Ut, oh. Bloodmeal (or more poopy) is your friend.
Pat hit it on the head ... you have a recipe for N shortage going there. Two thoughts come to mind.
1) the bloodmeal or additional source of N is a "quick fix" for this year
2) the N consumed by the sawdust this year will be (mostly) available next year at which point your soil structure will also have been given a boost.
