Ertragsentwicklung langjährig viehlos bewirtschafteter Öko- Ackerflächen am Oberrhein Organic Eprints
Recknagel, Jürgen; Nußbaumer, Helmut.
The evaluation of data from arable land in the southern part of upper Rhine valley that has been cultivated in organic agriculture without livestock since 1972 showed decreasing soil-contents of plant available P and K despite of positive fertilizer balances as well as decreasing yields of cereals on sites of lower quality. Only on a profound soil with a high level of organic substance this trend was not as marked; with autumn rye and soybeans there the yield trend was even positive (see figure 1).

Gute Chancen für den Öko-Sojaanbau in Deutschland Organic Eprints
Wilbois , Klaus-Peter; Nußbaumer, Helmut; Recknagel, Jürgen.
From 2011 to 2013 a total of 35 different soybean cultivars were tested in organically managed replicated trials under a wide range of pedo-climatic conditions in Germany. The resulting yields were affected by the climatic region, soybean maturity group, water availability during grain filling and soybean cultivar. From our results we can conclude that with current cultivars a successful soybean cropping in most parts of Germany is possible. Only in the cooler regions of northern Germany and in the uplands yields are usually not competitive with other crops.

N2-Fixierleistung von Sojabohnen und Erbsen im ökologischen Anbau Organic Eprints
Paeßens, B.; Butz, A.; Urbatzka, Peer; Recknagel, Jürgen; Mastel, K..
The aim of this study was to detect the N2-fixation of soybeans and peas in organic farming for improvement of the economic evaluation. Therefore experiments were established in Forchheim am Kaiserstuhl and Hohenkammer in 2015. The N2-fixation is calculated by the difference method after Stülpnagel with the extension III after Hauser. The results at both sites are quite different with regard to the soybeans. A much higher N2-fixation was calculated at the site of Hohenkammer, whereas the results for the peas are in a similar range for both sites.

Organic Soybean production in Europe Organic Eprints
Bernet, Thomas; Recknagel, Jürgen; Asam, Ludwig; Messmer, Monika; Borbélyné Hunyadi, Éva; Drexler, Dora.
Due to its high (40%) protein content the global significance of soybean has been constantly growing in food and feed production alike. The manual consists of relevant up-to-date information of production, processing and marketing of soybean in Europe and can be used by organic producers, processors, traders, policy makers and other stakeholders as well. Its aim is to provide basic yet comprehensive guidelines for the development of the European production and market.
Tipo: Practice tool Palavras-chave: Production systems Cereals; Pulses and oilseeds.
