Moisture Release 

For water to be available to the plant, water must move through the media or soil to the root, pass into the root, and then travel from the root to the leaf surface. During the dry down cycle, water is physically extracted from the medium or soil profile. 

Higromite has a total capillary porosity of about (68%).  The non-capillary pore space is made up of relatively large pores (18%) that conduct water under saturated conditions.  When drained, they are filled with air providing the oxygen that is necessary for root growth.
 

The capillary porosity is made up of small pores (50%)that hold water against the force of gravity, retaining much of it for plant use.  

The high overall capillary pore space contributes to excellent hydraulic conductivity and moisture retention & release.   

In the lab, increasing levels of energy are applied to samples to simulate dry down cycles. Water released between saturation, 0 Tension and 0.03 Bars, reflects free drainage.  Of greater importance is the water that is released from 0.03 bars to 2 bars, which is considered plant available water.
