Our bodies could not heal, grow or function without Nitrogen

|
|
Nitrogen is an important part of all life on Earth
|
|
|
Plants need nitrogen
|
|
|
Agriculture and farming practices can affect this cycle
|
Detailed explanation-1: -Nitrogen (N) plays an important role in crop plants. It is involved in various critical processes, such as growth, leaf area-expansion and biomass-yield production. Excess NUE can support good plant performance and better crop out-put.
Detailed explanation-2: -Much of the nitrogen applied to agricultural and urban areas ultimately enters rivers and nearshore coastal systems. In nearshore marine systems, increases in nitrogen can often lead to anoxia (no oxygen) or hypoxia (low oxygen), altered biodiversity, changes in food-web structure, and general habitat degradation.
Detailed explanation-3: -Bacteria play a key role in the nitrogen cycle. Some species of nitrogen-fixing bacteria are free-living in soil or water, while others are beneficial symbionts that live inside of plants.
Detailed explanation-4: -The five processes in the nitrogen cycle – fixation, uptake, mineralization, nitrification, and denitrification – are all driven by microorganisms.
