Aims:
To focus on the impact of trafficking by heavy vehicles on crop production and soil condition, as well as monitoring how quickly LRZ soils will "self-repair" if heavy trafficking is stopped. Issues of implementing CTF and managing permanent wheel tracks are being addressed in other components of the project.
