus to analyse the choices of antibiotic and alternative medicine use for mastitis treatment and investigate the possible influence of two unexplored external drivers in dairy farms: (i) the health advice offered to farmers by farm advisors and veterinarians, (ii) the dairy farming system, as defined by combining the market valuation chosen for the milk,...

Antropização da zona de amortecimento da reserva biológica serra dos toledos (Itajubá-MG) e seu efeito na qualidade do solo. Organic Eprints
LIMA, Olivia de; MELLONI, Rogério; MELLONI, Eliane Guimarães Pereira.
Areas that comprise “damping zones” are important in minimizing the effects of impacts on the environment as they can affect the conservation unit, and in helping to maintain its natural resources. However, they are not protected and many are handled improperly, compromising the sustainability of the conservation units they should protect. The aim of this study was to evaluate the effect of human disturbance in the damping zone on the soil quality inside the Biological Reserve Serra dos Toledos,Itajubá-MG. For this, there were selected three areas under different activities in the damping zone (pasture, agriculture, and native forest) and three areas sided to those, within the Reserve. They were characterized according to various physical,...

Application of lactic acid bacteria in green biorefineries Organic Eprints
Lübeck, Mette; Lübeck, Peter Stephensen.
Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant...

Arbeitspferde im biologisch-dynamischen Gemüsebau - Zusammenfassung einer Projektarbeit Organic Eprints
Strüber, Klaus.
In einer norddeutschen Demeter-Gärtnerei wurden 2003 versuchsweise Arbeiten in Gemüsepflege, Grundbodenbearbeitung und Futterbau mit Zugpferden statt Schleppern durchgeführt. Dabei wurden die Kosten der Pferdehaltung und der Geräte erfasst sowie deren Leistungen. Zum Projekt gehörte ein Rechts/Links-Versuch zu Verdichtungen als auch Bearbeitung von Anfragen und Öffentlichkeitsarbeit. Die Pferdearbeit wurde nach dem Projekt im Betrieb fortgesetzt, die Qualität der Arbeit war sehr gut, in den Leistungen war das Pferd insgesamt langsamer als der Schlepper. Auf den Boden wirkt das Pferd sich günstig aus. Unter klaus.strueber@web.de kann der Gesamtbericht angefordert werden.

Arbeitszeitbedarf für die Betreuung von Biogasanlagen Organic Eprints
Wagner, Andrea; Juschkat, Michaela; Heitkämper, Katja; Stadelmann, Monika; Hartmann, Stefan; Schick, Matthias.
The working time requirement for different methods of biogas production forms the basis for a full cost calculation as well as for the planning of working capacities in biogas plant management. The aim of this study is to quantify the time requirement under different conditions. An ergonomic analysis was carried out for ten biogas model plants which differed in terms of gas utilisation and installed capacity as well as of substrate usage (energy feedstock and mass) and plant size. The results of the model calculations yielded a total working time requirement of between 679 and 2,140 MPh/year for the ten model plants from an electrical output of 75 kW to a gas supply of 700 m3 under normal conditions. The time required for feeding a plant increases in...
