Ammonium nitrate itself is usually made by reacting ammonia with nitric acid. It does not occur naturally.
They spread them on the fields where it feeds the plants and make them grow bigger/faster.
The reason why ammonium nitrate is being used in explosives because ammonium nitrate is cheaper than the other ingredients/materials in making explosive devices. Unlike the others, you can purchase this thing easily without being asked for the exact usage. it is because farmers usually used this as fertilizers.
It was developed by Germans during a war to replace Chilean Nitrates as Fertilizer. A boatload of it blew up in Texas City. Mines now use it to replace dynamite. It is a whole lot less expensive. It is also used as fertilizer. Plants use the Nitrate part immediately. The Ammonia part slowly turns to a form of nitrogen that plants can use. Plants turn nitrogen into protein.

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.
For fertilizer.
they use it to neutralise acidic soil in fields
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.
no you cant. your thinking of the shake n bake one pot method and one has to use amonia nitrate, not urea.

Before tractors farmers used horses, mules, and oxen to till the fields.
Terrace farming
It doesn't do so directly. The poop breaks down and creates ammonia and mulm. This ammonia is deadly poisonous but nature has contrived to fix it by converting it into Nitrite and then to Nitrate by using naturally occurring bacteria in the environment and the 'cycled' filter. The plants can then use up the nitrate and mulm as they photosynthesise and grow.
