CAN FUSARIA ASSIMILATE ATMOSPHERIC NITROGEN? 
L. H. Pennington. 
(abstract.) 
During the spring and summer of 1907 several series of cultural experi- 
ments were made with a Fusarium (Fusarium zeae) to determine whether 
it is able to assimilate atmospheric nitrogen. Growth tests in many nutrient 
solutions and careful chemical analyses showed that this fungus cannot 
assimilate atmospheric nitrogen in solutions free from combined nitrogen 
nor in solutions containing combined nitrogen.
