Product Description

Ammonium sulfate is a form of organic salt that has got several uses commercially. The very common use of the salt is as a fertilizer. This fertilizer has got 21% nitrogen and sulfur at 24%.

Primary use

Ammonium sulfate is usually used on different alkaline soils. When within soil, ammonium ion is then released so as to form acid which goes on to lower the soil pH balance. It also makes a contribution of the nitrogen that is very essential doe the growth of plants. There is a main disadvantage of using the ammonium sulfate is the fact that it has a nitrogen content which is very low relative to the ammonium nitrate and this elevates different transportation costs.

Control and legislation

In the year 2009 there was a ban imposed on the use of ammonium sulfate fertilizers because of reports that the fertilizer was being used by different militants to create explosives. In the year 2010, Afghanistan also banned the fertilizer for the very same reason.

This was one of the most widely used nitrogen fertilizers for the purposes of crop production even though it is not so commonly used today. However, it proves to be a very valuable fertilizer when nitrogen and sulfur are really required within the soil at the very same time. This is because of its high solubility which gives a great versatility for many agricultural applications.

Production

This has been produced for well over 150 years. At first, it was made using ammonia which was released as coal gas was manufactured so as to illuminate cities or coal coke that was used in steel production. It is made through the reaction of heated ammonia and sulfuric acid and the crystal size is determined by the conditions during the reaction. After the correct size is achieved, the crystals are dried and then screened to the particular particle sizes that are required. There are some materials which come coated with condition so as to reduce the incidence of caking and dust.

There are certain byproducts that have some level of ammonia and sulfuric acid and they are converted to the fertilizer used in agriculture. The color ranges quite a lot and so does the size of the particle.

Use in the agricultural field

This fertilizer is used when there is a need for a supplemental N and S so as to meet all the nutritional requirements of the growing plants. The fertilizer contains 21% N and therefore there are other fertilizers that are more concentrated. However, this is an amazing source of S and this has loads of essential functions in the plants and this includes protein synthesis.

The N fraction is also present in ammonium form and therefore the fertilizer is ideal for the flooded soils especially for rice production because the nitrate based fertilizers aren’t a good choice die to the de-nitrification losses.

Sometimes dissolved ammonium sulfate solution is used to the post emergence herbicide sprays s as to make them even more effective.

Management practices

When ammonium sulfate fertilizer is added to soil, it dissolves very rapidly into the components which are ammonium and sulfate. The fertilizer remains on the surface of the soil. The ammonium can be susceptible

After addition to soil, the ammonium sulfate rapidly dissolves into its ammonium and sulfate components. If it remains on the surface of the soil, it may be prone to gaseous loss in the alkaline conditions. It is therefore important to incorporate the matter into the soil soonest possible. It should also be applied before rainfall or irrigation.

Many plants are capable of utilizing the nitrate and ammonium form doe their own growth. In the warm soils, microbes usually start nitrification, which is the process of converting the ammonium into nitrate.

During this reaction, acidity is added and this in turn decreases soul pH when the use is repeated. Due to the nitrification process, ammonium sulfate fertilizer has an effect on the soil that is acidic but not because of the sulfate present within. The sulfate has an effect that is negligible on the ph. The potential of ammonium sulfate to produce acid is much greater than the N application within the ammonium nitrate. In ammonium sulfate, all N is converted into nitrate but only a half of N from the ammonium nitrate is converted.

Advantages 

These fertilizers have been proven to be amazing source of sulfate sulfur and ammonium nitrogen which is something that so many crops actually crave. Unlike the sulfur which is elemental, the sulfate sulfur is available to the roots of crops and this gives them quick access to the very essential nutrients that the crops need after the application. Ammonium nitrogen is also made available for the roots to take up. Nitrogen losses are also resisted from de-nitrification, volatilization and leaching.

This is a fertilizer that offers the crop tow nutrients that are very essential to crops and that is:

  • Sulfate sulfur
  • Ammonium sulfate

It is also a fertilizer which is very cost effective which many farmers desire. This is also a very high analysis fertilizer and it is able to pack some 900 pounds of plant food in every ton which makes it very efficient. Other agronomic advantages of ammonium sulfate fertilizer over other technologies include:

  • Very low susceptibility to loss of nitrogen through de-nitrification, volatilization and leaching
  • Has sulfur that is made available to plants very readily
  • It has a much higher nutrient efficiency
  • It is water soluble
  • Easy to handle
  • It can be blended with urea

When you use this fertilizer, your crops get immediate nutrition and it also assists them with uptake of other very critical nutrients. In most of the soils, when the soil has a high pH, the phosphorus solubility as well as critical micronutrients is reduced impending root uptake.

When the ammonium when the crops absorb ammonium, it acts so as to acidify the root zones and often unlocks phosphorus and the other key micronutrients line manganese, copper, iron, boron, and zinc. These benefits when combined with the different benefits that the sulfate sulfur gives and ammonium nitrogen helps improve the overall yield and nutrition of your crops.

The sulf N fertilizers have got sulfate sulfur, a kind of sulfur that the roots of a plant can be able to take up. Most of the products are only able to supply the sulfur that is elemental or the combination of the elemental as well as the sulfate sulfur and in such a case, the elemental sulfur only becomes available to the crops when it is converter into sulfate. When it is within the soil, the conversion may take some 90 days or several months and this leaves your crops yearning die sulfur when they are at the growth stages that are very critical. When you use the ammonium sulfate fertilizer, you will not have to wait as it has one hundred percent pure sulfate sulfur nutrition

In-depth positive impacts 

Nitrogen is able to enhance the yield more than any fertilizer nutrient and twenty one percent of the ammonium sulfate is actually nitrogen which is in a very efficient ammonium form. This fertilizer allows your roots to take up nutrients immediately. When there is a reduced tillage condition, it can be used on the surface of the soil and this can make your soil resist 3 major nitrogen loss causes which are:

  • Less leachable: the ammoniums ions are positively charged and are bound to the soil ions that are negatively charged and this makes the fertilizer susceptible to any leaching.
  • It resists volatilization: the fertilizer needs not be incorporate so as to minimize the volatilization loss in many of the soil types.
  • It immune to de-nitrification: de-nitrification process leads to nitrate loss in the soils that are not well drained but doesn’t affect ammonium availability in this fertilizer.

This is a very essential fertilizer where calcium within the soil is high and one of the biggest advantages of the fertilizer is the fact that it is much slower in its release and therefore it means it is released slowly over the growing season than other nitrate forms of nitrogen.

Use

Ammonium sulfate proves to be very helpful to all sorts of oil producing plants such as soybeans which are known to produce the soybean oil. These are the kind of plants that require some extra sulfates. The alfalfa crops also take sulfates so as to make amino acids that are sulfur bearing. The alfalfa and the legumes like the soybeans are highly benefited by the ammonium sulfate.

For one acre of land, 100-200 lbs. of ammonium sulfate fertilizer can be used as an application rate. Sulfur in the air is greatly reduced due to the environmental and pollution controls which means much less sulfur is actually emitted into the air. Even though that approach can help, acid rain still proves to be an issue as the pH can be very low in should and the best way to give it a boost is to use this fertilizer.

Disadvantages

Nitrogen is important for healthy vibrant plants but too much can cause damage as it over stimulates the growth of leaves while the rest of the parts are weekend and can be prone to pests, damage and disease.

Using it on soils that have a pH that is balanced can kill plants as the soil acidity is spiked in many cases.
