  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Nitrification  \Ni`tri*fi*ca"tion\,  n.  [Cf.  F.  nitrification.  see 
  {Nitrify}.] 
  1.  (Chem.) 
  a  The  act  process,  or  result  of  combining  with  nitrogen 
  or  some  of  its  compounds. 
  b  The  act  or  process  of  oxidizing  nitrogen  or  its 
  compounds  so  as  to  form  nitrous  or  nitric  acid. 
 
  2.  A  process  of  oxidation,  in  which  nitrogenous  vegetable  and 
  animal  matter  in  the  presence  of  air,  moisture,  and  some 
  basic  substances,  as  lime  or  alkali  carbonate,  is 
  converted  into  nitrates. 
 
  Note:  The  process  is  going  on  at  all  times  in  porous  soils 
  and  in  water  contaminated  with  nitrogenous  matter,  and 
  is  supposed  to  be  due  to  the  presence  of  an  organized 
  ferment  or  ferments,  called  nitrification  ferments.  In 
  former  times  the  process  was  extensively  made  use  of  in 
  the  production  of  saltpeter. 
 
  From  WordNet  r  1.6  [wn]: 
 
  nitrification 
  n  :  the  oxidation  of  ammonium  compounds  into  nitrates  by  soil 
  bacteria
