ENGAGED: System design of direct seedings under permanent cover crop without glyphosate

Direct seeding under permanent cover crop (SDCV) corresponds to sow a crop in a multiyear vegetal cover crop(often clover) without soil perturbation. It is an emblematic technique of Conservation Agriculture whose agronomicand environmental interests are multiple because of the special attention paid to soils. However, the issue of weedcontrol and permanent cover crop control is central to SDCV culture systems. The use of non-selective herbicide suchas glyphosate is the most common technical lever for weed and cover crop management.
