The process of converting a substance into ammonia or ammonium compounds, or treating with ammonia.
From ammonia + -ization (a process suffix), creating a noun that describes a chemical transformation; the suffix -ize became -ization to denote the action or process itself.
The -ization suffix is incredibly productive in English—it turns adjectives and nouns into processes: modernization, digitization, ammonization—each suggesting transformation or systematic change.
