In attached file I am sending an article published at Soil and Tillage Research about: Mechanical and biological chiseling impacts on soil organic C stocks, root growth, and crop yield in a long-term no-till system. The results (see ppt) show clearly that when we practice no-till system based on its 03 basic principles, we can control and overcome compaction effects with the use of plants with a robust and deep root system.
