SILICA SAND G. R. FREE AND V. J. PALMER IT has been generally recognized that pore size and pore size distribution are important factors governing the rate of entrance of water into soils. There also seems to be a rather widespread belief that the movement of soil air is important. However, there are few experimental data that evaluate the effect of entrapment and escape of air upon water movement, and there is an even greater lack of data dealing with the practical importance of the problem. This laboratory study was undertaken as a preliminary investigation of the importance of air in the infiltration process. The purpose was to determine interrelationships between infiltration, air movement, and size of pore in order that the more practical work with field soils and natural rainfall could be planned better.
