Vertical tillage

A tillage method emerged in North America in the 1970s and 1980s and designed to size, slice, and chop after-harvest crop residue while only penetrating a few inches of soil. The soil is worked vertically to avoid the addition of horizontal layers or density changes. The residue is typically left on the surface to decompose. The area under vertical tillage can be specified as a percentage.
