  1. 1. Wayne E. Swann NutriGrown, LLC TEDCO/Chesapeake Bay Foundation Showcase Matrix Based Soil Additives for Reduced Nutrient Leaching
  2. 2. Problem <ul><ul><li>Fertilizer Use </li></ul></ul><ul><ul><ul><li>25 billion lbs of N: 8 billion lbs of P use in US/yr </li></ul></ul></ul><ul><ul><li>Turf Grass: ~ 30 million acres - 1.5 million acres golf courses </li></ul></ul><ul><ul><ul><li>+400,000 acres lawn/yr </li></ul></ul></ul><ul><ul><ul><li>5 million lawns/CB area </li></ul></ul></ul><ul><li>Manure use </li></ul><ul><ul><ul><li>5% of US cropland </li></ul></ul></ul><ul><ul><ul><li>400,000 tons chicken/yr/MD </li></ul></ul></ul><ul><ul><li>Leaching </li></ul></ul><ul><ul><li>Non-Point Source </li></ul></ul><ul><ul><li>pollution responsible for up to 90% of N and P </li></ul></ul>
  3. 3. 15 Percent of all American Fertilizer use is for Lawn Care Did you know? India, with a population more than twice that of the United States, used about the same amount of fertilizer on all of its food crops as Americans use on their lawns.
  4. 4. Background <ul><ul><li>Matrix based soil additive to reduce nutrient leaching </li></ul></ul><ul><ul><li>USDA/ARS Northwest Irrigation/Soils Res. Lab </li></ul></ul><ul><ul><li>ARS Researchers: James A. Entry, Robert E. Sojka </li></ul></ul><ul><li>Eight Research Studies (partial list) </li></ul><ul><ul><li>Water Air Soil Pollution (2007) 180:283-292 </li></ul></ul><ul><ul><li>FLRC Symposium (2009) New Zealand </li></ul></ul><ul><li>NutriGrown </li></ul><ul><ul><li>Formed to commercialize the Matrix </li></ul></ul><ul><ul><li>TEDCO Grant/June 2010 </li></ul></ul>
  5. 5. The Matrix <ul><li>Natural organic and inorganic high ionic exchange compounds </li></ul><ul><ul><li>starch, cellulose, lignin, chitosan, and others </li></ul></ul><ul><ul><li>+ iron sulfate; iron citrate; aluminum sulfate </li></ul></ul><ul><li>Matrix binds N and P </li></ul><ul><li>Slowly degrades and nutrients gradually become available to plants </li></ul>
  6. 6. Typical Greenhouse Trial Set up Matrix/ Fertilizer MBF1 MBF2 MBF3 MBF2 +Al -Fe MBF3 +Al -Fe MBF3 -Al +Fe SRF CTRL
  7. 7. Eight Greenhouse Fertilizer Trials <ul><li>Matrix Formulations reduced N and P leaching by over 80% vs. Osmocote, Avail, Polyon, and ESN </li></ul><ul><li>Reduced leaching shown in three soil types </li></ul><ul><li>Plant growth </li></ul><ul><ul><li>similar to Osmocote </li></ul></ul><ul><ul><li>lower than others </li></ul></ul><ul><ul><li>additional nutrients – </li></ul></ul><ul><ul><li>greater plant growth </li></ul></ul><ul><ul><li>SRF with Matrix </li></ul></ul><ul><ul><li>increases plant </li></ul></ul><ul><ul><li>growth minimizes </li></ul></ul><ul><ul><li>leaching </li></ul></ul>
  8. 8. CTRL MBF1+ Fe Citrate MBF3+ Fe Citrate MBF1 MBF3 Matrix layer Manure layer Bermuda Grass Manure Greenhouse Trials
  9. 9. Nitrate and Ammonium Leaching Manure Greenhouse Trials
