Urea is *6% nitrogen, so its analysis is *****0. This actually has
carbon in it, so in a sense, you could call it an organic nitrogen.
Not that it\'s approved for organic use, but it does have carbons
in with the nitrogen so carbon is part of the molecule of
urea.
Urea is a high analysis dry nitrogen. It has a tendency to
dehydrate the soil, so it has to be used where there is adequate
water. In the right place it can be very
useful. One
of the uses it\'s really good for is in corn when the equipment
requires a dry application of nitrogen. Urea
is a dry granular, so it can spread with a fertilizer spreader just
fine. It mixes pretty well with phosphorus and potassium products.
You do have to be careful mixing it into limestone. Pelletized
limestone and urea would not stay in very well together.
