I have a question about using the earthway with a plate for side dressing . i have the attachment for fertalizer but it is gravity fed so keeping a consistant speed is very important and if you get hung up on something it leaves a pile so i am very interested in the method and plate you use and do you go down both sides of the row? how far out ? Maybe i wont have to do a bunch of testing do you know how much it applys on a 100 ft row with the pea plate ??? Thanks for any help
