EFFECT OF AN IN-SEASON LIVING MULCH ON LEACHING OF INORGANIC NITROGEN IN CAULIFLOWER (BRASSICA OLERACEA L. VAR. BOTRYTIS) CROPPING IN SLOVENIA, GERMANY AND DENMARK Organic Eprints
Kristensen, Hanne Lakkenborg; Campanelli, G.; Bavec, Franc; von Fragstein und Niemsdorff, Peter; Canali, S.; Tittarelli, F..
Vegetables with a high nitrogen demand such as cauliflower may cause intensive leaching of nitrate to the environment in conventional as well as in organic production. In organic cropping systems, the use of an in-season living mulch may decrease the risk of nitrate leaching after harvest when left growing in the field to the end of the leaching season in spring. The aim of this study was to investigate the effect of growing an in-season living mulch including legumes on the risk of leaching of inorganic nitrogen over winter, and soil nitrogen availability the following spring. Three field experiments were carried out in Slovenia, Germany and Denmark in the frame of the Interveg project (CORE organic II). Evaluation of soil inorganic nitrogen content was...

EFFECT OF LIVING MULCH ON PEST/BENEFICIAL INTERACTION Organic Eprints
Burgio, Giovanni; Kristensen, Hanne L.; Campanelli, Gabriele; Bavec, Franc; Bavec, Martina; von Fragstein und Niemsdorff, Peter; Depalo, Laura; Lanzoni, Alberto; Canali, Stefano.
The aim of this study was to evaluate the effect of cover crops on pest/beneficial dynamics and to test the potential of living mulch on enhancing biological control against insect pests. The research, carried out in the frame of the InterVeg (Core Organic II) project, involved four European countries: Germany, Slovenia, Denmark and Italy. Three crops were tested: cauliflower, leek and artichoke. The preliminary results obtained in Italy on cauliflower, indicated that the living mulch did not affect the infestation of the cabbage butterfly, Pieris brassicae, showing no detrimental effect of this technique on pest dynamics. A very high level of parasitization against cabbage butterfly was detected either in the living mulch crop (88%) and in the sole one...

Einfluss unterschiedlicher Konkurrenzverhältnisse beim Mischanbau von Som-mergerste und Erbse auf den Kornertrag, die Kornqualitäten und der symbiontischen N2-Fixierung Organic Eprints
Dahlmann, Christoph; von Fragstein und Niemsdorff, Peter.
Field experiments with spring barley (Hordeum vulgare L.) and field pea (Pisum sativum L.) were carried out in three subsequent growing seasons 2004 to 2006 at the Hessian State Estate Frankenhausen located near Kassel in Central Germany. Spring barley and field pea were sown out as sole crops and intercropped with different seed rates in replacement and additive design, using two sowing modes: row by row (IC) and mixed intercropping (MC). Intercropping (IC and MC) was able to increase grain yield in most of the treatments. The Land Equivalent Ratio (LER) was always higher than 1, indicating that plant growth factors were used more efficiently by the intercrop than by the sole crop. Besides, the N content in spring barley grain was increased by...

Förderung multi-funktionaler Vorteile von Untersaat-Gemüse-Mischanbau Organic Eprints
von Fragstein und Niemsdorff, Peter.
The multifunctionality of living mulch systems was the underlying research question for field trials with cauliflower (Brassica oleracea L. convar. Botrytis) and leek (Allium porrum L.). Field trials were conducted at the Hessian Research Estate Frankenhausen over 3 years, parallel demonstration plots were established over 2 years on commercial pilot farms for entomological investigations in a big scale mode, plots of 1000 m². In all trials white clover (Trifolium repens L.) was used as a single species living mulch. In the years 2012 and 2013 the experimental design consisted of a 2-factorial approach for the test of 3 cultivars and the effect of additive and substitutive system for the establisment of living. The cultivars of cauliflower were Chambord...

Influence of different seed rates, sowing techniques and N supply on grain yield and quality parameters in intercropping systems Organic Eprints
Dahlmann, Christoph; von Fragstein und Niemsdorff, Peter.
Abstract - Field experiments with spring wheat and faba bean were carried out at the Hessian State Estate Frankenhausen located near Kassel in Central Germany in 2003 - 2005. As part of the EU Project “Intercrop”, spring wheat and faba bean were sown out as sole crops and intercropped with different seed rates, using two sowing techniques and with and without N supply. Intercropping was able to increase yield in the most treatments. All LER’s were higher than 1 and the N content in grain also increased in intercropped variants. The influence of the sowing technique was rather low in comparison to the seed rate.

