N2  - A simplified filter paper method of determining the 15-atmosphere percentage in soils has been tested over a range of soil textures from sands to heavy clays. The regression of filter paper determinations against pressure membrane determinations of the 15-atmosphere percentage for the 34 soils gave the equation- y  =  1.03x  +  3.0  (r = 0.99 and P<0.001) where y = 15-atmosphere percentage (filter paper) x = 15-atmosphere percentage (pressure membrane). The results given by this simplified method indicate that it should be acceptable to agronomists and ecologists for field studies where facilities are limited.
