Blue stuff is 24-8-16 and label says 1 tablespoon per gallon. So spilling a bucket is not a lot of fertilizer. You can use it in your lawn, but put no more than 0.25 # N/M. In other words putting 1 pound of this over 1000 sq feet is okay.
If you can get it free go for it. Mix 2# with 2G of water for 2k. Better if you use 4G of water to prevent leaf tip burn.
