Abstract

SINCE 1927. Virtanen and co-workers1 have published results of numerous experiments which confirm and greatly extend the observation of Lipman2 that certain leguminous plants when fixing nitrogen excrete part of this into the quartz sand subtrate, and if a non-leguminous plant is present, it may utilize the excreted form. The extensive data Compiled by Virtanen and collaborators prove definitely that true excretion occurs with several of the legumes, but there exists an equally impressive body of experimental data which demonstrates conclusively that excretion is not universally obtained.
