Capillary or water holding pore space is made up of small pores that hold water against the force of gravity retaining much is it for use by the plant.  Non-capillary or air holding pore space is made up of larger pores. When drained of water these pores fill with air providing oxygen to the root zone.  The physical measurements show that Lassenite Pozzolan Soil Amendments have a very high amount of total porosity and retain a very high amount of plant available water.  Therefore, Lassenite Soil Amendments will be very effective in increasing the capillary or water filled porosity of a root zone.  Test results determined that the addition of Lassenite Soil Amendments can beneficially change the water release pattern in the soil profile, eliminating localized dry spots and reducing irrigation requirements.  Many inorganic amendments maintain the ability to absorb moisture.  Lassenite has the unique ability to make the majority of this moisture available to the plant.

The ability of a soil amendment to aerate soil is a function of the compaction properties of the material.  Lassenite Soil Amendments blended into a soil horizon result in a dramatic improvement of porosity, attesting to Lassenite's inherent ability to improve the aeration of the soils and reduce compaction.

Ideally, a growing medium has an equal amount of air and water pore space after free drainage.  Lassenite is a tool designed to provide the Turf Manager with the ability to change the physical characteristics of the soil profile, depending upon existing site conditions and environmental influences, in order to produce the most desirable balance between air and water filled pore space.
