Slake and Infiltration - Test by Ray for ENHS 766 Class

This is a video I took of my buddy, Ray Archuleta doing a slake test and then a rainfall simulation/infiltration test.

He is showing the difference two soils, same type but different soil structure. The one has been tilled (i.e., disturbed) while the other has been no-tilled and has had cover crops growing every winter. So the soil types are the same but their ecological functionality in terms of cohesion and infiltration capacity are vastly different.