Keimgeschwindigkeit, Triebkraft, Feldaufgang und Ertrag von Speisemöhren in Reaktion auf Zuchtmethode und Samengröße Organic Eprints
Fleck, Michael; von Fragstein und Niemsdorff, Peter; Heß, Jürgen.
Die Angaben aus Praktikerkreisen, dass Hybridsaatgut von Möhren per se schneller aufläuft und höhere Feldaufgänge hat als solches samenfester Sorten, konnte nicht bestätigt werden. Hier festgestellte Unterschiede im Feldaufgang hatten keinen Einfluss auf den Gesamtertrag an Rüben. Mit Blick auf die Jugendentwicklung und den Ertrag hatte die Wahl größerer Saatgutkaliber keinen Vorteil; es ist jedoch nicht auszuschließen, dass die Größe der Samen auf die Ausprägung äußerer wie innerer Qualitäten einen Effekt hat. Die Erträge der Hybriden lagen deutlich über denen der samenfesten Sorten.

Multifunktionalität von Untersaaten im Ökologischen Gemüseanbau Organic Eprints
von Fragstein und Niemsdorff, Peter.
Das Core Organic II Projekt InterVegi zielt darauf ab, untersaatbetonte Anbausysteme im ökologischen Gemüsebau in Bezug auf Vor- und Nachteile zu untersuchen. Wesentliche Parameter sind dabei Schädling-Nützling-Interaktionen, Aspekte der Beikraut-Regulierung sowie des Nährstoffmanagements, Auswirkungen auf Pflanzenentwicklung, Ertrag und Produktqualität, Umwelteinflüsse sowie ökologische Leistungen auf Feldebene. Hypothese der Untersuchungen ist: Untersaaten in Gemüsekulturen ermöglichen vergleichbare Ertragsleistungen, bessere Produktqualitäten, weniger Einsatz externer Ressourcen wie Pflanzenschutzmittel und Dünger sowie reduzierten Energie-Verbrauch. Dies führt zu Anbausystemen mit weniger Umweltbeeinträchtigung und besserer Profitabilität aufgrund...

Ökologische Landwirtschaft in den Neuen EU-Mitgliedstaaten - Ergebnisse einer Befragung zu Fruchtfolgesystemen und Nährstoffmanagement Organic Eprints
von Fragstein und Niemsdorff, Peter.
Within the EU-Project CHANNEL a status quo-analysis on organic agriculture practice was made for all new member countries, including Romania and Bulgaria as new accession countires and Austria and Germany as old member countries. Rotational and nutrient management in crop husbandry was evaluted through ques-tionnaires answered by experts of each country. Examples of typical rotations were proved with regard to duration, share of legumes and distribution of legumes. 21 of 93 rotations were shorter than 4 years and seemed to be very susceptible to unavoidable phytosanitary and compatibility problems. 20 of 93 rotations only con-sisted of non-legumes. Correspondingly the complete N management of these rota-tional systems has to be organised through...

Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems...

Organic vegetable production in Germany – status quo Organic Eprints
von Fragstein und Niemsdorff, Peter; Geyer, Bernd; Reents, Hans-Jürgen.
A survey about common practice in organic vegetable production was carried out on 100 farms in 2002 and 2003 that ranged from small to big scale vegetable holdings and reflected all important growing regions in Germany. Aspects of structure and production techniques were considered. Evaluations were made by categorizing (a) into three regional groups – South (Bavaria and Baden-Württemberg) |S|, East (New Länder) |E| and North/West (other Old Länder) |NW| - (b) into seven groups of producer organisations and (c) into eight groups of cultivation area for vegetables. The visited farms were either pure market gardens or farms with agricultural and horticultural crops or farms with or without production in greenhouses. Farms with more UAA were located in |E|...

Pea-barley intercrops use nitrogen sources 20-30% more efficiently than the sole crops Organic Eprints
Hauggaard-Nielsen, Henrik; Ambus, Per; Brisson, Nadine; Crozat, Yves; Dahlmann, Christoph; Dibet, Audrey; von Fragstein und Niemsdorff, Peter; Gooding, Mike; Kasyanova, Elena; Launay, Marie; Monti, Michele; Pristeri, Aurelio; Steen Jensen, Erik.
Field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L) were intercropped and sole cropped to compare the effects of crop diversity on the use of nitrogen sources in European organic crop-ping systems. Across a wide range of growing condi-tions pea-barley intercropping showed that nitrogen sources were used from 17 to 31% more efficiently by the intercrop than by the sole crops. Intercropping technologies offers the opportunity for organic cropping systems to utilize N complementarity between component crops, without compromising total crop N yield levels
