Use of woody residues to restore soil fertility, control weeds and develop sustainable field crop systems

Based on a trial carried out at Agroscope Changins, the aim of this project is to quantify the effects of 1) sawmill residues (Abies alba bark) and, 2) woody compost residues (screenings). After spreading 300 m3.ha-1, both types of residue are applied as mulch or incorporated. The following parameters are then monitored for the duration of the project:

1. nutrients (soil/plant) during a rapeseed and then wheat crop,
2. carbon pools, soil physical properties and the link with earthworm activity,
3. weed development.
