       N-VIRO ANNOUNCES SIGNIFICANT IMPROVEMENT IN 2004 FINANCIAL RESULTS

Toledo,  Ohio,  Monday,  April  4,  2005  -  N-Viro  International  Corp.  (OTC
BB/NVIC.OB) announced the Company's financial results for the fourth quarter and
year  ended  December  31,  2004.

Chairman  Phillip  Levin stated, "N-Viro is very pleased with its 2004 financial
results.  Our  2003  loss was over $1.5 million, but in 2004 it was only $71,000
and,  due  to  depreciation  and  other non-cash expenses, cash basis income was
approximately $500,000.  Fourth quarter 2004 earnings were $14,000 compared to a
$711,000  loss  in  2003."

"Beginning  in  May  of  2004,  our management and consulting team embarked on a
program to reduce operational costs by over $600,000.  Dan Haslinger, who became
CEO  this  past  January,  is  focused  on  continued  cost  reduction  and  the
development  of  additional  revenue  sources.  Our  independent  auditors  have
recognized  these operating improvements, as demonstrated by the removal of last
year's  going  concern  qualification  in  the  auditor's report.  The Company's
balance  sheet  is  greatly improved due to a successful private stock placement
effort,  the  proceeds  of  which  were  used  to reduce debt.  Recently elected
directors  Carl  Richard  and  Joe  Scheib have added valuable experience to our
team.  We are confident the positive trends initiated in 2004 will continue into
the  future,"  commented  Levin.

"N-Viro  also  has retained Quest Equities, LLC as a consultant charged with the
mission  of  enhancing  shareholder  value  in  the  near term.  We are eager to
advance  our  work with Quest and to pursue various initiatives which are on the
drawing  board.  As  Chairman it will be a great pleasure to address the Company
shareholders  at  our upcoming annual meeting in light of our improved financial
report.  Many  of  the changes that have been implemented are only now beginning
to  show  results.  As  our team continues its work our financial condition will
continue  to  improve,"  Levin  concluded.
