| The web platform offers a compilation of various formats and materials dealing with reduced tillage and its challenges regarding weeds. A selection of short movies about mechanical weeding, green manure and tailor-made machinery is listed. Leaflets and publications on reduced tillage can be downloaded. In there, different treatments and machinery are tested and compared to advice farmers on how to conserve soil while keeping weed under control. For Swiss farmers information on the legal framework of direct payment and rules for reduced tillage is available. Furthermore, the platform gives inputs about direct seeding, shallow ploughing and other related issues. Swiss pilot farms involved in trials are briefly portrayed. The outcomes and conclusions... |

| Le sol, composante du Terroir doit être considéré comme une ressource non renouvelable essentielle au fonctionnement des agro‐écosystèmes. Or, les sols viticoles sont particulièrement vulnérables aux dégradations. L’objectif central de ma thèse est donc d’évaluer comment les pratiques viticoles affectent la qualité des sols dans le Languedoc‐Roussillon. Pour ce faire, j’ai d’abord évalué la qualité des sols sur 164 parcelles présentant une grande variabilité de pratiques culturales et réparties sur 9 zones pédologiques très diversifiées. Puis, j’ai évalué la vitesse de changement de la qualité des sols par l’analyse de 23 parcelles d’une zone homogène converties progressivement en viticulture biologique depuis un maximum de 17 ans. Plusieurs indicateurs... |

| A field experiment was conducted under different soil strata in poor agricultural soil condition. Each soil stratum was treated separately with different organic material for soil fertility management. These organic materials are cow dung, sheep dung, goat dung, donkey dung, rice husks, millet husks, Acacia albida, Acacia nilotica, wood ash, house refuses, and combination of all ‘ani-cro-ber’. In the first assessment, soil structure, texture, colour, consistency, bulk density were determined in the field, while in the second assessment N, P, K, Na, Ca, OC, OM and pH were determined under specific laboratory analysis. It is believed that the use of organic materials in soil management is a good way to improve and maintain soil quality and soil fertility... |

| A laboratory mesocosm experiment was performed to study the effects of copper-enriched sewage sludge application on a mesofauna community. For 12 weeks, characteristics and changes in this defined and artificial mesofauna community structure were monitored as well as the dynamics of leaf litter decomposition. The mesofauna community comprised six species of Collembola (Folsomia fimetaria, Isotomurus prasinus, Lepidocyrtus cyaneus, Mesaphorura macrochaeta, Parisotoma notabilis, Protaphorura armata), two species of acari Oribatida (Achipteria coleoptrata, Adoristes sp.), one species of acari Gamasida Hypoaspis aculeifer) and one species of enchytraeid (Enchytraeus crypticus). Three treatments included the addition of 22 g dry weight (DW) sludge spiked with... |

| The effects of ecological vs. conventional farming on several biological, chemical and physical soil properties were investigated at the arable test site Gülzow (Northeast Germany). After ten years of ecological farming increased activities of dehydrogenase, β-glucosidase and alkaline phosphatase in the soil were measured. Low effects on the chemical soil properties like content of Corg, Nt and soil organic matter and no significant effects on physical soil properties like density, porosity and water retention were observed. -- (Sprache des Volltextes: Deutsch) |

| Grasslands are potential carbon sinks to reduce unprecedented increase in atmospheric CO2. Effect of age (1 to 4-yr-old) and management (slurry, grazing multispecies mixture) of a grass phase mixed crop rotation on carbon sequestration and emissions upon cultivation was compared with 17-yr-old grassland and a pea field as reference. Aboveground and root biomass were determined and soils were incubated to study CO2 emissions after soil disturbance. Aboveground biomass was highest in 1-yr-old grassland with slurry application and lowest in 4-yr-old grassland without slurry application. Root biomass was highest in 4-yr-old grassland, but all 1 to 4-yr-old grasslands were in between the pea field (0.81±0.094 g kg-1 soil) and the 17-yr-old grassland (3.17±0.22... |

| In the coming years, agriculture in the Netherlands will be forced to produce more high quality produce with smaller inputs of fertilisers. Organic agriculture should play a leading role and set an example for sustainable soil management. This implies greater nutrient use efficiency and fewer inputs. GPS-controlled precision tillage using the same tracks in the field year after year offers the opportunity to improve soil structure. The tracks become compacted, improving trafficability (Vermeulen & Klooster, 1992). Our hypothesis is that the soil structure of the remaining beds will improve, providing better aeration and rooting for the crop and access to necessary nutrients. This would mean that nutrient use efficiency would improve in GPS-controlled... |

