until the wee hours of the night. That was some of the best
times as a junior high and high schooler, being able to help
out my dad and run the ripper. I didn’t know that there was

were growing. I thought you had to have the seedbed fully
prepared or else it would seal up over the top and the corn
wouldn’t be able to come through the crusted-over soil. I
thought tillage was the answer.

of years into it, we’re having a hard time keeping residue on
the soil, and we have had to be more aggressive with carbon
inputs from cover crops to feed the system.
It wasn’t until we got into cover crops that our no-till sys-
tems really started to work. I encourage farmers to adopt
