Title:
SANDY SOIL WATER REPELLENCY REDUCTION
Document Type and Number:
WIPO Patent Application WO2003050061
Kind Code:
A3
Abstract:
Certain novel formulations of turf additives that act in such a manner as to permit proper amounts of moisture to contact root systems in order to reduce dry spots within highly managed turf areas and/or lawns. It is theorized that the accumulation of humic acid (and other natural byproduct deleterious compounds) at the topsoil surface in most cultivated grassy areas including sandy soils (such as, in particular, golf greens), results in the production of an effective organic waxy coating on the soil components. Such a coating is hydrophobic in nature and thus dries out the soil itself. The inventive formulation thus permits removal of such accumulated humic acid (and other compounds) from the topsoil to the level necessary to provide effective moisture penetration for sustained grass growth therein (hereinafter referred to as "redistributes"). Methods of providing such beneficial removal of humic substances from target sandy soils are also contemplated within this invention, as well as specific test hydrophobic sand formulations.
