I have really poor rocky soil so I'd like to eventually move to the no till method and buckwheat as a cover crop to start building up my soil. I have a powerline that I am wanting to plant this fall and trying to figure out the best tool for the job to bust it up to plant. I currently have a box blade that I used for making a food plot last year but it moved more dirt than I wanted. Would a disc harrow be able to work rocky ground that hasn't been worked in a long time or should I use the box blade? I don't want to spend the money to buy the disc if it won't work much better than the box blade.
