I am a no till farmer. I want corn stalks to be mixed in with upper soil, yet I don't want to loose soil saving of no till, due to water wash off. I have lots of hills, so I want the soil stable. Will vertical tillage give me what I want and not disturb the soil to the point I have to worry about run off.
Re: vertical tillage
If you desire a lot of mixing, it requires loosening enough soil that erosion will be a factor with a heavy rain. If you can work with the results from a vertical cut implement that primarily sizes the residue and follow (either separately or in combination with the vertical cut implement) with some type of rolling basket/harrow which is run shallow and mixes the small amount of loose soil with the residue, erosion will not be a big concern. Obviously running across rather than up-down hills generally results in less erosion.
