| Tillage modifies soil structure and crop residue distribution and in turn affects the ability of soil micro-organisms to degrade soil organic matter and release nutrients for crop growth. In organic farming, soil microbiological activity is of primary importance as nutrient supply is mainly dependent on the degradation of soil organic matter by soil micro-organisms. The aim of this work was therefore to study, in organic farming, the effects of four tillage systems [mouldboard ploughing (MP), shallow mouldboard ploughing (SMP), reduced tillage (RT) and shallow soil tillage (ST)] on soil structure, soil microbial biomass (SMB) and its potential activity (Cmin) during the first year following the treatments. To study simultaneously the effects of soil... |

| Farming systems applying reduced tillage measures are expected to be beneficial for sustaining important soil functions (ecosystem services) and (soil)biodiversity. Furthermore a reduction in tillage intensity is connected to reduced need for energy and labour input. On the other hand waiving the plough is, especially in organic farming systems, suspected to lead to increased weed pressure and therefore decreases in yields. In this paper first results of a study on temporarily reduced tillage in organic crop-rotations are presented. Here the plough was set aside before drilling triticale at the end of four crop rotations, and expectable yields, earthworm biomass and weed pressure were investigated. First one-year-results, of the experiment on temporarily... |

| In ostösterreichischen Ackerbaugebieten ist auch im Ökologischen Landbau die viehlose Bewirtschaftungsform üblich. Der Hauptanteil des Stickstoffbedarfes wird über den Einsatz von Futter- und Körnerleguminosen sowie Leguminosen im Zwischenfruchtanbau gedeckt. Die Nutzung von Futterleguminosen erfolgt als Gründüngung, bei der der Aufwuchs am Feld verbleibt (Mulch). Die Leguminose wird als Reinkultur oder im Gemenge mit Gras angebaut. Es sollte geklärt werden, ob durch die Wurzelmasse und das tiefreichende Wurzelsystem unter Futterleguminosenbeständen die mikrobielle Biomasse bereits nach einmaligem, überjährigen Anbau von Leguminosen, v.a. im Unterboden, gefördert wird. Weiters wurde untersucht, ob Unterschiede aufgrund der Art des Nutzungsregimes (Mulch... |

| Fungal root diseases severely narrow yield in pea (Pisum sativum L.) cultivation, threatening this highly valuable protein source and important crop in low input-farming systems. Adequate resistance in current pea varieties against various root pathogens is largely lacking. The control of these pathogens is challenging, as they occur as pathogen complexes in the field, themselves embeded in entangled interactions in the rhizosphere. Plants have the ability to actively shape their rootassociated microbiome and genetic variation for rhizosphere related traits exists that can potentially be harnessed in resistance breeding. Results from a controlled pot-based resistance screening of 312 pea cultivars, advanced breeding lines and gene bank accessions on... |

| Large sized, vertical biopores can provide preferential pathways for root growth, hence facilitating the exploration of great soil depths by crop roots. This is of particular importance for organic production systems, where crops are more dependent on nutrient acquisition from the solid soil phase than under conditions of mainstream agriculture. The relevance of biopores for nutrient acquisition from the subsoil can possibly depend on their individual properties. The aim of this study was to test how different chemical pore wall properties affect the growth of barley (Hordeum vulgare L.) roots in large sized biopores. Bulk soil, pore wall material and roots from individual biopores were collected from three depth layers in 45-75 cm soil depth. C and N... |

| Pea (Pisum sativum L.) is a valuable protein source for food and feed. Pea is able to significantly improve soil fertility and, hence, represents an ecologically important crop in low-input farming systems. Despite their importance, pea cultivation remains below expectations due to low and unstable yields caused by a complex of soil-borne pathogens. The goal of this project is to improve our understanding of resistance mechanisms of pea against soil-borne diseases. To achieve this goal, more than 300 pea lines were evaluated for resistance in pot-experiments and a subset of susceptible and resistant pea genotypes has been identified. In a next step, key pathogens and beneficials in the pea rhizosphere and the role of root exudates in determining the... |

| The Tansley review by Ryan & Graham (2018) provided a welcome critical perspective on the role of arbuscular mycorrhizal (AM) fungi in large‐scale industrial agriculture, with a focus on cereals (wheat, Triticum aestivum). They conclude that there is little evidence that farmers should consider the abundance or diversity of AM fungi when managing crops. We welcome many of the points made in the paper, as they give an opportunity for self‐reflection, considering that the importance of AM fungi in agroecosystems is often taken for granted. However, we suggest that it is too early to draw the overall conclusion that the management of AM fungi by farmers is currently not warranted. We offer the following points to contribute to the discussion. The first... |
