FAQ
Frequently Asked Questions
No. Ammonification is a specific chemical process within the broader decomposition of organic matter, focused solely on the release of nitrogen as ammonia/ammonium.
Primarily bacteria and fungi (decomposers) found in soil, water, and sediments.
Ammonification produces ammonia/ammonium from organic matter. Nitrification is the subsequent process where other bacteria convert that ammonia first into nitrite and then into nitrate.
It converts organic nitrogen, which plants cannot use, into inorganic ammonium, a form that plants can absorb, thus recycling nitrogen in ecosystems.
The process by which organic nitrogen is converted into ammonia or ammonium compounds by bacteria.
Ammonification is usually technical/scientific in register.
