Biotic and abiotic binding and bonding mechanisms in soils with long-term differences in management Organic Eprints
Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia; Schjønning, Per.
During the last decades Denmark has experienced a growing interest in low-input farming systems like organic farming. These systems rely on a high soil fertility to maintain nutrient availability and plant health. Soil aggregation contributes to this fertility, because it is crucial to soil porosity, aeration and infiltration of water. This paper reports a study of two pairs of differently managed, neighboring fields. The aim was to elucidate long-term effects of the different farming systems on physical and biological variables with influence on bonding and binding mechanisms of soil aggregation. Each pair consists of an organically grown dairy farm soil, based on a forage crop rotation system, including grass (Org-FCS(G)) and a conventionally managed...

Organic forage seed production Organic Eprints
Boelt, B.; Deleuran, L.C..
From January 2004 only organically produced seed can be used in organic farming systems within the EU. Danish seed producers and seed companies are establishing an organic forage seed production in order to supply organic growers within the EU with high quality seed of recognised varieties. This brief paper outlines a project investigating improved cultivation and management techniques to ensure such a supply is met.

Simulating Soil Organic Matter Transformations with the New Implementation of the Daisy Model Organic Eprints
Petersen, Anders; Bruun, Sander; Jensen, Dr. Lars Stoumann; Hansen, Dr. Søren.
Daisy is a well-tested deterministic, dynamic soil-plant-atmosphere model, capable of simulating water balance, nitrogen balance and losses, development in soil organic matter and crop growth and production in crop rotations under alternate management strategies. Originally it was developed as a system of single models describing each process involved, but recently it has been developed into a framework, which can be used for implementation of several different models of each of the different processes. Thus, for example a number of different models for simulating soil water dynamics can be chosen depending on the purpose of the simulation and the availability of data for parameterisation. The sub-model simulating soil organic matter is still a fixed...

Forsknings- og udviklingsaktiviteter på området reduceret jordbearbejdning Organic Eprints
Schjønning, P.; Jørgensen, M.H.; Olesen, J.E.; Rasmussen, G.; Munkholm, L.J.; Melander, B..
Der er fra det danske landbrugserhverv formuleret ønske om, at der iværksættes en bedre rådgivning omkring gennemførelse af reduceret jordbearbejdning, herunder direkte såning (FRDK, bl.a. ved mødet i Forskningskontoret 18. januar 2001). Problemstillingen har interesse for såvel konventionelle som økologiske jordbrugere, idet reduceret bearbejdning af jorden som udgangspunkt er positivt for jordkvaliteten. Der er gennemført en lang række undersøgelser omkring reduceret jordbearbejdning og direkte såning i Danmark. En række forhold har dog til dels gjort disse resultater forældede. Det skyldes bl.a. den politisk bestemte udvikling i de dyrkede afgrøder, herunder i særlig grad sædskiftet, som har stor betydning for reduceret jordbearbejdning. De gennemførte...

Stand und Perspektiven des ökologischen Landbaus in den mittel- und osteuropäischen Ländern Organic Eprints
Köppen, Detloff.
Fazit Mit der Erweiterung der EU wird der ökologische Landbau in den Beitrittsländern zu einer effektiven Alternative der Landbewirtschaftung. Unter Berücksichtigung der spezifischen Ausgangsbedingungen ist ein Marktanteil wie in den westeuropäischen Ländern möglich. Wichtigste Maßnahmen sind: - die Schaffung der organisatorischen Voraussetzungen, - die Entwicklung des inländischen Marktes, - die Erschließung von Exportmöglichkeiten für ausgewählte Produkte. Dazu muß die gesellschaftliche Akzeptanz weiter verbessert werden.

Tierschutzanforderungen und aktuelle Entwicklungen [Requirements of farm animals in relation to animal welfare] Organic Eprints
Sundrum, Albert.
Im Zuge eines sich verändernden Bewusstseins in der Bevölkerung werden die Tierschutzanforderungen an die Haltungsbedingungen landwirtschaftlicher Nutztiere vom Gesetzgeber sukzessive erhöht. Darüber hinaus sieht eine zunehmende Zahl von Verbrauchern in guten Lebensbedingungen für die Nutztiere eine Prozessqualität, für deren subjektiven Zusatznutzen sie einen Mehrpreis zu zahlen bereit sind. Anforderungen an Haltungsbedingungen im Hinblick auf die Tiergerechtheit haben einen hohen Gesundheitszustand der Nutztiere und weitreichende Möglichkeiten zur Ausübung arteigenen Verhaltens zum Ziel. Sowohl von Seiten des Gesetzgebers als auch in Markenprogrammen werden Mindestanforderungen durch Größenordnungen einzelner technischer Indikatoren festgesetzt. Dabei...

