Nitrogen
Root nodules are swollen structures present present in roots of leguminous plant which belong to family Fabaceae e.g. Pisum sativum , Medicago , Arachis . This family is the second largest family of Dicots and second most important family from economic point of view.These root nodules are formed by Bacteria named Rhizobium. These Bacteria are nitrogen fixing bacteria i.e. they trap N2 from air and convert it into NO3 which is used as fertilizer by plants. There is symbiotic relation between legume roots and N2 fixing Bacteria .They increase soil fertility .
Legumes have nirtifying bacteria in their roots, but mostly they are found in the soil.
carbon is the present in all organism.
The most common element found in all living things is not, as you would think, oxygen. It is carbon an can be found in every living organism. That is why organic material gives of Carbon and Oxygen as it rots or burns.
POTASSIUM
it is rhizobium
The nitrogen bacteria called RHIZOBIUM is found in the root nodules of leguminous plants.They are symbiotic.
The nitrogen bacteria called RHIZOBIUM is found in the root nodules of leguminous plants.They are symbiotic.
Legumes have nitrogen-fixing bacteria found in nodules on their roots. Thus, they add nitrogen fertilizer to the soil.
Nodules are hard to mine because they are found in very deep water

they are found growing the roots of plants e.g. cress
these are found in the soil and in the roots of leguminous plants
Chert is usually found in the form of nodules or lenses in bodies of limestones or dolomites.
In nodules on the roots.
oxides of manganese, nickel, copper and iron
The element nitrogen is found in protein molecules, and protein is richly supplied by many types of food including meat, fish, and dairy products such as cheese.
