Nitrogen Fixation and Other Microbial Activities in Soil on Antelope Range Station

This is a study of the symbiotic and non-symbiotic nitrogen fixing organisms on Antelope Range Station. Symbiotic nitrogen fixation is carried out by the native leguminous plants and the bacterial genus Rhizobium. This bacterium causes nodules to form on leguminous plants, and this symbiotic relationship is capable of utilizing gaseous nitrogen as a nitrogen source. Some experimentation was also done on a lichen found throughout the area studies. While speciation was not attempted, the lichen specimens were morphologically similar. These lichens also represented a symbiotic relationship, but in this case a nitrogen fixing blue-green algae formed a thallus with a fungal component. No other symbiotic nitrogen fixing associations were observed at Antelope Range Station