Root Growth and Nitrogen Utilization of a Leek Crop and an Undersown Catch Crop Organic Eprints
Nielsen, Dr. Kai Lønne; Thorup-Kristensen, Dr. Kristian.
After its late harvest a leek (Allium porrum) crop will normally leave large quantities of nitrogen (N) in the soil which may be subject to leaching. A possible method to reduce N leaching losses is to establish a catch crop before the harvest of the leek crop. It was the aim of this study to investigate the effects of incorporating a catch crop in a leek crop with minimal competition and to monitor how root growth affected N availability across soil depths at different distances between catch and leek crop rows. To reduce competition between both crops leek was planted at 0.5 and 0.75 m row distances and chicory (Cichorium intybus) as a catch crop at an interrow spacing of 0.75 m. Minirhizotron glass tubes were inserted in the middle of the interrow...

Organic livestock production Organic Eprints
Sundrum, Albert.
The development towards a sustainable agriculture has been a main objective of organic agriculture from the beginning (IFOAM, 1978), and a declared objective of the newly applied EC-Regulation (1804/1999) on organic livestock production which provides a clear framework for livestock production. The leading idea is based on the voluntary self-restriction in the use of specific means of production with the objectives to produce food of high quality in an animal appropriate and environmentally friendly manner within a nearly complete nutrient farm organism (Sundrum, 1998). With regard to an environmentally friendly production, organic livestock farming is characterised by: - System-oriented approach, - Renunciation of mineral nitrogen, pesticides, growth...

Organic livestock farming – a critical review Organic Eprints
Sundrum, Albert.
Based on production guidelines, organic livestock farming has set itself the goal to establish an environmentally friendly production, to sustain animals in good health, to realise high animal welfare standards, and to produce products of high quality. By striving for these goals, organic livestock farming meets the demands of an increasing number of consumers, which are critical towards the conventional production methods. The paper gives an overview of the present state of the art in the different issues. Possibilities and limitations to perform the self-aimed goals under the basic standards of organic farming are discussed. Concerning environmental protection, the basic standards of organic farming are suited to reduce environmental pollution and...

Workshop and desk study to appraise technical difficulties associated with organic pullet rearing Organic Eprints
Gordon, S.
Background To date, Regulation (EC) 1804/1999 and UKROFS Standards allow conventionally reared pullets up to 18 weeks of age to be brought into systems of organic egg production. Pullets must be reared according to the rules laid down in Regulation (EC) 1804/1999 and according to UKROFS Standards for at least six weeks, before the eggs may be sold as organic eggs. The derogation for pullet rearing has been agreed for a transitional period expiring on 31 December 2003. If pullets are to be reared from day old in an organic system in accordance with Regulation (EC) 1804/1999 and UKROFS Standards this may potentially create a number of technical problems, which may disadvantage UK producers considering organic egg production. A series of workshops and a...

Wirtschaftlichkeit im ökologischen Marktfruchtbau in Mecklenburg-Vorpommern Organic Eprints
Gruber, H.; Ziesemer, A.; Annen, T..
Wie sich ökonomische Kennzahlen im Marktfruchtbau entwickelt haben, zeigen Ergebnisse aus Erhebungen in Referenzbetrieben des Landes Mecklenburg-Vorpommern. Zu diesem Zweck sind seit 1994 in ökologisch wirtschaftenden Betrieben Schlagkartei- und Buchführungsdaten erfasst und ausgewertet worden. In die Untersuchung wurden reine Marktfruchtbetriebe und Gemischtbetriebe mit Milchkuh- bzw. Mutterkuhhaltung einbezogen. In Mecklenburg-Vorpommern sind etwa 65 Prozent aller ökologisch wirtschaftenden Betriebe Gemischtbetriebe und 10 % bewirtschaften einen Marktfruchtbetrieb. Schwerpunkt nachfolgender Betrachtung ist der Marktfruchtbau. Dieser Betriebszweig hatte in allen Unternehmen einen vergleichbaren hohen Stellenwert und trug entscheidend zum Betriebseinkommen...

Soil mechanical behaviour of sandy loams in a temperate climate: case studies on long-term effects of fertilization and crop rotation. Organic Eprints
Munkholm, Lars J.; Schjønning, Per; Petersen, Carsten T..
Two case studies on Danish sandy loams investigated long-term effects of fertilization and crop rotation. Case Study 1 compared a diversely cropped organically farmed soil (DFG(1)) with a conventionally farmed soil predominantly growing annual crops (DFA), both receiving animal manure. In Case Study 2, a diversely cropped organically managed soil DFG(2)) receiving animal manure was compared with an almost exclusively cereal cropped conventionally farmed soil receiving no animal manure (CCC). A multi-level experimental strategy was followed to compare integrating field methods with specialized laboratory methods. Ease of tillage was described in the field and characterized using a drop shatter field test and by measuring aggregate tensile strength. Fitness...
