You should be able to providing ammonium nitrate and water is the only ingredients. Ammonium nitrate is a powerful oxidizer meaning it will burn things on contact like your plants,there roots and your flesh. I've never dealt with cold packs so I have no idea what the final concentration is after they are used. Diluting it significantly like 20 to 1 and testing a small amount on an expendable plant would be advisable. Pure ammonium nitrate only supplies nitrogen. Your plants also need potassium and phosphorus and the ratios vary from plant to plant. If you want to do some weird science try diluting it then mixing in a few handfuls of wood ash for the potassium,pee in it a few times for the phosphorus then test some on your plants. I use nitrogen based fertilizers mixed with ash from my fire place and pee on my outdoor plants all the time when no one is looking and they are doing great. My neighbors think I have a green thumb but I'm allways tempted to tell them, No. I Have a green p*&@#r. Good luck.
The nitrate ion imparts no color to a solution.
Yellow-Green
Copper (II) Nitrate burns in a Green flame
The flame color would be green.
set on 3.25
You would want to use spreader setting 3.25
Overseeding -- 7 1/2 New Lawn/ Bare spot -- 18 but it would be best to go over the lawn twice at setting 7 1/2 in perpendicular directions.
setting @6

barium nitrate is used for flairs, explosives and is also used in the vaccum tube industry!
