Aeration of horticultural media is oft en reported to be a problem. The air filled porosity is generally considered as the quality determining factor for media and is generally determining the shape of the moisture characteristic curve. The objective of this study was to determine affects of different size and rate of pumice mixed with soil on the pore size distribution and bulk density of a mixture medium. Pumice of different size (

bulk density; pore size distribution; soil-pumice mixture media
