0 a chemical compound in the form of a white powder, often used as a fertilizer (= substance to make plants grow) and in explosives (formula NH4 NO4)
Treatments include ammonium nitrate (closed circles), sulphur-coated urea (open circles), composted dairy manure (closed triangles), and poultry litter (open triangles).
Of the manufactured products, sulphur-coated urea is a slow release alternative source of nitrogen to ammonium nitrate.
Nitrogen was applied in the form of ammonium nitrate at a rate of 60 pounds per acre.
Ammonium nitrate fertilizer was applied at seeding and broadcast top-dressed at the 4-leaf stage.
Of the manufactured products used in the present study, ammonium nitrate is the most economical and rapidly acting.
Nitrogen was applied at the rate of 60 pounds per acre in the form of ammonium nitrate.
But from a crop production standpoint, ammonium nitrate provides the greatest crop scorch potential.
The application of chemical fertilizers such as ammonium nitrate and urea results in an increase in soil acidity.
