    Ammonium nitrate is 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.

    How the Ammonium-nitrate ratio affects your plants | CANNA ...

    Most of the processes that involve ammonium and nitrate are part of the nitrogen cycle (figure 2). The most important step is the biological oxidation of ammonium to nitrate, known as nitrification. This process consists of various steps and is mediated by autotrophic, obligate aerobic bacteria, meaning that oxygen is required.
