Southeast WI | I will have to read the article closer to see what their angle is. However Frank Gibbs from NRCS has been demonstrating macropores in tile drainage ground for a long time. I thought this was a decade ago we did this - wrong, it was back in 2006. This was done on a clients farm where we had a long term NT vs T replicated trial set up. I posted data of that long term trial here several years ago. We ran it for 20 years. Now that farm is almost 100% notill. It was an awareness issue using smoke. That work has led to some new regs for manure applications when manure DM is very low as that type of manure leads to quick entry into tile under some conditions. This is an awareness that was needed.
The link I found in a 10 second Google search. I was surprised it was that long ago. Soil health and water quality issues aren't a new concern.
