Ammonia
Yes. Nitrogen is used for making many types of amide/amine-based chemical fertilizers. It is the main constituent of fertilizers like Urea & Di-Amino-Phosphate.
The chemical agent ninhydin is used as a catalyst for nitrogen based fertilizers and is sometimes found in ammonia based fertilizers used for non food based agriculture.
There are about seven kinds of fertilizers:Organic Fertilizer,Inorganic Fertilizer,Nitrogen-Based Fertilizer, Phosphorus-Based,Fertilizer,Potassium-Based Fertilizer, Liquid Fertilizers and Solid Fertilizers. Whirlston fertilizer machines can make most of them.
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.
They can either a) spread a nitrogen based fertilizer, or b) rotate to a crop that replaces the nitrogen in the soil.
Ammonia and Nitrogen based fertilizers are commonly used at homes and farms.
Fertilizers have helped farmers produce more and healthier crops.
Nitrogen and phosporus
Pea plants grow faster with phosphate-based fertilizers than with nitrogenous fertilizers. They have too much vine growth at the expense of peas and pods when the fertilizer is either balanced or nitrogen-heavy. Fertilizers such as 5-10-10 minimize nitrogen and put phosphorus and potassium in equal amounts since they respectively promote healthy, strong roots and disease-resistant body parts, especially fruits.
Nitrogen compounds are used to make ammonia based fertilizers. Ammonia helps the plants in the soil to generate nutrients when there is adequate water and air in the soil.

Nitrogen generators can be used for a variety of purposes. While not really meant for commercial use, nitrogen can be used to fill tires in cars and planes, preserve packaged food freshness, and are helpful for use in electric components.
