| Water protection is controlled by specific regulations in the German Federal States, e.g. the SchALVO in Baden-Württemberg. An amendment of the SchALVO demands, amongst others, a changed timing and intensity of soil tillage directly after growing crops with high-nitrogen residues. As Organic Farming highly relies on soil tillage for weed control, there is concern about decrease of yield and increase of weed infesta-tion in water protection areas if tillage is restricted. Field experiments were performed on practical farms with three treatments according to SchALVO (rigid tine cultivator or mouldboard plough for primary tillage, used in October, December or February) and two treatments according to best management practice (mouldboard plough in Octo-ber or... |

| Information is rare about mustard (Sinapis alba, Brassica nigra, B. juncea) varieties and their characteristics for a suitable performance under organic conditions. 30 accessions were grown at the organic Research Station Kleinhohenheim in SW Germany in the year 2011. Highest grain yield was obtained by S. alba (10.5 g/plant) which was about four times the yield of B. nigra, and ten times the yield of B. juncea, mainly because of higher thousand kernel mass and high number of pods. B nigra and B. juncea were heavily damaged by pests so that only S. alba seems a suitable mustard species for German organic farming at the moment. |

| A long-term experiment at the Experimental Station for Organic Farming Kleinhohenheim should determine effects of stubble tillage on weed density and weed communities. The treatments were stubble tillage by a chisel plough (10 cm), a modified skimmer plough (7 cm), a rotary hoe (5 cm) and a control, previous to primary tillage by a mouldboard plough in autumn. The results presented here refer to the weed density of dicotyledonous-annual plants, monocotyledonous plants and lucerne volunteers in the years 8 and 9 of the experiment, i.e. the first two years after perennial lucerne grass. There were no significant differences found between the treatments for weeds, volunteers and crop yield of winter wheat and oats. These results confirm and continue... |

| After commercial cropping of lentils (Lens culinaris) expired in Germany 50 years ago, a revival was observed on a small regional scale. Several field trials aimed at the development of lentil cropping systems to make lentils a more popular crop in German organic farming. One of the trials was set up to identify suitable companion crops and cropping ratios for lentils in mixed cropping systems. Suitable cropping systems in terms of yield (up to 1.8 t ha-1) were combinations with barley (Hordeum vulgare), wheat (Triticum aestivum) and buckwheat (Fagopyrum esculentum) in a ratio of 180 : 60 seeds ha-1 (lentil:companion crop), and with wheat or oats (Avena sativa, 1 : 3) in terms of lodging. As lentil and wheat grains were difficult to separate after harvest,... |

| In den letzten 50 Jahren gab es nahezu keinen Linsenanbau mehr in Deutschland. Die Stickstofffixierung der Leguminose Linse, der Mischanbau und die hohe ernährungsphysiologische Wertigkeit machen den Linsenanbau attraktiv für den ökologischen Landbau. Anbautechnisch bereitet die Linse noch Probleme, z. B hinsichtlich geeigneter Sorten und optimaler Saatzeiten. Eine frühe Aussaat könnte die Vegetationsperiode verlängern und den Ertrag erhöhen, doch entfällt damit die Beikrautregulierung durch mehrfaches Abschleppen vor der Saat Auf der Versuchsstation für Ökologischen Landbau Kleinhohenheim der Universität Hohenheim wurden daher im Jahr 2009 vier Genotypen im Mischanbau mit Nacktgerste und drei Saatzeiten im Frühjahr geprüft. Linsen und die Stützfrucht... |

| Die Umstellung vom Pflug auf eine reduzierte Bodenbearbeitung wird als Möglichkeit zur Minderung des Klimawandels im Zusammenhang mit einer erhöhten Humusanreicherung diskutiert. Ob reduzierte Bodenbearbeitungssysteme im biologischen Landbau zu einer erhöhten Lachgas-Entwicklung (N2O) führen, wurde bisher nur wenig beleuchtet. Im Langzeit-Bodenbearbeitungsversuch des FiBL in Frick wurden daher N2O-Emissionen über zwei Jahre hinweg und die Humusvorräte dreizehn Jahre nach Versuchsbeginn bis in eine Tiefe von 50 cm gemessen und mit weiteren mitteleuropäischen Studien verglichen. Die kürzlich publizierte Studie von Krauss et al. (2017) zeigt, dass es bei den N2O-Emissionen in der Weizen- und Kunstwiesenperiode keine Unterschiede zwischen den... |
