Das Grünland des Ökologischen Landbaus in Bayern Ergebnisse aus dem Grünlandmonitoring Bayern Organic Eprints
Mayer, Franziska; Kuhn, G.; Heinze, Sanna.
The Bavarian Grasslandmonitoring (Bavarian grassland survey) included more than 6000 grassland sites of different farming intensities and geographical and climatic conditions in the first survey 2002-2008. Substantial information on species number and composition was provided in a high spatial resolution. To investigate the changes in vegetation, 2485 of the vegetation surveys were repeated between 2009 and 2012, 350 of them with organic farming. On each plot of 25 m² the species composition and the proportion of total yield of each species were documented. On average 20 species were recorded per 25 m² plot; a total number of 632 plant species was found all over the 2485 grassland plots. Comparing the first and the second survey the grassland vegetation...

Reversion from organic to conventional agriculture in Germany Organic Eprints
Heinze, Sanna; Vogel, Alexander.
Organic farming has become increasingly important in Germany in recent years. This is reflected in the positive trend shown by the total number of organic farms. Analyses which are based on official agricultural statistics show, however, that there is an underlying counter-trend of farms that leave the organic sector by reverting back to conventional methods. Between 2007 and 2010 1,258 German organic farms returned to conventional agriculture. This paper aims to offer an overview, how many and what types of farms actually abandon organic farming in Germany. Probit-estimations are used to identify first indications for determinants of reversion from organic to conventional agriculture.
