Ecomat und Dammkultur – Alternative Bodenbearbeitungssysteme im Ökologischen Landbau – Erste Ergebnisse aus einem Exaktversuch Organic Eprints
Quintern, M.; Otto, M.; Schüler, C.; Heß, J..
In the interdisciplinary research project a field experiment of alternative tillage systems in organic farming was installed. Ridge till system from Turiel-Major and Ecomat-system from Kverneland will be compared with conventional ploughing system. Within the project, located on the experimental farm of the University of Kassel, regular yearly workshops are led. Due to the regular contact with farmers, advisers, developers and scientists knowledge of practice will be carried into scientific research, the transfer of knowledge will be carried on. The change to the Ecomat-system is simple. Take notice that after very shallow till-age, like stubble cultivation (short stubble) or turning grass-clover, the following tillage has to be done a few cm deeper. In...

Ermittlung der Futterqualität verschiedener Wintererbsengenotypen in Rein- und Gemengesaat zur Nutzung als nachwachsender Rohstoff, als Grünfutter und als Druschfrucht Organic Eprints
Urbatzka, P.; Graß, R.; Schüler, C.; Heß, J.; Schliephake, U.; Trautz, D..
Normalblättrige Wintererbsen sind in Reinsaat eine rohproteinreiche Winterzwischenfrucht für die Nutzung als Grünfutter oder als nachwachsender Rohstoff zur Energiegewinnung im Rahmen von Zweikulturnutzungssystemen. Zum Korndrusch im Gemengeanbau stellen sie bei mindestens vergleichbaren Kornerträgen und Qualitäten eine Alternative zu Sommererbsen dar. Dabei können Anbauprobleme von Sommererbsen besonders hinsichtlich der Unkrautregulierung reduziert werden.

Ermittlung der Vorfruchtwirkung unterschiedlicher Wintererbsengenotypen in Rein- und Gemengesaat Organic Eprints
Urbatzka, Peer; Graß, Rüdiger; Schüler, Christian; Heß, J..
In organic farming the cultivation of leguminous crops is one of the most important sources of nitrogen (N). However, in the case of winter field peas, the amount of N fixed, N supply to the subsequent crop and N balance there are hardly any published data. Therefore, the pre-crop effect of six genotypes of winter pea (five regular leaf type, one semi-leafless cultivar) and one semi-leafless spring pea cultivar in single and mixed cropping (with rye spring barley respectively) was examined in three suc-cesive growing seasons (2003/04-2005/06). Immediately after harvest, a catch crop was sown and sampled during the first half of October to determine biomass dry matter and N uptake. In single cropping, N uptake by the catch crop was usually significantly...

GemüseSelbstErnte: Weiterentwicklung und Transfer sowie Ermittlung des Beitrags zur Gesundheitsförderung Organic Eprints
Heß, J.; Meier-Ploeger, A.; Hamm, U. (Hrsg.).
Ziel des Projekts „GemüseSelbstErnte – Weiterentwicklung und Transfer sowie Ermittlung des Beitrags zur Gesundheitsförderung“ war es das Konzept der GemüseSelbstErnte bekannt zu machen und weiter zu entwickeln (Transfer). Zusätzlich wurden die Verbundeffekte für die Direktvermarktung quantifiziert und die Auswirkungen auf das Ernährungsverhalten der Nutzer überprüft (Forschung). Transfer Der Kenntnisstand von Erzeugern, Beratern und Verbrauchern über die GemüseSelbstErnte konnte mit einer intensiven Öffentlichkeitsarbeit, die zwei Messeauftritte (u.a. auf der IGW 2004), acht Vorträge, elf Fachartikel und drei Workshopangebote mit insgesamt 36 Teilnehmern umfasste, deutlich verbessert werden. 170 Personen forderten Informationsmaterial an. Außerdem...

Legehennen in einem mobilen Stallsystem - Auslaufnutzung und Flächenzustand - Organic Eprints
Fürmetz, A.; Keppler, C.; Knierim, U.; Deerberg, F.; Heß, J..
The use of the free-range area by laying hens housed in a mobile system and the resulting condition of the range were investigated. The free-range was used very intensively. On an average of nine complete observation days 35 % of the birds (23 – 44 % means per day) were outside the house. The maximum of animals in the free range was 77 %. 75 % (60 – 95 %) of the hens outside the house stayed in an area of 20 m around the house. This led to deteriorated conditions of the range in these areas. By moving the mobile house regularly (after 2 weeks in summer and 6 weeks in winter) a destruction of the vegetation could be avoided, while after not moving the house for three months in winter a complementary seeding became necessary. We conclude that the use of...

