Vegetation as snow fencing

This morning, on my daily commute, I noticed that just a few sprigs of tall grass can be sufficient to keep snow from drifting back over the roadways in current conditions. Yet I still had to drive through mile after mile of drifting and blowing slow where gigantic recently tilled corn, soybean, and wheat fields meet the highway with only a narrow strip of mown grass between. The drifting snow creates a hazard for, and must be cleared at great expense by, my community. I see this as yet another design failure of big ag. I wanted to share this observation as it hadn't occured to me until this morning that the push for larger fields with fewer breaks has burdoned cold weather communities in this way. Also something for designers in wintery areas to keep in mind.
