>green; fresh stuff. Clippings, weeds, kitchen scraps, manure>brown; old/dead stuff. Cardboard, paper, dead leaves, sawdust, straw>blue; water. Keep it moist. Not soaking wet. If it's not raining, add a bucket of water. Too green and it will start smoking or turn to sludge.
Urea is an additive. Normally you age it before putting it on stuff because it's pretty rich and can kill some plants. Just piss directly at the base of lemon trees because they can handle it for some reason. Normally you keep it away from produce, but whatever, it's your own garden.
Sawdust is a brown. Mix it with grass cuttings from your mower and kitchen scraps. 50/50 ratio or thereabouts is ideal.

basically just build a bigger cum jar out of a sealable 40 gallon drum, add some water, add your spoiled material and stir and seal. Add any other random organic garbage at your convenience and stir. Add water if your brew is too solid.
Get some good anaerobic activity going. Give it at least a couple of months for the initial deposit to develop some character before use.
I'd dilute the resulting brew and use it on anything away from the house and not intended for human consumption.
