| Agricultural practices, and mainly soil tillage, highly contribute to the emissions of greenhouse gases such as CO2 and N2O. Reducing the tillage improves the quality of the soil and may help mitigating the greenhouse emissions. In Europe, approximately 25 % of the arable land is managed under reduced tillage practices, including both notill and reduced tillage. However, they have been developed mainly in herbicidemanaged systems. The potential increase in weed infestation caused by the lack of soil inversion may threaten crop yields, and is one of the major drawbacks for the adoption of reduced tillage among organic farmers. We report the results from a field experiment comparing the reduced tillage with respect to the conventional tillage in the... |

| This work aims to evaluate the effect of crop type and density on insects’ community in the Mediterranean re-gion. In winter of 2004, four 35m x 10m blocks (replicates) were delimited and 24 equidistant 2m x 3m plots were marked. Seven crop types (barley, vetch, turnip, barley-vetch, barley-turnip, vetch-turnip and barley-vetch-turnip) at three densities were randomly established within each block. Fifteen crop shoots per plot were randomly collected in May to evaluate insect’s abundance and diversity. Our results suggest that inter-crop has a positive effect on abundance of most exam-ined groups of insects and diversity, specifically when vetch is incorporated in the mixture. Changes in abun-dance of aphids, trips and ants are also discussed connected... |
