This is a good thread.
If I may add, how is a coated synthetic fert going to last all winter in snowbound areas? We frequently get some freeze/thaws in the winter. If that fert is underneath 6" of snow, it is at or slightly above 32 degrees in there. Probably a bit warmer on those freak warm winter days of 40+. Nitrogen has to be leaching downward a lot of that time. And if the plants aren't using it, bingo, wasted. Any thoughts?
This is not to mention the melt off we get in March, the N waste during that time has to be tremendous.
