1kg of urea should cost you no more than £1/$1.50 at an ordinary garden centre. It is sold as lawn food, often with "soluble",
"fast-acting" or something similar on the packet, not "slow release" or "controlled release". It's NPK rating will
be 46-0-0 and it should also say "ureic nitrogen, 46%" somewhere on the packet, or words to that effect.
It WILL be there somehwere, just check the ingredients of the fertilisers that they have.

I get my urea (~90%) from a 'Produce wholesaler', it was AU$ .8 for a kilo. This guy supplies all the farmers in the region; he's a bit
shady, so we have this understanding.

What about isolation from urine? Why to waste it?

I would rather pay the price for the urea than gathering, storing and processing many liters of urine. Some cold packs contain urea while others
contain ammonium nitrate. Take a look at the content listing on the back.