| Depuis 2001, le Groupe de Recherche en Agriculture Biologique étudie différentes méthodes de diagnostic de la fertilité des sols afin de mieux connaître les informations apportées par chacune d’elle et d’étudier la cohérence des résultats obtenus. A cette occasion le GRAB fait intervenir des experts de ces différentes techniques sur le terrain au cours d’une journée ouverte à un large public (producteurs, techniciens, étudiants…). L’action est conduite sur des parcelles de maraîchage de plein champ exploitées en agriculture biologique depuis des durées variables. Quatre sites ont fait l’objet de caractérisations initiales entre 2001 et 2004, puis l’approche est suivie de façon dynamique avec des analyses réalisées tous les 4 ans. Le présent compte-rendu... |

| In mehreren Gefäß- und Feldversuchen sowie Versuchen in Praxisbetrieben (2002/03) und einem langjährigen Feldversuch (seit 1995) ohne Bepflanzung wurde der Einfluss des Mulchens auf den Wasser- und Nährstoffhaushalt sowie auf „Nebeneffekte“ untersucht. In den Feldversuchen erfolgte Herbst- und Frühjahrsausbringung von Kompost, Stroh, Hackschnitzel, Rinde und Gras im Vergleich zur ungemulchten Fläche bei Bepflanzung und ohne gärtnerische Kulturen. In den Gefäßversuchen (mit und ohne Bebauung) wurden die genannten Materialien obenauf gebracht bzw. eingearbeitet und mit der Kontrolle (ungemulcht) verglichen. Im Ergebnis der Versuche ist folgende Quantifizierung für Wasser und Stickstoff möglich: Unabhängig vom Mulchmaterial wird im Mittel von acht Jahren der... |

| Mit dem Ziel, ökologische Bodenbewirtschaftungsverfahren zu erforschen, zu demonstrieren und das erarbeitete Wissen an die Praxis und Beratung weiterzugeben, wurde 1994 in Wörrstadt/Rheinhessen das Projekt Ökologische Bodenbewirtschaftung (PÖB) gestartet. Das auf zehn Jahre angelegte Projekt wird hauptsächlich durch das Land Rheinland-Pfalz finanziert und gemeinsam von der Stiftung Ökologie & Landbau und der Landesanstalt für Pflanzenbau und Pflanzenschutz, Mainz, durchgeführt. Bei dem Projekt werden regelmäßig erfasst: – Textur, Gefüge und Durchwurzelbarkeit des Bodens; – Luft- und Wasserhaushalt; – Stoff-Flüsse im Boden; – biologische Aktivität und biologische Vielfalt im Agrarökosystem. Dabei werden vergleichend die Einflüsse einer intensiven,... |

| Due to the results of organic matter balancing which showed a very high potential of soil organic matter accumulation in organic farming, a research project was started in spring 2005 with the objective to ascertain this hypothesis. Soil sampling was carried out on different organic and adjacent conventional farms in distinct regions of Ger-many. A comparison of the samples regarding Corg showed only minor differences between organic and conventional farms whereas the more sensitive indicators like Cmic and enzyme activities were more affected. However the main influencing factor of all these indicators in this investigation is soil texture. The cultivation system (inten-sive, extensive, stocking, crop rotation, tillage) is more important than the... |

| Spontaneous cover cropping is a common practice in Mediterranean vineyards because it is often seen as less competitive and easier to manage than sown covercrops. However, the services provided by the spontaneous flora highly depend on the species, these latter being influenced by the soil management practices. This study analyzes the specific and functional composition of the vineyard flora as influenced by three soil management strategies. To do so, weed cover was sampled at 5 dates during two years after the settlement of the experiment in a vineyard in the South of France. The three soil management treatments were: a control treatment (C) corresponding to a spontaneous cover regularly mowed, a spontaneous cover with organic amendment application each... |

| Land transformation to adapt fields to mechanization in perennial crop farming is a common practice which includes land levelling, deep ploughing, stone-breakage and clearing, application of fertilizers and amendments. Manipulation of the natural soil profile along its entire depth can severely disturb the naturally existing chemical physical,biological and hydrological equilibrium (Costantini and Barbetti, 2008; Costantini et al., 2013). The most common effects of the land transformation are mixing of soil horizons and soil truncation, which result in reduction of soil depth and available water, organic matter depletion, enrichment of calcium carbonate content in the topsoil,imbalance of some element ratio, and decline in the activity and diversity of... |

| Legume biomass or pulse meal may be considered as alternatives to farmyard manure (FYM) in organic farms with small scale animal husbandry or in stockless organic farms. From 1996 a field trial was established on a poor sandy soil to compare plant based organic fertilisers, FYM and inorganic fertilisers, each applied at 100 kg ha-1 N. Additionally, FYM was tested at a higher rate of 170 kg ha-1 N. Average soil organic carbon content in topsoil (Corg) of the last crop rotation period (2002-05) is compared to that in 1996. Corg remained at the same level of 0.78 % only with FYM, while plant based and inorganic fertiliser decreased carbon contents to 0.74 and 0.72 % Corg, respectively. The higher FYM rate increased Corg up to 0.84 %. Based on these results,... |
