Nitrogen dioxide.
Nitrogen
Nitrogen fixation is one process by which molecular nitrogen is reduced to form ammonia. This complex process is carried out by nitrogen-fixing bacteria present in the soil.
Radon gas is a naturally occurring radioactive element which can be produced by the decay of radium (which in turn is part of the decay chain of uranium) present in granitic rocks and shales and also soils derived from these two rock types.
nitrogen
All matter can turn into solid, liquid, gas, or plasma form.
they turn the nitogen gas into the nitrates and nitrites essential for the soil
Nitrogen
Soil bacteria!!!!
Bacteria fix nitrogen by taking the nitrogen in the air and turning it into a type of nitrogen that can be used by other organisms. This usually occurs in the form of ammonium.
Nitrogen gas (N2) is converted by nitrogen-fixing bacteria that live in the root nodules of Legumes into NH3.
Rhizobium bacteria absorb nitrogen gas from atmosphere and convert it into nitrogenous compounds called nitrates. the roots decompose the nitrates present in the root nodules mix with the soil enrich it with the nitrogenous compounds and hence increase the soil fertility.
Denitrification ya clown
Water in soil evaporates into a gas, then collects and turns dense forming clouds. Clouds are technically a part of the atmosphere.
Nitrogen fixing bacteria turns into what is called AmmoniaAnd the ammonia is therefore turned into a form of nitrogen that can be used by plants.
The main way nitrogen gas leaves the soil and gets into the air is through a process called denitrification. Denitrifying bacteria convert nitrate, a form of nitrogen found in the soil, back into nitrogen gas which is then released into the atmosphere. This occurs in oxygen-poor environments such as water-logged soils and wetlands.
denitrification
The three types of bacteria which are involved in the nitrogen cycle are nitrogen- fixing bacteria which change the nitrogen gas into ammonia. The next is nitrifying bacteria which changes the ammonia into nitrities and then the nitriites into nitrates. Then the plant absorbs the nitrates and uses them to continue growth. Then an animal may eat the plant receiving the nitrogen from it. But it must eventually get ride of it so it produces waste which goes back into the soil and is broken down by decomposers and fungi, which then turn it back into ammonia. The cycle then repeats itself. Extra nitrates are turned back into nitrogen gas by denitrifying bacteria.
