I am doing every acre, price is same as Tiger 90 which I have been using for 15 years or so. I am paying them to custom apply it but I have a lot going on this fall and am not sure I have time to handle all that Tiger 90 myself. I am not counting on anything out of the compost part of it because right now I can't be sure if it actually does anything except add topsoil like dookiller noted.
To me doing a big shot at once gives me peace of mind that I don't have to worry about S for a few years. Big crops needs lots of S and we have been taking big crops off for awhile now. To me bulk applying nutrients at the cheapest cost per unit is better than spoon feeding crops every year. I own all my land so these decisions become a longer term investment too.
AN ERROR DOESN'T BECOME A MISTAKE UNTIL YOU REFUSE TO CORRECT IT
