Main Lessons Drawn from the Simulation Study,on of the soil and climate context in a broad range of French conditions. By doing so, it will be possible to optimize the associated management technique and identify situations in which their use may have negative consequences on the next crop and, potentially, on groundwater recharge.

Study Context and Methodology,ll as the cropping system. The reduction lies in the range of 20–90 % compared to bare soil. This broad range of efficacy needs to be analysed on the basis of factors determining water drainage and nitrate leaching, as well as the other multiple functions of cover crops.

Book 2017lso analyzes both the negative impacts they can have and the ecosystem services they can provide. The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the dra
