I put out pelleted fertilizer (11-54-0) yesterday. Probably won't dissolve for months. The liquid stuff would have been fantastic. I should have asked if my Co-op had that. Shouldn't be a difference between that and the stuff marketed towards fish. You could check the ingredients to find out how they're getting those N-P-K numbers for good measure.

What's the cost of the liquid stuff? Since the numbers are a percent by weight, I presume 10 lbs of the liquid 10-34-0 has the same quantity of N-P-K as 10 lbs of solid 10-34-0. For comparison sake, the solid stuff should be about 10 lbs/gal.
