The 37 farmers involved in scientific collaboration with the CNRS met scientists with a view to reducing the use of chemical input on the edges of fields

On Thursday 24th May Vincent Bretagnolle and Sabrina Gaba went to meet two of them. On an experimental plot the farmer commented his choices regarding the changing of practices in order to achieve the objectives required by the protocol, i.e. the reduction by half of the use of weedkiller and nitrogenous supplementation over an area established in advance with the farmer.

Both scientists and farmers were thus able to appreciate on the ground the visual differences of this change in practice. The follow-up of the plots during the whole of the agricultural season and in particular the yield measurements will allow the obtaining of scientific results and the sharing of experiences by the farmers taking part.
