Ivan Dozier, state conservationist for the Illinois Natural Resources Conservation Service, delves into the basics of organic matter, including short-term versus long-term organic buildup. He explains the benefits of the mulch effect, which include preventing erosion, suppressing weeds, improving tilth and helping soil maintain moisture. Growers can see the benefits of the mulch effect in as little as a year, which is why many farmers are adopting conservation practices on their acres.
