{{SignalTerm|type=DS|id=DS-00066|label=Ammonia production (mass)}} refers to the total quantity of ammonia generated globally through industrial and chemical processes. Ammonia is a critical compound widely used in agriculture as a fertilizer, as well as in various industrial applications. Its production is a significant component of the global nitrogen cycle and has implications for environmental and human systems due to associated energy use and emissions.

The relevance of monitoring ammonia production lies in its role as a driver of environmental pressures, including greenhouse gas emissions and nutrient loading. Understanding the scale and trends of ammonia production aids in assessing its contribution to anthropogenic environmental change.

Within the global context, ammonia production is influenced by technological, economic, and policy factors, making its measurement important for integrated environmental assessments and sustainable resource management.

== Geographic / System Context ==
Ammonia production occurs worldwide, with major industrial centers distributed across Asia, Europe, North America, and other regions. The geographic distribution reflects access to natural gas or other feedstocks, infrastructure, and agricultural demand. Production facilities are often located near agricultural zones or chemical industry hubs to optimize supply chains. This global distribution influences regional environmental impacts and resource use patterns associated with ammonia synthesis.

== Monitoring and Measurement ==
Monitoring ammonia production involves compiling data from industrial reports, national statistics, and international databases. Measurement conventions typically quantify production mass in metric tonnes (t) over defined time periods, often annually. Scientific institutions and agencies collect and verify production data through surveys, trade records, and energy consumption analyses. Life cycle assessment studies also contribute to understanding the environmental footprint of ammonia production processes.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
