Patent Awarded to Starch-Based Soil Amendment

Zeba soil amendment has recently received a U.S. Patent. The product is designed to absorb moisture and water soluble nutrients, then release them over and over as demanded by turf plant roots.

Zeba was developed and is being manufactured and marketed by Absorbent Technologies, Inc. (ATI), based at Beaverton, Ore. Holders of the patent are the father-and-son team of William Doane, Ph.D., who developed the concept used for Zeba during his 32-year tenure with the United States Department of Agriculture, and Steven Doane, a chemist who helped further develop Zeba. Both are advisors to ATI.

Zeba can be applied:

  • as a seed coating to enhance germination;
  • as a soil amendment during initial seeding for faster germination and strong stand development; or
  • to reduce localized dry spots for improved water percolation and dispersion.K/li>

Made from natural cornstarch, Zeba is biodegradable, nontoxic and virtually odorless. Each particle can absorb up to 400 times its weight in water, then release and reabsorb water repeatedly as needed by the turf plant, remaining effective for up to one year. This action keeps water available to the plant, but prevents oversaturated conditions that can damage turf and decrease growth performance.
