Vertical tillage is beneficial for cutting and sizing residue while mixing it with soil to convert it into organic matter for healthier soils and a more uniform and receptive seeding environment. Vertical tillage tools will run in wet soil and can help warm up cold soil for quicker, more uniform seed emergence.
Does vertical tillage increase yield?
Yield Impact by Tillage Type
Many studies done over the last 15 years have determined that yield outcomes of vertical tillage and conventional tillage are very similar. However, when comparing yield levels of vertical tillage to no-till, vertical tillage systems are typically an improvement.
Is vertical tillage a fad?
This is why vertical tillage, more specifically "vertical finish" shouldn't be considered a fad. It's almost another class of tillage. Keep the ground structure intact, but still be able to create an ideal environment around the seed to promote even emergence.
