Ackerbauliche Auswertung von Praxiserhebungen in Beständen  verschiedener Körnerleguminosen: Erste Ergebnisse zu Unkraut und Bestandesdichte
Provedor de dados: 21
Autores: Schmidt, H.; Langanky, L.
Data of approx. 325 organic and conventional grain legume fields between 2015 and 2018 will be analysed regarding agronomic issues. On this selection of farms that are  involved in the exemplary demonstration networks of the German governments protein crop strategy additionally to the data collected in the network, management information  will be evaluated and various soil and plant parameters will be measured. The main goal is the identification of agronomic factors influencing the success of the grain  legume cultivation. First results show the higher weed pressure and the closer connection of weed cover ratio and legume plant density in organic compared to conventional systems.

Must Organic certification fundamentally change for an Organic World?

Autores: Soto, G.; Herrmann, G.A.; Schmidt, H.; Montenegro, L.; Zuck, L.
Organic guarantee systems have evolved drastically in the past, accompanying changes in the uptake of Organic agriculture. From an originally fully stakeholder-driven and participatory process in the '70s and '80s, organic certification has become increasingly formalized and government-controlled. organic certification is a must-have for organic market access in more and more countries in the world, but is often not seen by producers to add much value beyond that. It claims to bring transparency and trust to the consumers, but it also delegates the judgment of agricultural practices to more or less anonymous entities. Certification is not designed to prevent fraud but it is expected to control and detect it. Organic certification and regulations are...

Treibhausgasflüsse beim Anbau von Winterweizen und Kleegras
Provedor de dados: 21
Autores: Peter, J.; Schmidt, H.; Schilling, R.; Munch, J.C.; Hülsbergen, K.-J.
At the experimental station Viehhausen, 30 km north of Munich in southern Germany, N2O, CO2 and CH4 fluxes between soil and atmosphere were measured to investigate the influence of site-related factors and cultivation-technique on the emissions of these greenhouse gases. Clover-grass as well as several wheat cropping systems (with and without biogas slurry) were analyzed under the conditions of organic farming. This paper shows the results of the vegetation period of 2009. The N2O emissions from the wheat fields were higher than those from clover-grass fields. Ploughing-in of the legume-grass biomass resulted in releasing distinctive N2O emissions. For CH4 fluxes the arable soils were a net sink, especially in cropping systems with winter wheat.
