I want to show you how soil disturbance through tillage impacts soil function. Here are two
-
soils. This soil has been disturbed by conventional tillage. This soil has not been tilled for
-
40 years. It’s virtually undisturbed. Watch what happens when I simulate rainfall on these
-
two soils.

-
The undisturbed soil allows every precious inch to infiltrate. This is good for your
-
production and for the environment. The disturbed soil does not allow the water to infiltrate.
-
Most of the water is going to runoff, and place your soil into drought mode, and put
-
your nutrients into the nearest lake.
-
When it comes to building healthy productive soils, remember, do not disturb.
