Farmers use ammonium nitrate as a source of nitrogen for plants, which is an essential nutrient for plant growth. It helps improve soil fertility, promotes healthy crop development, and increases crop yields. However, it is important to use it responsibly, as excessive application can lead to environmental issues such as water pollution.
Ammonium nitrate cannot be used directly in the preparation of ammonia because it is already a salt that contains both ammonium ((NH_4^+)) and nitrate ((NO_3^-)) ions. To produce ammonia, you need a source of nitrogen, hydrogen, or both that can react to form ammonia through processes like Haber-Bosch synthesis. Ammonium nitrate is typically used as a nitrogen fertilizer or in explosives, but not in the direct production of ammonia.
Ammonium nitrate is typically produced by reacting ammonia gas with nitric acid. The resulting solution is concentrated and then cooled to form solid ammonium nitrate crystals, which are then processed into various forms for commercial use, such as fertilizers or explosives.
Bacteria use a process called nitrification to convert nitrogen to nitrate. First, ammonia (NH3) is oxidized to nitrite (NO2-) by ammonia-oxidizing bacteria. Then, another group of bacteria called nitrite-oxidizing bacteria convert nitrite to nitrate (NO3-).
I'm sorry, but I can't assist with that.
The solution became anhydrous after applying a small amount of heat.
To convert ammonium nitrate to anhydrous ammonia, you need to heat the ammonium nitrate to a high temperature (above 170°C) in the presence of a catalyst such as activated carbon. This process will cause the ammonium nitrate to decompose into nitrous oxide and water vapor, leaving behind anhydrous ammonia as a gaseous product. The ammonia gas can then be collected and condensed for use.

It's not entirely true to say, "...regularly add nitrate fertilizers..." since farmers in the US generally select the kind of fertilizers to use based on the nutrient needs of the crop, timing of application, and price of the fertilizer material. Nitrate fertilizers are one form they can use to get nitrogen, possibly the single most important nutrient, to their crops. However, nitrates are not always the most appropriate form to use, and so they also use ammonium types such as urea or anhydrous ammonia.

You use a test kit and test for Nitrate/Nitrite/Ammonia. If you have either of the last two the cycle is not coping.
They used levee canals to bring water to their fields.

Before tractors farmers used horses, mules, and oxen to till the fields.
While urea is chemically similar to ammonia nitrate, it cannot be used as a direct substitute for making methamphetamine. The chemical processes required to convert urea into methamphetamine are different from those involving ammonia nitrate. Additionally, manufacturing methamphetamine is illegal and highly dangerous. It is important to avoid engaging in any activities related to the production of illegal drugs.
