Since nitrogen fertilizer use is likely to be curtailed by federal mandate to minimize damage to estuaries and other oceanic environment (there are a number of other sites on the web dealing with this topic, search for sites dealing with the dead zone) the use of this organism may provide a method for farmers to retain high agricultural productivity while still meeting new regulations likely to be imposed.
