This study determined the porosity in the waste cork industry (C) and when such waste product had been composted during 4 (CC-4), 7 (CC-7), and 10.5 months (CC-10.5). The particle density of the intact and finely ground material differed significantly in all particle size ranges larger than 0.5 mm. The porosity of the cork substrates ranged from 80% to 94% of the total volume, according to granulometry and the degree of decomposition. However, large particles and less decomposed material with a high porosity had up to 10% of the total volume as occluded pores. The material's effective porosity varied slightly between the various particle sizes and degrees of decomposition, which ranged between 80% and 89%, having an average value of 85%. The ash content was highly correlated with the particle density of the finely ground material. Nevertheless, and due to occluded porosity, we cannot estimate the `'effective porosity'' from the ashes; therefore, we must resort to techniques that involve the displacement of a fluid, such as liquids or gas pycnometry or submersion.</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 701 NORTH SAINT ASAPH STREET, ALEXANDRIA, VA 22314-1998&lt;br/&gt;publisher: AMER SOC HORTICULTURAL SCIENCE</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ordovas, J</style></author><author><style face="normal" font="default" size="100%">Carmona, E</style></author><author><style face="normal" font="default" size="100%">Moreno, M T</style></author><author><style face="normal" font="default" size="100%">Ortega, M C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Characteristics of internal porosity of cork container media</style></title><secondary-title><style face="normal" font="default" size="100%">HORTSCIENCE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">ash content</style></keyword><keyword><style  face="normal" font="default" size="100%">effective porosity</style></keyword><keyword><style  face="normal" font="default" size="100%">particle density</style></keyword><keyword><style  face="normal" font="default" size="100%">total porosity</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1996</style></year></dates><publisher><style face="normal" font="default" size="100%">AMER SOC HORTICULTURAL SCIENCE</style></publisher><pub-location><style face="normal" font="default" size="100%">701 NORTH SAINT ASAPH STREET, ALEXANDRIA, VA 22314-1998</style></pub-location><volume><style face="normal" font="default" size="100%">31</style></volume><pages><style face="normal" font="default" size="100%">1177-1179</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The structure of cork (Quercus suber L.) bark presents a series of characteristics, suggesting that internal porosity is partly occluded.
