I am trying to animate a ball rolling through a desert scene, leaving a trail behind it. The intention is for the ball to move along the surface of the plane rising and falling with its ridges.

In order to accomplish this I have attempted to use dynamic paint along with the shrink-wrap constraint.

When I attempt to make the ball follow a curve, dynamic paint does not appear to have any effect at all. When I add key frames, a trail is left that adheres to these but does not follow the shrink-wrapped path.

As a workaround is it possible to keyframe the shrink-wrap path?

Am I perhaps approaching this from the wrong direction? Please forgive my lack of blender prowess.
