Erstellung einer aktuellen Datensammlung für Planung und Controlling zu allen wichtigen Betriebszweigen und Produktionsverfahren im Ökologischen Landbau: Teilstudie Ökologischer Gemüsebau Organic Eprints
Arbeitskreis Betriebswirtschaft im Gartenbau, e.V..
Bedingt durch die politische Entwicklung der letzten Jahre hat der ökologische Anbau in Deutschland an Bedeutung gewonnen. Für eine Ausdehnung, bzw. Förderung des ökologischen Anbaus fehlen allerdings Daten, die umstellungsinteressierten Betrieben bei der Entscheidungsfindung behilflich sein können. Ebenso fehlen ökologisch wirtschaftenden Betrieben Daten zur Kontrolle der eigenen Leistung. Diese Datensammlung hat zum Ziel, Kosten-Leistungsrechnungen zu typischen Produktionsverfahren der zehn wichtigsten Kulturen des ökologischen Gemüsebaus in Deutschland bereitzustellen, um so die genannten Informationslücken zu schließen. Die zehn in Bezug auf die Fläche und den Umsatz wichtigsten Kulturen wurden durch Berater des ökologischen Gemüsebaus...

Umstellung auf Vollweidehaltung mit Kurzrasenweide am Beispiel eines Praxisbetriebes aus Oberbayern Organic Eprints
Linner, Alfons; Trei, Gerriet; Hörning, Prof. Bernhard.
Aim of the study was to demonstrate the principles of a low-input system for dairy cows (“full pasture system”) using an existing organic farm as an example (case study). This system might be well suited for organic farms (low use of concentrates, natural behaviour at pasture, etc.). Experiences of the conversion of the first summer at the farm were documented (changes in milk ingredients, grass development).

Biotoppflege als neue Funktion und Leistung der Tierhaltung Organic Eprints
Rahmann, Gerold.
Biotopbeweidung mit der Leistung Pflege kann als neue Funktion der Tierhaltung verstanden werden. Die „Biotoppflege mit Nutztieren“ ist dabei eine spezielle Ausprägung der „Kulturlandschaftspflege mit Nutztieren“, die sich vor allem auf den biotischen (Flora und Fauna) und weniger auf den ästhetischen (Landschaftsbild) und abiotischen Schutz (Wasser, Boden, Luft) bezieht. Sie stellt eine tiergebundene Nutzung geschützter Grünlandstandorte dar, insbesondere der verschiedenen Ausprägungen der Magerrasen und des Feuchtgrünlandes, und kann als „pflegende Nutzung“ bzw. „nutzende Pflege“ geschützter Biotope verstanden werden. Obwohl eine Reihe von Biotopen durch jahrhundertelange Beweidung geprägt wurden, ist sie als gezieltes Instrument der Pflege relativ...

Organic milk production: post conversion phase - IGER OF0113 Organic Eprints
Unspecified,.
The main objective of the current project was to improve the understanding of the factors affecting both the physical and financial performance of dairy farms in the post-conversion phase and to compare their performance with comparable conventional dairy farms. An additional objective was to provide a framework for the development and sustainment of organic milk production. The project was based at the Ty Gwyn organic dairy farm at IGER Trawsgoed with ten linked commercial dairy farms also monitored during the study. These farms ranged in size from 45 to 450 ha with the size of the dairy herds ranging from 45 to 260 cows. Among the factors studied during the project were changes in the soil indices, with particular reference to the P and K concentrations...

Eating quality of Holstein bull calves fed only grass or purely herbs matches that of concentrate-fed veal calves Organic Eprints
Therkildsen, M.; Jensen, S.K.; Vestergaard, M..
Organic meat production from Holstein calves born in dairy herds require that the bull calves are raised outdoor at least 6 months a year, and on large quantities of roughage in the diet. This study aimed at elucidating if Holstein bull calves fed either purely grass or purely herbs prior to slaughter would differ in meat quality traits, fatty acid composition and sensory profile and if they differed in quality aspects from concentrate-fed veal calves.

