Frank Gibbs, a consulting soil scientist retired from NRCS talked about the positive effects of cover crops and no-till on soil quality at the National No-till conference. In the first video, Frank discusses the positive effects on rooting and shows you his smoke machine. He also shared this video to demonstrate, with is smoke machine, how water and air move through the soil. The smoke rolling out of the worm holes and root channels is very compelling. Some of us would have like to see the smoke demonstration on conventionally till soils as well.
When he demonstrated the smoke on tilled ground, little to no smoke came through the soil, Dave!
