In subject area:Agricultural and Biological Sciences The nitrogen cycle consists of biological processes involving fixation of atmospheric nitrogen into organic nitrogen (nitrogen fixation), release of organic nitrogen into the soil solution (mineralization), and conversion of ammonia into nitrate (nitrificat...

Stages of the Nitrogen Cycle Legume plants ( peas, beans and clover ) are home to nitrogen fixing bacteria. These convert nitrogen gas to nitrates which are nitrogen in a form that plants can use to make proteins. Non legume plants absorb nitrates from the soil. ...
If thisnitrogen cyclerepeated elsewhere, many of the world's forest won't be absorbing much CO 2. 如果这种氮循环不断重复进行, 那么世界上很多森林都不能再吸收二氧化碳. 期刊摘选 英英释义 Noun 1. the circulation of nitrogen; nitrates from the soil are absorbed by plants which are eaten by anim...
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. Encyclopaedia Britannica/Getty Images/HowStuffWorks Living things require nitrogen for ...
Figure 20.1.Schematic representation of the role of cyanobacteria in nitrogen cycle. Moreover, heterocystous cyanobacteria such asAnabaenaandNostochave specialized cells called heterocysts that are responsible for nitrogen fixation (Adams, 2000). Heterocysts are differentiated cells that lackphotosystem II...

Nitrogen Cycle – nitrogen is constantly on the move. Soil Test for Nitrogen Nitrogen is very important, so why not test for it? Most routinesoil tests do not include a test for nitrogen. The reason is that the nitrogen in soil changes too fast. By the time you get your results, the ...