Milk yield, udder health and reproductive performance in Swedish organic and conventional dairy herds Organic Eprints
Fall, Nils; Emanuelson, Ulf.
Organic dairy farming is an expanding segment of the dairy sector where cow management differs from the conventional model in many respects. Thus, a comparative evaluation of disease and welfare status in organically and conventionally managed dairy cows is required. Assessment of milk yield, udder health and reproductive performance (RP) was done in 20 organically and 20 conventionally managed Swedish dairy herds. In accordance with earlier findings we confirmed lower milk yield in organic cows. Udder health and RP were chosen as indicators of animal health in view of their clinical relevance and the availability of appropriate data bases providing good background knowledge for further animal health assessment. No obvious differences were found in the...

Sensitivity of soil phosphorus tests in predicting the potential risk of phosphorus loss from pasture soil Organic Eprints
Soinne, Helena; Saarijärvi, Kirsi; Karppinen, Minna; Hartikainen, Helinä.
The objective of this study was to examine the effects of urine and dung additions on the phosphorus (P) chemistry of pasture land and to compare the sensitivity of two soil extraction methods in assessing the P-loading risk. In a field experiment, urine and dung were added to soil in amounts corresponding to single excrement portions and the soil samples, taken at certain intervals, were analysed for pHH2O, acid ammonium acetate extractable P (PAc) and water extractable total P (TPw), and molybdate reactive P (MRPw). Urine additions immediately increased soil pH and MRPw, but no such response was observed in PAc extraction due to the low pH (4.65) of the extractant enhancing the resorption of P. The PAc responded to the dunginduced increase in soil total...

Potential of Near Infrared Spectroscopy for differentiation of organically and conventionally produced milk Organic Eprints
Aulrich, Karen; Molkentin, Joachim.
Der ständig wachsende Marktanteil ökologisch erzeugter Milch erfordert leistungsstarke und zuverlässige Methoden zur Herkunftssicherung der Milch. Die Zusammensetzung der Milch, speziell die Gehalte an ω3-Fettsäuren (FS) werden im Wesentlichen durch die Fütterung beeinflusst. Deshalb wurde die NIRS als mögliche Alternative zur Gaschromatographie (GC) für die quantitative Analyse der FS bewertet und ihre Eignung für die Unterscheidung von ökologisch und konventionell produzierter Milch geprüft. Um variable Effekte der Fütterung einschließlich saisonaler Effekte aufzuzeigen, wurden zwei konventionell und eine ökologisch erzeugte Markenmilch im zweiwöchigen Abstand über 18 Monate im Einzelhandel gekauft. Zusätzlich wurde im gleichen Intervall eine ökologisch...

Comparing energy use and greenhouse gas emissions in organic and conventional farming systems in the Netherlands Organic Eprints
Bos, J.F.F.P.; de Haan, J.J.; Sukkel, W.; Schils, R.L.M..
Results are presented of a model study comparing energy use and greenhouse gas emissions in organic and conventional farming systems in the Netherlands. Calculations have been performed for model farms, designed on the basis of current organic and conventional farming practices. Energy use and greenhouse gas emissions per hectare on organic farms are lower than on conventional farms, particularly in dairy farming. Energy use and greenhouse gas emissions per Mg of milk in organic dairy farming is about 80 and 90%, respectively of that in conventional dairy farming. Energy use and greenhouse gas emission per Mg product in organic crop production is 5-40 and 7-17%, respectively higher than in conventional systems. The wide ranges found in crop production...

Wirksamkeit einer Behandlungsmethode zur Vorbereitung von Rindern auf Transport und Schlachtung und deren Auswirkung auf Verhalten, Blutparameter und Fleischqualität Organic Eprints
Probst, Johanna; Leiber, Florian; Hillmann, Edna; Spengler Neff, Anet.
Das Ziel der hier vorgestellten Untersuchung war, einen ersten Schritt hin zur Entwicklung einer praxistauglichen Behandlung von Mastbullen zu tun, welche deren Stressreaktionen während des Verladens, Transportes und Aufenthaltes im Schlachthof reduziert. Die Ausgangshypothese war,dass Vertrautheit mit Menschen sowie positive Erfahrungen bei der Berührung durch Menschen dazu führen, dass die Tiere während des Verladens und des Transportes weniger Belastungsreaktionen zeigen. Die Annahme war ferner, dass sich dies sowohl im Verhalten, als auch in metabolischen Parametern und schliesslich in der Fleischqualität zeigt.

