it affects the nitrogen cycle as the leguminous plants have nitrogen-fixing bacteria on their roots and these nitrogen-fixing bacteria help to collect nitrogen which is transferred to animals when these leguminous plants have been eaten.
Planting leguminous plants
these are the such plants that fix the nitrogen in the soil
Some plants are leguminous and have root nodules by which they are able to directly absorb the nitrogen from the atmosphere. If the are not leguminous, they get the nitrogen from the soils via their roots. For the same purpose of supplying nitrogen to the plants, farmers also add nitrogenous fertilizers to the soil which provides sufficient amount of nitrogen to the plants
Rhizoobium or nitrogen fixing bacteria lives in the roots of leguminous plants.leguminous plants are not able to use atmospheric nitrogen as sush,so these bacteria convert nitrogen into simpler forms i.e nitrates and nitrits which are easily used up by these plants.
They have nodules on their roots which contain nitrogen fixing bacteria. These take the nitrogen from the air and convert it to nitrogen compounds in the soil which plants use as nutrients. In short, using leguminous plants increases the fertility of the soil.
these are found in the soil and in the roots of leguminous plants
Nitrogen fixing Rhizobium bacteria.
Because leguminous plants are capable of fixing free nitrogen from the air with help of their root nodules. Thus soil get rich in nitrates in those places where these plants are grown.
Usually Rhizobium or Bradyrhizobium.
There are symbiotic nitrogen fixing bacteria in the root nodules of leguminous plants. They can fix atmospheric nitrogen into ammonium compound and supply the nitrogenous compounds to the plant.
Nitrogen fixing bacteria are common in the roots of leguminous plants like Melilotus,Trigonella, ground nut etc. and some Gymnospermous plants like Podocarpus
The root nodules of leguminous plants like gram,pulses,etc. contain nitrogen-fixing bacteria,rhizobia, which help in fixing nitrogen in the soil for the plants to absorb.Nitrogen is essential for the growth of plants.
