There is probably no hotter topic in the farm equipment industry today than vertical tillage.
Since the 1990’s, when soil density effects were studied and the term “vertical tillage” was coined, there has been an ongoing erosion of what the term really means. It has come to the point that there are numerous machines on the market that are sold as vertical tillage that do not meet the criteria of what vertical tillage is all about.
To address this issue, one needs to understand that vertical tillage means that the ground engaging components of a given tool enter the soil in a vertical rather than horizontal fashion. Conventional “horizontal” tillage implements, such as disk harrows and field cultivators, create horizontal compaction or stratification layers in the soil. These density changes inhibit root growth, impacting crop stand ability and yields.
