Could Cover Crops Have Prevented Deadly Illinois Dust Storm?
At least seven people were killed in a massive crash involving over 70 cars along a 2-mile stretch on Interstate 55 in central Illinois on May 1. The crash was caused by excessive winds blowing dirt from recently tilled farm fields, which lead to zero visibility, according to Illinois State Police.
Holtwood, PA., no-till advocate Steve Groff took to Twitter to express his thoughts on the tragedy.
āIāve been told by folks who were in the area that fields that were cover cropped and no-tilled had no dust blowing,ā Groff says. āTillage was the culprit, plain and simple. If this is not actively addressed, farmers may become liable.ā
Fellow No-Till Innovator and retired ag engineer from Ohio State University, Randall Reeder agrees that tillage was the catalyst, but he encourages people not to point fingers at farmers in the area.
āWe need to keep in mind that these farmers are tilling the same way their ancestors did long before they dreamed up an interstate highway system,ā Reeder says. āWith that in mind, itās clear that no-till and cover crops wouldāve prevented the dust. Youāre just not going to get any substantial dust planting in a no-tilled field.”
āSome people would refer to this as the perfect storm, although I donāt think thereās anything perfect about it. Itās late spring. People are out tilling the ground. Thereās a dry surface area and suddenly extreme winds blow in the wrong direction. This situation doesnāt occur very often, probably no more than once every 15-20 years in a major corn producing state.ā
While the Illinois dust storm might evoke memories of the Dust Bowl during the 1930s, Reeder says the two incidents are very different.
āKeep in mind the Dust Bowl was a result of years of terrible drought,ā he says. āThis situation in the Corn Belt is not like that. Itās just the result of a short-term dry spell on tilled ground with high winds.ā
Retired USDA soil scientist Don Reicosky says an incident like this should never happen in the Corn Belt, a region containing what he calls āthe best soils in the world!”
āWe know that Conservation Agriculture is a much better way to farm profitably with reduced input costs and virtually no environmental costs repairing a degraded ecosystem,ā Reicosky says. āWhile we are seeing progress with slow acceptance by innovators and progressive farmers, we must find some way to market Conservation Agriculture so that it is accepted by all farmers, consumers, environmentalists and policy folks. Our food security depends on conservation principles and practices to avoid these kinds of environmental catastrophes.ā
