ammonium nitrate
Yes. Urea, urea ammonium nitrate and ammonium thiosulfate can cause more damage from ammonia toxicity than ammonium sulfate or ammonium nitrate. For this reason, the former three sources are not recommended for applications in close proximity to …
At rates of several hundred pounds of ammonium sulfate per acre, the acidifying effect of ammonium sulfate would be in the order of hundredths of a pH unit. Based on a nitrogen rate of 140 pounds per …
When either ammonium sulfate or elemental sulfur is applied to provide the sulfur needs of a crop – with the nitrogen supplied by ammonium sulfate or other ammonium nitrogen fertilizers such as anhydrous ammonia, urea, or ammonium …
Here are 10 great reasons to use Sulf-N ammonium sulfate: Honeywell is the world’s largest single-site producer of ammonium sulfate, and a global leader in agronomic research and promotion of this product University-proven across a broad geography of field and …
While ammonium sulfate is more acidifying than anhydrous ammonia, urea, or ammonium nitrate, its acidifying effect on soil is significantly less than traditionally assumed. If applied to supply 100 percent of a crop’s nitrogen needs, ammonium sulfate …
