Turf Fert in Aquarium - Bad Idea?

Ok so this is probably an awful idea, but I figured I'd ask (and I can't find any info on the web, so...here goes).

I work for a plant science professor on campus and today we were using a new fertilizer when I got my terrible idea. So this fertilizer isn't what I would think if I were to think of fertilizer - it was this bag of yellow and white crystal like pellet things. Apparently it's a slow-release formula or something (I'm not too sure - plant science isn't my forte), but here's what the info on the bag says:

Harrell's Professional Fertilizer: Turf Specialty, Professional Turf Fertilizer
22-3-11
50% SCU, MOP, 3% Fe, 240 SGN

Guaranteed Analysis:
*Nitrogen - 22%
1.15% Ammonia Nitrogen
20.85% Urea Nitrogen
Available Phosphate (P2O6) - 3%
Soluble Potash (K2O) - 11%
Sulfur - 33%
Iron - 3%

*9.9% slowly available nitrogen
Derived from:
Polymer Coated Sulfur Coated Urea, Urea, Ammonia Phosphate, Muriate of Potash, and Iron Socrate


So yea...my question basically, has anyone tried using just regular old fertilizer in an aquarium. Is this just an awful idea?

I figure I would only mix in about 1g of the stuff in with the lowest level of my substrate (which will be Schultz - which is inert, which is why I even thought of this...figured that the ferts would leach into substrate and be absorbed by plants and substrate).

So yea...lol. I expect this will be met with a resounding NOOOO but I figured I'd at least ask :grinyes:

lol. that might be an issue.

i wasn't putting much stock in this idea, just wanted to know how plausible it was erv:

yea I noticed that when I compared it to my bottle of flourish.

and there's a whole bunch missing too...

kinda weird, you'd think all plants need about the same type of thing
