Good article here on fertilizing. Also gives ideas for other ways to fertilize outside of buying it in the bag. I recall prior posts about fertilizing a pond to initiate a bloom had higher numbers recommended on the nitrogen, Phosphorous compared to the 8-8-2 recommended in this article.
Fish feed as a fertilizer is discussed (catfish feed in particular)
info on fertilizer I have some left over milorganite (best known organic fertilizer, 6-2-0) to use up and may toss that in my pond although my water temps are probably too low for a bloom yet this fall. I assume milorganite is commonly available all over the US, but in case you are not familiar with it,it is made in WI from 'byproducts of wastewater' (poo) It is nice to use on just about anything as you can't very easily 'burn' anything.
Milorganite My struggle is keeping the phosphates out of the pond.
