Urea
Typical nuetriants: 46% nitrogen, other sub micro nuets


A white crystalline solid containing 46% nitrogen, is widely used in the agricultural industry as an animal feed additive and fertilizer.
If properly applied, urea and fertilizers containing urea are excellent sources of nitrogen for crop production.

After application to the soil, urea undergoes chemical changes and ammonium (NH4 +) ions form. Soil moisture determines how rapidly this conversion takes place.

When a urea particle dissolves, the area around it becomes a zone of high pH and ammonia concentration. This zone can be quite toxic for a few hours. Seed and seedling roots within this zone can be killed by the free ammonia that has formed. Fortunately, this toxic zone becomes neutralized in most soils as the ammonia converts to ammonium. Usually it's just a few days before plants can effectively use the nitrogen.


posted too clear up the Urea myth

Tamzi

Tamzi.... Good info, everything has a place and a use. Even urine (aka urea), though most commerical Urea ferts are made from ammonia & carbon dioxide, in a chemical reactive process. So, Urea, regardless of the source - is still all Organic.
.
I've used this stuff to jump start a huge compost pile before. It works great, smells heavily of ammonia for a day, but then fades to nothing over the course of two or three days.

At a Farmer's Co-Op you can get it cheap. I bought a busted 25 # bag for $ 6

im not a pro like ohso but i saw somewhere that the N_P_K numbers ae just the % of that specific nute solution. this almost makes me more confused tho, im wondering if that means the rest of the solution is water? 70%
