In South America, the no-till revolution had cover crops front and center. Whereas, in the United States the no-till revolution started out with cover crops. If you look at the old extension bulletins from the 70's, cover crops were recommended. But pretty quickly, the no-till revolution of the United States really became about leaving dead crop residue on the surface.
When the American scientists and farmers went down and looked at the no-till being practiced in Brazil, Paraguay and Argentina they saw that cover crops were really important. It was a key part of how they did their no-till, and they saw lots of brassica cover crops.
With that inspiration, Dr. Ray Weil's Brassica Research Team was born.
