| This work aims to evaluate the soil physical properties affected by cover crop rotation and soil management in a long-term experiment in southern Brazil. The experiment was established in 1986, with treatments combining six winter treatments and two tillage systems (conventional and no tillage). Bulk density, porosity, aggregate-size class distribution, and organic carbon content of the aggregates were determined at six depths. Bulk density was not affected by tillage systems and winter treatments. The soil disturbance by plowing enhanced the macroporosity, decreased the microporosity, and promoted the formation of smaller aggregate size, in comparison to no tillage. Apart from the soil management, all winter species increased the greater aggregate–size... |

| Results on the applicability of reduced tillage systems are reported to be highly site dependent. To broaden our experience under organic farming, we performed a mid-term experiment comparing RT with conventional tillage (CT: plough) on a loamy clay in Frick (Switzerland). We found, that crop yield was reduced during the conversion period from conventional tillage (CT) to a RT system, but in the second experimental phase, RT exerted higher yields, resulting in a yield increase of 13% in mean. Soil organic matter in the 0 to 10 cm soil layer was 0,37 % higher under RT than under CT, without any difference in the 10 to 20 cm layer. In 2008 and 2009, we established two new experiments on loamy soils, comprising the factors tillage, fertilisation and maize... |

| No Till and Reduced Till are conservation tillage practices with a high potential to restore or improve essential soil functions and mitigate climate change through carbon sequestration and reduced fuel use. While No Till systems are widely used in conventional farming, these techniques are challenging to adapt to organic farming due to weed pressure and frequent nitrogen deficiency in early spring. A potential answer may be Reduced Till, such as shallow inversion ploughing, or non-inversion tillage. The implementation of these practices in European organic farming systems was addressed by an interdisciplinary team of researchers from 11 European countries in a network CORE Organic II project (TILMAN-ORG). Farmer interviews revealed that No Till and... |

| Zonas ripárias são áreas de saturação hídrica, permanente ou temporária, cuja principal função é a proteção dos recursos hídricos de uma microbacia. Essa pesquisa comparou a adequação do uso do solo de dois cenários de planejamento agrícola de uma microbacia: o cenário convencional, representando o método usualmente empregado, que apenas considera as classes de capacidade de uso da terra, e o cenário hidrológico, que inclui a delimitação e avaliação das zonas ripárias. Um estudo de caso foi realizado na Microbacia do Ribeirão São João (3.656 ha), no município de Mineiros do Tietê (São Paulo, Brasil). Mapas de Classe de Capacidade de Uso da Terra e de Adequação do Uso do Solo foram elaborados, utilizando o Sistema de Informação Geográfica (SIG), para a... |

| Bodenlebewesen gelten als die Architekten von Bodenqualität und steuern alle wichtigen Umsetzungsprozesse im Boden. Sie stehen damit in unmittelbarem Zusammenhang zu wichtigen Ökosystemdienstleistungen von Böden wie Kohlenstoffspeicher, Pufferwirkung und Schadstoffbau, Pflanzenertrag und -qualität und Reduktion von Spurengasemissionen. Darüber hinaus gelten Böden auch als wichtige Indikatoren für Bodenqualität, da sie auf Grund ihr er meist schnellen Generationszeiten Änderungen schon sehr frühzeitig anzeigen können. Im Rahmen dieses Projektes soll daher der Einfluss von reduzierter Bodenbearbeitung und Gründünger auf die Bodenqualität untersucht werden an Hand von verschiedenen Langzeitversuchen an unterschiedlichen Standorten in Europa. Bodenqualität... |

| Um einen Überblick über die aktuelle Situation der Bodenbearbeitung auf Ökobetrieben in Deutschland zu erhalten, wurde ein Fragebogen an 3000 Ökobetriebe verschickt. 367 Ackerbauern beantworteten fünf Fragen zur Bodenbearbeitung auf ihren Betieben. 56% der Betriebe geben an nur mit dem Pflug zu arbeiten, 38 % nennen neben dem Pflug mindestens ein weiteres Gerät zur Grundbodenbearbeitung und 6% arbeiten ohne Pflug. 42% der befragten ökobauern bearbeiten den Boden tiefer als 22 cm. 22% der Betriebe arbeiten maximal 15 cm tief. Die Ergebnisse zur Bearbeitungstiefe zeigen, dass sich im Ökolandbau in Deutschland im Vergleich zu einer ähnlichen Umfrage von 1990 eine intensivere Bodenbearbeitung durchgesetzt hat. |

