WHAT IS THE BEST NITROGEN FERTILIZER FOR AERIAL APPLICATIONS?
Urea is the best source of nitrogen for aerial application. Because urea has the highest analysis (46% nitrogen), it has the lowest application cost per pound of nitrogen. The uniform area granules mean that applications can be accurately calibrated and evenly spread. Urea can be practically dust-free and, under most conditions, it does not absorb moisture and cake up. HOW DOES UREA COMPARE WITH AMMONIUM SULFATE? Urea has over twice as much nitrogen as does ammonium sulfate; 46% versus 21%. That means there is more than twice as much nitrogen as per ton of fertilizer. In addition, urea is less acid forming, is more water soluble and less corrosive. Ammonium sulfate does supply sulfur, but it is usually less expensive to apply urea and a sulfur material such as elemental sulfur. HOW DOES UREA COMPARE WITH AMMONIUM NITRATE? Urea contains about one-third more nitrogen, is less corrosive than ammonium nitrate and is less prone to caking. In addition, all the nitrogen is in the ammonic form
