Factors affecting Nodule Formation in Legumes 

The growth of all organisms depends on the availability of mineral nutrients, and none is more important than nitrogen, which is required in large amounts as an essential component of proteins, nucleic acids and other cellular constituents. All legumes have the capacity to fix their own nitrogen. Rhizobia bacteria combine with legume roots to form nodules that, in turn, carry on nitrogen fixation  
the process by which legume plants obtain (fix) the nitrogen they need from the gaseous nitrogen in the air.
 Project description:
In this project, you will make use of a soil bacterium of the genus Rhizobium and a host legume to demonstrate the effects that soil microbes can have on soil fertility and nutrient availability.
