| Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in... |

| A multi-year trial was conducted to compare soil management strategies (tillage and fertilization) with regard to their effect on crop performance and soil quality. Two soil management systems were assessed. Farm compost application was combined with reduced non-inversion tillage, whereas animal manure was incorporated by conventional tillage with a moldboard plough. With regard to soil quality, a reduced tillage practice in combination with compost application seemed to be favorable for soil quality of the surface layer in the short term. With regard to crop productivity, an effect of soil management strategy is less clear and dependent on a seasonal variation of growth circumstances. |

| As part of the TILMAN-ORG CORE ORGANIC II project, data on the use of reduced tillage in organic farming systems from a range of field trials and the published literature was compiled. A meta-analysis was conducted to determine the impacts of reduced tillage on crop yields, weed pressure and soil organic C stocks. This paper highlights some of the key findings from this study. |
