US 52% No-Till
Field-level data, collected through the Agricultural Resource Management Survey, show that farmers often rotate no-till with other tillage systems.
Farmers growing wheat (in 2009), corn (in 2010), and soybeans (in 2012) were asked about no-till use in the survey year and the 3 previous years.
No-till was used continuously over the 4-year period on 21 percent of surveyed acres. On almost half of the cropland surveyed, farmers did not use no-till.
Some of the benefit of using no-till, including higher organic matter and greater carbon sequestration, is realized only if no-till is applied continuously over a number of years.
Nonetheless, because tilling the soil can help control weeds and pests, some farmers rotate tillage practices much like they rotate crops."
That's higher than I would expect, especially with all the tillage you read about and see. If this is true, it is a good trend for soil conservation. With the Marestail problem, I know a few who have went to some tillage just to try and control it.
I can see where today's economics help push no-till, because it's a potentially less expensive way to farm. Less trips means less inputs into growing a crop.
Do think this number is fairly accurate for your area?
