Bilderback 2009 A nursery friendly method for measuring air filled porosity of container substrates.

The description for construction of a "home built" porometer apparatus to measure air-filled porosity (AFP) is described. This is an excellent device to monitor bark supplied between distributors, after new amendments are incorporated, or if a long time has lapsed since the last time bark was obtained from a supplier. See photos section for examples of it in use. T Bilderback Research Conference 54:212-215 (2009).
