How deep do you paraplow and are you planting on the slot? 

That side dressing has to take some ponies.

Are you planning on slotting every year and Deep side dress every year?

We are building 16 to 20 inch deep zones. One set one fall and one the next.  Then do not plan on doing again for hopfuly 6 to 8 years.  Just strip till back on the old zones.  Our roots are noticably bigger than conventional tillage also.
