The Nitrogen CycleTechnology, AgFoundation, Stewardship
The ocean's nitrogen cycle is driven by complex microbial transformations, including nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the most abundant form of nitrogen in sea water but only accessible by nitrogen-fixing microbes. Denitrification and nitrification ar...

The first process of the nitrogen cycle isnitrogen fixation. This is the process of converting atmospheric nitrogen into usable compounds like ammonia, nitrates, nitrites, etc. This is done via several activities. The energy generated during lightning causes oxygen and nitrogen to combine to form ni...
Microbial processes in the nitrogen cycle The nitrogen cycle is a crucial process in the environment, as it involves the transformation and circulation of nitrogen in various forms. Microbial processes play a significant role in the nitrogen cycle, as they are responsible for carrying out key ...
nitrogen cycle nitrogen cycle The continuous process by which nitrogen is exchanged between organisms and the environment. Some of the atmosphere's free nitrogen combines with other elements to form compounds that are deposited in the soil. These are then converted by bacteria, in a process called...
Since nitrogen (N) is the nutrient most often limiting to plant growth, a large portion of the tripling of global crop production during the last 50 years--and associated economic development—is due to the widespread use of N fertilizers. The global ecological impact of N fertilizer production...
The nitrogen cycle is the system by which nitrogen is converted into different chemical forms, some usable to humans and animals and some not, as it circulates among the atmosphere, the land and the oceans.
challenge presented by the scope of the changing nitrogen cycle remains under-appreciated in both policy and scienti c circles, but already-observed impacts of such changes on biodiversity, climate and human health provide compelling reasons to exploit more fully options for nitrogen management and ...
