I am sending the pdf of the article "Mechanical and biological chiseling impacts on soil organic C stocks, root growth, and crop yield in a long-term no-till system" and the slide show. This article clearly shows that the no-tillage system well done (based on the principles) is not necessary to chisel the soil even if compaction is diagnosed. We have shown that the use of cover crops such as forage turnip is an excellent tool to relieve the symptoms of compaction, increase C in the soil and increase root growth and grain production. Also I am sending the slide show of this article. You can share both with CA-CoP.
