Ever use urea
I just applied some urea to my fields. The week before, I overseeded them with a pasture mix. Any idea how long it should take to see some lil green things?? Does urea really help make the stuff grow better???

Guess I'll stick my neck out about something most people know more about than I do. Maybe I'll learn something.
I think urea is a nitrogen source. I remember that higher priced fertilizers often were advertised as 'urea based.' I think urea breaks down into usable nitrogen more slowly than ammonia sources, which is often desirable.
Whether urea on its own is good for over-seeding or not depends on soil conditions and the particular crop. Sources of other elements in addition to nitrogen are desirable for balanced growth. Excessive nitrogen promotes excess top-growth and may produce inadequate root development. I'm guessing that grass seedlings can use a lot of nitrogen, so straight urea might be pretty good.

I want to personally thank you for putting the urea on your fields and not in your tires as ballast. When I saw the heading I thought.. Here we go again. Tom is right. Urea is a complex form of nitrogen. When you are feeling bad on of the test the doctors will do is called BUN. It stands for blood urea nitrogen, a byproduct of protein metabolization. A low number means your kidneys are working well.

Ever use urea
Notes from Penn State Univ:
"A dry material in granularly or prilled form, urea-N rapidly hydrolyzes to NH4+. Used for direct application,in mixed fertilizers,and in liquid nitrogen. N at application is present as urea-N. Within 1 day after application, about 66% of urea-N is hydrolyzed to ammonia-N; all within 1 week.
When not incorporated, significant N loss by volatilization can occur until approximately 0.5 inch of rain has fallen. Not recommended for starter use.
Broadcast (incorporated) or sidedress."
So basically my understanding of urea is: organic compound
that is the principal end product of nitrogen metabolism in most mammals ... -- does this mean we're talking about crystallized urine ????
Anyway, my guess is that urea is too "hot" for most grass fertilizing applications. Commercial grass fertilizers even the cheap junk will dissolve over a period of time to prevent burning the grass. I've burned enough dead spots in my fields by excess application (i.e. spills) to understand that grass can't take a heavy infusion of nitrogen.

Crystallized urine is uncommon in humans but common in male house cats. In small felines the tolerance stack consisting of tiny urinary openings, high Ph, low urine volume and high protein diet can combine to plug them up and kill them.
If your question is “Do I have nitrogen compounds in my blood and urine?” then the answer is yes, but a healthy set of kidneys will hold the BUN, creatinine and uric acid levels to very low numbers, and if we drink lots of water these materials will not precipitate into crystalline form in our bladders.

Tag, I'm it.
Even my wife sez i should relax more. But don't feed your cats too much protein anyway. Mark

I think it is a case of what is good for the goose is not necessarily good for the gander.
Urea application is common for corn where high nitrogen levels are needed. I have not heard about urea application on grass. In general, most grasses will burn with the application of urea (established grass). The urea will do 2 things add nitrogen good and make the soil more basic, good or bad depending on the soils original condition.
Did you get the soil tested before you added the urea?
Most commercial fertilizers contain some urea but are slower release than straight urea or liquid urea. Even with slower release fertilizer you can burn grass. Even animal base urea will burn the grass if applied to heavily. (Less beer and use different trees)

Glad you caught that one. I still had to explain it to my wife.
We all gain trivial knowledge from the discussin even when we miss the point.
For instance I now know why the male cat urine smells so bad, when the neighbours cats pee on the welcome mat and all I need to get rid of them is to feed them a high protein diet. Does force feeding soy products work? Or am I missing the point also?
