Nitrogen - fixation plantsspan a encompassing ambit of ecosystems and uses , from reforestation and agroforestry to ornamental gardening and agriculture . These plant have the singular ability to convert atmospherical nitrogen , which is not instantly usable by most plants , into a form that can be assimilated into works tissues . This process is scream nitrogen fixation and is essential for plant growth and overall ecosystem health . The process of atomic number 7 fixation involves a symbiotic relationship between sure plants and bacterium . These bacterium , often go to the genusRhizobium , reside within nodules on the roots of the plants . The bacterium own the necessary enzyme to convert atmospherical nitrogen ( N2 ) into ammonia ( NH3 ) , which is then used by the plant for growth and development .

The list of nitrogen - fixing plants for agriculture is quite versatile and admit , among others : Beans : fava ( aka faba , broad ) , Medicago sativa , unripened ( aka French ) , runner , discipline , sweet , peanuts ( aka groundnuts ) , soybeans , cream , pitch-black - eyed , or violet - hulled beans , lupins , Lens culinaris , cowpeas , garbanzo .

mathematical group of Nitrogen - Fixing works

Legumes : The most well - eff group of nitrogen - repair plants is the legume family ( Fabaceae ) , which include plants such as beans , peas , lentils , soy , alfalfa , and trefoil . These plants form a symbiotic relationship withRhizobiumbacteria .

Actinorhizal plant : Another group of nitrogen - fixing plants includes alder , casuarina , and some other woody plants . These plant form symbiotic relationships with bacterium belong to the genusFrankia .
