Tillage is an old practice but this does not mean that it is no longer being improved. Modern tillage has features that can cope with shallow or deep working depth, a toolbar that practically guarantees a straw-free surface and a control panel in the tractor cab that increases the capacity. Automatic and GPS-assisted on-land tillage and specialist implements for shallow tillage are also available on the market nowadays.
A common problem in tillage is the creation of a hard pan (a compacted layer below tillage depth). Tillage depth should therefore be varied between years. If large amounts of straw are present there is a risk of a straw layer being created at the furrow base, a problem that can be rectified by a prior pass with a Carrier.
