We often talk about the value of soil porosity and soil biology, and we talk about macropores and earthworms, but a video taken by Dave Robison of Cisco Seeds really did a nice job of visually portraying a good soil profile built upon high earthworm populations (and numerous earthworm channels), the benefits of cover crops, good tile drainage and more.

In this video, you can see smoke from a diesel engine that’s pumped into pressurized tile emerging from the macropores of a corn field. It’s a pretty neat site to see the smoke rising up from the soil. You can see more videos at www.plantcovercrops.com.

Frank Gibbs, NRCS soils specialist, presented this experiment in Williams County, Ohio.
