NH₄NO₃

Best solid granular fertilizer to provide crops with phosphorus and nitrogen that are easy to uptake. These nutrients are vital for quick sprouting and vegetation. A popular fertilizer since it provides half of the N in the nitrate form and half in the ammonium form. The nitrate form moves readily with soil water to the roots, where it’s immediately available for plant uptake
Ammonium nitrate is used commonly in fertilizers; in pyro techniques, herbicides, and insecticides; and in the manufacture of nitrous oxide. It is used as an absorbent for nitrogen oxides, an ingredient of freezing mixtures, an oxidizer in rocket propellants, and a nutrient for yeast and antibiotics.
