| Row cultivation in cereals with nitrogen-fixing crops can improve nitrogen supply in the crop rotation, while reducing nitrogen leaching. Well-established and competitive catch crops are important, they can both supply a significant amount of nitrogen to the subsequent crops and compete against the weeds. There needs to be a balance between main and catch crops – competitive main crops require early establishment of the catch crop and/or larger row distance. In a less competitive main crop, row distance can be narrower and the catch crops should be sown later. Early harvest is important to get a competitive catch crop. Well established catch crops can increase the yield of the succeeding crop, corresponding to up to 50 kg nitrogen per hectare. Well... |

| There is a need of scientific evidence on the differentiation of organic from conventional produce concerning health, nutrition and sensory related qualities (Leifert et al., 2007). Analysis of wheat from the DOK long-term system comparison trial near Basel, Switzerland (Mäder et al., 2002) showed that organic wheat differed in contents of 16 “diagnostic” proteins from conventional wheat (Zörb et al., 2009a), had higher concentrations of K+ and Mg2+ cations and lower concentrations of six amino acids, and a different seed ripening metabolism (Zörb et al., 2009b). In a previous sensory test with cooked porridge of wheat (cv. Tamaro) from the DOK trial (harvest 1999), the biodynamic samples had been preferred (Arncken et al., 2007). In the present work we... |

| The present study was performed to evaluate the concentrations of phytochemicals (carotenoids and phenolic acids) in wheat varieties grown under comparable organic and conventional conditions over three years as part of a long-term field trial. Phenolic acids of the hydroxybenzoic acid and hydroxycinnamic acid group were quantified by HPLC-DAD after extraction as free, soluble conjugated, and bound forms. Furthermore, the carotenoids lutein and zeaxanthin were determined by HPLC-DAD. There were no statistically significant differences between the two farming systems (sum of carotenoids (microg/g) for 2003, 0.91 +/- 0.55 organic vs 0.96 +/- 0.34 conventional; for 2005, 1.61 +/- 0.22 organic vs 1.33 +/- 0.19 conventional; for 2006, 0.87 +/- 0.33 organic vs... |

| In a field experiment with five different main crop rotations and fives subtypes for organic biogas systems, aggregate stability, organic carbon, total nitrogen and catalase were evaluated in the topsoil layer in spring 2010, 2011 and 2013 in a winter wheat stand. Aggregate stability was enhanced by variation of crop rotation but not on manuring with biogas slurry. Rotations with a higher percentage of legumes led to a higher aggregate stability. On the other hand catalase activity was improved by biogas slurry. |

| Zusammenfassung In der Diskussion um die Umweltwirkungen des Ökologischen Landbaus wird davon aus-gegangen, dass die Bodenerosion durch längere Bodenbedeckung sowie durch bessere Aggregierung der Böden durch Wurzeln und organische Düngung verringert wird. In ei-nem Dauerversuch, der auf die Wirkungen des Leguminosen-Managements in verschiede-nen Fruchtfolgen ausgerichtet ist, wurde die Aggregatstabilität in der obersten Boden-schicht (0-5cm) untersucht und mit anderen Bodeneigenschaften sowie Indikatoren der Kohlenstoffbilanzierung korreliert. Es wurden deutliche Differenzen in der Aggregatstabi-lität zwischen den verschiedenen Fruchtfolgen gefunden. Der bodenwirksame Kohlenstoff aus dem frischen, eingearbeiteten Pflanzenmaterial (Wurzeln, Stoppelreste,... |
