SOIL HEALTH IN PRACTICE - REAL SOLUTIONS FROM REAL FARMERS

While no one wants to take prevent plant, this cloud can have
a silver lining. Many farmers have been stuck in a corn/soy-
bean rotation (or lack of rotation) for many years so this can
be an opportunity to add diversity to the system. A diverse
multi-species cover crop mix planted into prevent plant acres
can greatly stimulate soil life and soil biology, while suppress-
ing weeds, interrupting disease cycles, and even produce and Currently two of his favorite legumes to include in mix-

Lebanon, IN farmer Dave Chance was not exempt from
prevent plant this spring, and had to drill covers on 600
acres of his 2,200 acre corn and soybean farm. Chance is
passionate about the health of his soil and saw this setback
as a golden opportunity to add the diversity from the cover
