Other N-fertilizer choices include ammonium sulfate, calcium nitrate, ammonium nitrate and diammonium phosphate. Anhydrous ammonia, NH 3, is the most basic form of N fertilizer. Ammonia, a gas at atmospheric pressure, must be ... used source of N fertilizer for corn production in N. America. Unfortunately in Canada escalating insurance costs over
ATS and ammonium sulfate (AMS) contain both nitrogen and sulfur, however in different amounts. AMS also differs from ATS in that all the sulfur in AMS is immediately available to plants in the sulfate form, whereas ATS contains no sulfur in the sulfate form, but changes to sulfate after application to the soil. ATS (NH 4) 2 S 2 O 3 12-0-0-26S
Ammonium Sulfate Fertilizer – 20.5% Nitrogen. Nitrogen is not the only chemical needed for crops to thrive and grow. So in areas that require both nitrogen and sulfur, farmers use ammonium sulfate. This dry granular fertilizer delivers nitrogen entirely from ammonia and is excellent for corn crop fall plow-down and spring pre-plant.
Unlike urea, ammonium sulfate is not subject to volatilization on neutral or acidic soil — the optimum soil pH range for corn and most other crops. In other words, ammonium sulfate safely stays on the soil surface until incorporated via rainfall or irrigation.
At four of the 12 new corn site-years where grain yield was measured in the year of S fertilizer product application (spring pre-plant S fertilizer application), sulfate-based S fertilizers (polyhalite, gypsum, and ammonium sulfate) on average yielded 1,924 kg ha −1 more than the control treatment and 1,890 kg ha −1 more than the elemental ...

The ammonium sulfate fertilizer or sulfate of ammonia ((NH 4) 2 SO 4; sulfate is also spelled sulfate) is sometimes called ammosul or further abbreviated as AS or AMS. It is a chemical compound that is primarily used as a nitrogen fertilizer with other minor uses. It occurs in crystals with a particle size that is variable, colored white to beige (IPNI 2012).
one of the reasons why ammonia is the foundation for many other nitrogen fertilizers such as urea, urea-ammonium nitrate (UAN) solutions, ammonium sulfate, and calcium nitrate, as shown in Figure 1B. The discussion in this article will focus on the main sources of nitrogen fertilizer applied in the United States,
Broadcasting granulated urea, ammonium sulfate or ammonium nitrate across growing corn can cause leaf spotting or edge browning when fertilizer granules fall into the corn whorl. Damage will be greatest with ammonium nitrate, but that product is not readily available in Iowa, and damage from ammonium sulfate is greater than with urea.
Therefore, ammonium sulfate makes an excellent topdressing material for wheat and pastures. In addition, it will serve as a fall plowdown fertilizer for corn if applied after soil temperature at the 4-inch depth is 50 or less. It is also a source of sulfur, an essential plant nutrient.
Recent research has shown that an N-only starter such as ammonium sulfate also works well in these high fertility situations. ... on the basis of soil analysis, to neutralize soil acidity is given in the soil test report. In no-till …
Ammonium Sulfate. Ammonium sulfate remains one of the most popular nitrogen fertilizers used worldwide. As a fertilizer for alkaline soils, ammonium has many applications. Ammonium ion, when released in the soil, generates a small quantity of acid that decreases the soil's pH while also providing necessary nitrogen for plant growth.
