Nitrogen: All Forms Are Not Equal - Cornell University
greenhouse.cornell.eduNitrogen form Plants have the ability to take up several chemical forms of nitrogen. The most common are: ammonium (NH 4 +), which has a positive charge; nitrate (NO 3-), which has a negative charge; and urea, ((NH 2)2CO), which has no charge. Many commercial fertilizer mixes contain a combination of all three nitrogen forms.
