An Introduction to the Nitrogen Cycle - Great Lakes Aquarium
glaquarium.orgnitrogen cycle is one of the biogeochemical cycles and is very important for ecosystems. Nitrogen moves slowly through the cycle and is stored in reservoirs such as the atmosphere, living organisms, soils, and oceans along its way. Most of the nitrogen on Earth is in the atmosphere. Approximately 80% of the

Tell how we get the nitrogen we need to
Nitrogen Basics – The Nitrogen Cycle
nmsp.cals.cornell.eduNitrogen fertilizer is expensive and losses can be detrimental to the environment. Efficient use of N by meeting crop needs while avoiding excessive applications of N is an important goal. This fact sheet provides a brief overview of the important components of the N cycle to aid in reaching that goal. Nitrogen Cycle

THE WATER CYCLE
www.mustangps.orgThe final aspect of nitrogen cycle is the process of denitrification. This process is performed by a variety of microscopic bacteria, fungi and other organisms. Nitrates in the soil are broken down by these organisms and nitrogen is released into the atmosphere. This …
Hydrology Basics and the Hydrologic Cycle
ext.vt.eduphosphorus, while groundwater can transport nitrogen and discharge contaminated waters to streams and rivers as baseflow. Because transport of nonpoint source pollution is mainly driven by the movement of water, an understanding of hydrology and the hydrologic cycle is critical to managing our water resources to support human needs.