| It has become commonplace to consider ploughing as an agricultural practice that destroys soil fertility. Organic farmers have traditionally used the plough to till their soil and control weeds. However, there is a growing interest in adopting tillage practices without ploughing to preserve long-term soil fertility and in the hope, subsequently, of increasing crop yields. The aim of this paper is to assess if conservation tillage treatments in organic farming did in fact improve long-term soil fertility, wheat rooting and yield in a long term field experiment (2004–2015). We compared the effects of conservation tillage treatments (superficial tillage – ST- with chisel at 15 cm depth and very superficial tillage – VST- at 5–7 cm depth) and conventional... |

| Orchard floor management impacts soil conditions and thus tree performance. This research was initiated to investigate the effects of alternative orchard floor management systems compatible with organic production on soil parameters using the“Pacific Gala” apple cultivar (Malus × domestica Borkh.) on three rootstocks of varying vigor. Alfalfa hay mulch, propane flame burner, and Swiss sandwich system(combination of resident vegetation and tilled strips)were compared from 2001 to 2005. These treatments were applied to tree rows which provided different vegetation-free areas. Contrasting additions of organic matter were evaluated for their effect on soil organic matter (SOM), C content, nitrate and ammonium availability, moisture, and soil food web through... |

| Der Ökologische Landbau wird häufig mit dem zurückhaltenden Einsatz des Wendepfluges in Verbindung gebracht. Erhebungen zeigen, daß der Streich-blechpflug in mehr als 90 % aller Grundbodenbearbeitungsmaßnahmen in der Praxis eingesetzt wird. In der Mehrzahl der Fälle wird bis zu 30 cm Bodentiefe gepflügt. Ziel unseres Forschungsvorhabens ist es, den Einfluß reduzierter Grundboden-bearbeitung auf die Ertragsbildung von Braugerste einschließlich ihrer Begleitflora unter den Bedingungen des Ökologischen Landbau zu untersuchen. |

| In a long-term field trial recently launched (2002-2011), located in Frick (878 mm mean annual precipitation) near Basle, Switzerland, the effect of reduced tillage on soil fertility indicators and crop yield was studied in a heavy soil (45% clay) in a crop rotation under organic farming conditions. We present the results of soil analyses after three cropping years (2002-2005). Soil organic carbon (Corg) increased over that period by 7.4% (+1.5 g Corg kg-1 soil) in the 0-10 cm soil layer in the reduced tillage plots, while it remained constant in the ploughed plots. Soil microbial carbon (Cmic) and dehydrogenase activity (DHA, TTC-reduction) were 28% higher in reduced-tillage plots in this soil layer. Biological soil quality as calculated by Cmic to Corg... |

| Soil fauna diversity, as well as total mite and springtail numbers was correlated with soil type, tillage intensity and fertiliser use as well as crop and grazing history and duration of the current state of the field. 430 samples taken in 2002 on a wide range of organically farmed fields also showed that soil type interacted with crop type and grazing intensity. A higher number of mites and springtails were found in crops that included clover, almost independently of soil type. Higher numbers of mites were found at high grazing intensity compared to low grazing intensity on the same soil type. In 2003, microarthropods were collected in spring, summer and autumn in Southern Jutland, Mid-Jutland and Sealand. In each region both cereal and vegetable fields... |

| Die nachhaltige Erhaltung und Steigerung der Bodenfruchtbarkeit ist für ökologisch wirtschaftende Betriebe von höchster Bedeutung. Im Ökologischen Landbau hängt das Niveau der Bodenfruchtbarkeit – abgesehen von den kaum zu beeinflussenden standörtlichen Gegebenheiten – sehr von der Leistungsfähigkeit der Leguminosen ab. Vor allem durch ihre Fähigkeit, Luftstickstoff zu binden und diesen für ihr eigenes Wachstum sowie für die Folgekulturen verfügbar zu machen, bilden Leguminosen die Grundlage der Bodenfruchtbarkeit im Ökologischen Landbau. In der Konsequenz bedeutet dies, dass Beeinträchtigungen der Leistungsfähigkeit der Leguminosen nicht nur deren eigenen Ertrag sondern auch die Leistungsfähigkeit der gesamten Fruchtfolge am Standort begrenzen. Speziell... |