Mikromineralinnhold i jord og planter - mikromineralforsyning til drøvtyggere i økologisk landbruk Organic Eprints
Strøm, Turid; Hansen, Sissel; Govasmark, Espen.
For alle mineralene unntatt klor var det et høgere innhold i 2. slått enn i 1. slått. Flere av planteprøvene viste så lavt innhold av ett eller flere makromineral at det antagelig reduserte avlingsnivået. Ut fra mineralbehovet hos sau og storfe viste plante- og blodprøver at flere av besetningene hadde liten tilførsel av svovel, fosfor, selen og E-vitamin, mens tilførselen av magnesium, kobolt og kopper var tilfredsstillende. Videre bearbeidelse av innsamla datamateriell og utprøving av ulike selentilskudd til jord og planter vil danne grunnlaget for å trekke endelig konklusjoner i forskningsprogrammet, samt utarbeide praktiske råd om mineraltilførsel til planter og drøvtyggere i økologisk landbruk.

Drought Tolerance and Perennial Weed Management Organic Eprints
Nkurunziza, Libère; Andreasen, Christian; Liu, Fulai; Streibig, Jens Carl.
The aim of this study was to investigate the effect of controlled soil water deficits on sprouting and shoot growth of Canada thistle, coltsfoots and quackgrass. A gradient of soil water contents was created by establishing different densities of barley. The plants were harvested 14 days after watering was stopped. On Canada thistle and coltsfoots, relative water content (RWC) in leaves was measured prior to harvest and biomass of all weed shoots were recorded at harvest. In terms of shoot biomass and leaf RWC quackgrass was drought tolerant while coltsfoot was drought sensitive and Canada thistle was between the two. The barley cover crop could have had a competitive effect upon the growth of the weeds; the effect, however, was not detrimental compared to...

Concentrations of soil potassium after long-term organic dairy production Organic Eprints
Løes, Anne-Kristin; Øgaard, Anne Falk.
On five long-term organic dairy farms aiming at self-sufficiency with nutrients, soil concentrations of ammonium-acetate lactate extractable potassium (K-AL) and acid-soluble K was measured twice in topsoil (0-20 cm) and subsoil (20-40 cm) over periods of 6-14 years. Organic management had occurred for >9 years at the second sampling. On average there were most probably field level K-deficits. Even so, topsoil K-AL concentrations were medium high (65-155 mg K kg–1 soil), and did not decrease during the study period. However, for three farms, topsoil K-AL was approaching a minimum level determined by soil texture, where further decrease is slow. Subsoil K-AL concentrations were generally low (<65). The soils were mostly light-textured, and reserves of...

Schurft optimaal bestrijden met een minimale hoeveelheid koper Organic Eprints
Hemelrijck, Wendy.
Door de mogelijke schadelijke effecten, bv. door een te hoge hoeveelheid aan koper in de bodem, staat het gebruik van koper in de land- en tuinbouw ter discussie, ook in de biologische teelt van pitfruit. Desondanks de vele studies zijn er tot op heden nog geen andere middelen ter beschikking om koper te vervangen. Tot op heden is het weglaten van preventieve koperbehandelingen uit de managementstrategie naar schurft in de biologische teelt dus ondenkbaar. Toch worden vanuit de Biovakgroep pitfruit inspanningen gedaan om het gebruik van koper te doen dalen indien mogelijk. Daarom werd, in samenwerking met de Biovakgroep pitfruit, een project uitgevoerd waarin werd nagegaan of er voor de beheersing van schurft bij Conference kan gebruik gemaakt...
