Urea properly used is an excellent fertilizer which has a wide range of physical and chemical properties useful in fertilizer production. Agronomic problems exist but they can be overcome by using well known techniques. There are some who because of agronomic limitations will not accept urea. There is little question that economics, safety and storability favor urea. Usually the farmer who buys a blend is only interested in top agronomic performance at lowest cost and only specifies a given ratio without regard to ingredients. This allows blenders to choose the most economical nitrogen source and an increasing number are choosing urea.
Most problems with urea have practical solutions. A major objective now is to convince the user that the problems can be overcome and to teach him how to overcome them.
