Diagram Of The Nitrogen Cycle. Some processes benefit plant nutrition while others do not benefit or harm plant growth. This study was funded by the usgss toxic substances hydrology program.
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere terrestrial and marine ecosystemsthe conversion of nitrogen can be carried out through both biological and physical processes. However the abundant nitrogen in the atmosphere cannot be used directly by plants or animals. Nitrogen cycle is a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms.
Nitrogen fixation is the first phase of the nitrogen cycle.
1 some of the free molecular nitrogen of the atmosphere is fixed into nitrates non bio logically by lightening when oxygen of the air combines with nitrogen. Do you know what nitrogen is. Some bacteria such as rhizobium leguminosarium which live in the root nodules of leguminous plants can fix atmospheric nitrogen directly into the plant. Less no denitrification process p is decreased fewer denitrifying bacteria.
