Urea
(46-0-0) usually has the lowest cost per pound of nitrogen
compared to other single-element nitrogen fertilizers. however,
urea undergoes unique chemical transformations when field applied
and severe losses in efficiency may result if special management
practices are not followed. The purpose of this fact sheet is to
briefly describe urea transformations and to suggest how urea-N
may be conserved with proper management in the
field.
Fertilizer urea can be purchased as prills or as a granulated
material. in the past, it was usually produced by dropping liquid
urea from a " prilling tower" while drying the product. the
prills formed a smaller and softer substance than other materials
commonly used in fertilizer blends. Today, though, considerable
urea is manufactured as granules. Granules are larger, harder,
and more resistant to moisture. As a result, granulated urea has
become a more suitable material for fertilizer
blends.
