AP-42, CH 8.3: Ammonium Nitrate
Plants producing a solid ammonium nitrate product may employ all of the operations. All ammonium nitrate plants produce an aqueous ammonium nitrate solution through the reaction of ammonia and nitric acid in a neutralizer as follows: NH3 HNO3 → NH4NO3 Approximately 60 percent of the ammonium nitrate produced in the U. S. is sold as a …

It is widely accepted that the co-provision of nitrate with ammonium eliminates this toxicity, and that plant growth is maximized at a certain ratio of ammonium to nitrate depending on the species (Britto and Kronzucker, 2002). It remains a challenge to determine how the optimal nitrate and ammonium ratio is determined in association …

The alleviation of ammonium toxicity in plants
Nitrogen (N) is an essential macronutrient for plants and profoundly affects crop yields and qualities. Ammonium (NH 4 +) and nitrate (NO 3 −) are major inorganic N forms absorbed by plants from the surrounding environments.Intriguingly, NH 4 + is usually toxic to plants when it serves as the sole or dominant N source. It is thus important for …

Molecular mechanisms of ammonium transport and accumulation in plants
Plants are well adapted to low nitrogen soils and frequently ammonium is the preferred nitrogen source [1]. Localized nitrogen supply stimulates root growth, root branching and lateral root elongation, but most of the positive effects on root proliferation have been attributed to nitrate, rather than ammonium.

Ammonium Nitrate
Ammonium, nitrate, and phosphorus are plant-availabe nutrients that are found in wastewater and are frequently associated with excessive algae growth in surface waters. These nutrients can be removed by the plant–soil system but may require the harvest of plant materials. Under certain conditions, phosphorus can be bound to clay surfaces.
