You can buy the corigated cardboard with just one side smooth and the other just corigation. Then spray it with glue and sprinkle on "dirt ground cover".
Or cover the area with joint compound and make the furrows with a mastic tool. The advantage of this method is you can make wavy lines to follow the sight like tractors do. When dry, spray with glue and add the dirt ground cover.
I believe one of the vendors like walthers sells "plowed fields" that are just cardboard as described above.
