I’m down here investigating this incident right now. So far there is no proof that any farmer was in the field with a tractor or combine kicking the dust up. However there is proof that some of these farms have removed the fence rows and hedge rows that are supposed to brake up the wind. These measures were implemented after the Great Dust Bowl back in the 30’s. Some of the farmers want that land where the fence and hedge rows are for planting more crops. I have a feeling that will be addressed soon. There’s a great documentary on this subject called Kiss the Ground.
Thanks for the information. I live in New Mexico, and we see hard winds in the spring. Just the way of life here. I've seen those types of windbreaks all over the west. One thing I've noticed is they tend to work in lighter winds, but not in the winds that hit hard and fast and lift the top layers of soil up. There's little protection from that.
