| Organic farmers are encouraged to adopt conservation tillage to preserve soil quality and fertility and prevent erosion. However, many studies in different soil and climate conditions have demonstrated that the compaction of the untilled layer is higher in conservation tillage than in conventional tillage. As earthworm activity may help alleviate soil compaction in organic farming, the impact on the soil structure and earthworm population and activity was studied for 4 different tillage managements (1) mouldboard ploughing (MP), (2) shallow ploughing (SP), (3) reduced tillage (RT) and (4) no-tillage (NT), in 3 french areas. The first results are: (1) MP soil structure is better than SP, RT and NT, (2) water infiltration is higher at soil surface in SP, RT... |

| Afin de suivre l’état physique d’un sol, différents outils d’observation au champ existent. En Europe du Nord, on retrouve le test VESS (Visual Evaluation of Soil Structure) issu du test Peerlkamp. Ce test VESS permet d’apprécier la qualité de la structure des sols au niveau des premiers horizons. Il est basé sur un système de notation de 1 (très bonne qualité de structure du sol) à 5 (mauvaise qualité de structure du sol). En pratique, sa réalisation sur le terrain dure 5 à 15 minutes. Il permet d’avoir diverses informations sur les agrégats du sol (taille, forme, force, couleur) et les éléments biologiques (présence de racines). On peut aussi apprécier les éventuelles porosités. En Nouvelle-Zélande, le test VSA (Visual Soil Assessment) est pratiqué.... |

| Conservation tillage in conventional agriculture tends to make the cropping systems more dependent on herbicides. Organic farming principles could solve this problem. However, direct drilling under a cover crop in organic farming remains difficult. We need innovative techniques, such as knife roller and adapted cover crops. Reduced tillage is possible if weeds are well controlled with mechanical tools, such as hoeing for spring crops, i.e. maize in 2005 and soybean in 2006 (site A). If though weed infestation increases during one year, it will be difficult to control it in subsequent crops in case of reduced tillage. |

| To understand how earthworms could improve soil porosity in no-tillage organic farming systems, the aim of our study was to compare the effect of different tillage systems on earthworm populations, from conventional (traditional mouldboard ploughing, MP and shallow mouldboard ploughing, SMP) to conservation tillage (reduced tillage, RT, direct drilling or very superficial tillage, NT) in three organic arable systems in France (sites A–C). In a second stage, the effect of earthworm activity on soil porosity under the four tillage systems was assessed at sites A and B. Earthworm abundance, biomass and diversity were measured over a 2–3-year period at the 3 sites. During the same period, soil structure (soil profile description and soil bulk density) and open... |
