The majority of these investigations mainly focused on the effect of layering soils on AWHC and on plant growth without considering the mechanisms by which textural layering changes the plant root distributions and water consumption within differently layered soils, particularly in regard to layer thicknesses.
The AWHC is the volume of water stored within the rooting zone as represented by the difference in water content between the field capacity (FC) and the WP.
The AWHC values for soil columns from each experimental trial are reported in Table 2.
Dara is the director of the AWHC and a long-standing member of the Tillery community and CCT.
Raven also gave a donation to the AWHC to provide financial support for the next student when the stipend was no longer available.
Finally, although lAs significantly altered the physical properties of unamended sands, compared with SP they were not as effective at sufficiently increasing the AWHC of sand rootzone mixtures.

Consequently improved water acceptance (as seen after heavy rain) and the AWHC of the soil were increased.

AWHC needed an improved system that would move scrap sheet metal faster, last longer, and require little or no maintenance.
A local distributor introduced AWHC to a new design called the Pumper, made by Numatics Actuator of Franklin, TN.
