Explain the role of nitrogen fixing bacteria to providing soil fertility?

i am pretty sure that it converts atmospheric nitrogen N2 to NH3 (fixed nitrogen) that the plants use for growth


I'll hav e a look in my text books and get back to you





ok; so i checked it out and what i stated above is just part of the nitric acid cycle. this part is N2 Fixation and there are 3 types, aerobic (by organisms such as Cyanobacterium) anaerobic (eg Clostridium), there is also symbiotic ( eg Rhizobium)


There are also other processes in the Nitrogen Cycle such as Nitricifation (NH4+ to NO3-) and Dentrification (NO3- to N2)


you should do a little research I cannot explain it all here it is a very involed concept.


but primarily Nitrogen is an energy source for plants and bacteria make this available to plants by converting it to forms that can be used by the plant eg N2 to NH3

you just did.
