Abstract
A. I. Virtanen and M. Torniainen suggest that the discrepancies in their results and those of others experimenting on the excretion of nitrogen compounds from leguminous roots may be ascribed to the quality of the containers, and especially to their porosity. Observations show that the pots giving best results should be large and very porous.