Legehennen in einem mobilen Stallsystem - Flächenmanagement und resultierende Stickstoffgehalte im Auslauf - Organic Eprints
Fürmetz, A.; Keppler, C.; Knierim, U.; Deerberg, F.; Heß, J..
In the last years free range poultry was often criticised for its negative impacts on environment. As the animals do not use the run equally, a big part of the excreted nutrients are accumulated in the area close to the poultry house. This can lead to an increased rate of nutrient loss especially nitrogen by leaching. Within this study the use of a mobile housing system for 1.000 layers on an organic farm in North Hessia with a mean of 700 mm precipitation per year and an average of 8,9°C (soil texture: loam in the first, silt loam in the second year) was observed for two years. A documentation and optimization of the management and regular investigations into the contents of mineral nitrogen in all parts of the outdoor run were carried out. The aim of...

Ökologischer Kreislauf Moorbad Harbach: Life Cycle Assessment (LCA) for Agricultural Plant Production and Transportation Organic Eprints
Kratochvil, R.; Fromm, E.; Heß, J.; Freyer, B..
In 1992 the community of Moorbad Harbach (Austria), located near the border of the Czech Republic and dominated by extensive agricultural practice on small scale farms, decided to initiate activities for regional devolopment. About 40 farms (27 %) converted to organic farming, a local marketing service as well as regional food processing businesses (slaughterhouse, dairy), operating as linkages between regional agriculture and the local spa hotel were founded. The basic idea for the work presented here was to evaluate the – especially ecological – consequences of such a regional conversion. One part of this attempt of evaluation was carried out as a LCA for the agricultural production in Moorbad Harbach. The emphasis of the study was to compare plant...

Organic Farming in Austria Organic Eprints
Vogl, C. R.; Heß, J..
During the present decade, Austria has experienced a dramatic increase in organic farming among those countries that comprise the European Union (EU). For example, in 1992, approximately 2,000 farms were practicing organic, ecological, or biodynamic farming methodes. By 1997 the number of certified organic farms plus those in transition from conventional farming had increased 10-fold to some 20,000 farms. This represents almost 9% of the total farms in Austria and an area of 345,375 ha, or 10% of the total cultivated farmland. The largest concentration of organic farms is in regions with a high proportion of alpine grassland or pastures. Approximately 50% of the organic farms range in size from 5 to 15 ha. The strong organic movement in Austria can be...

Samenfeste Sorten oder Hybriden - Anbauvergleich von Möhren unter den Verhältnissen des Ökologischen Landbaus Organic Eprints
Fleck, M.; Sikora, F.; Gränzdörffer, M.; Rohmund, C.; Fölsch, E.; von Fragstein, P.; Heß, J..
A field trial with carrots was carried out in 1998 at two sites in Hesse (North: loamy soil in Neu-Eichenberg; East: sandy soil in Queck) to compare 6 open pollinating and 6 F1 hybrids under an Organic Farming regime. Characteristics of cultivation, harvest, quality, and longevity were measured. Of the parameters of cultivation and harvest the hybrids showed a more intensive foliage growth, higher marketable yields (plus 29 and 25%), and more homogeneous taproots than the open pollinating cultivars. Picture forming methods clearly separated the samples into the two groups of breeding methods. The open pollinating cultivars were characterized by higher degrees of form intensity and ripeness and a stable vitality. The hybrids of the sandy site had a better...

Samenfeste Sorten oder Hybriden - Untersuchungen an Speisemöhren aus einem Anbauvergleich an zwei Standorten des Ökologischen Landbaus Organic Eprints
Fleck, M.; Sikora, F.; Rohmund, C.; Gränzdörffer, M.; von Fragstein, P.; Heß, J..
An zwei Standorten des Ökologischen Landbaus (Neu-Eichenberg, Nordhessen: mittlerer bis schwerer Boden; Queck, Osthessen: leichter Boden) wurden Feldversuche mit Möhren durchgeführt, um sechs samenfeste Sorten und sechs Hybriden auf ihre Anbautauglichkeit zu prüfen. Außer der Roh- und Handelswarenerträge wurden die Einheitlichkeit des Erntegutes (cv%) bestimmt und die Gehalte an Mineralstoffen (K, Ca, P, Mg) und Zuckern (D-Glucose, D-Fructose, Saccharose) analysiert. Auch sogenannte Bildschaffende Methoden (Kupferchloridkristallisation, Steigbild, Rundfilterchromatogramm) kamen zur Anwendung. Die untersuchten Hybriden erzielten Mehrerträge von 25 bis 29% und in den meisten Fällen auch gleichmäßiger lange Rüben als die Samenfesten. Die...
