 Price  break  up  Sandeep  Thumb Up  
 please.
 
 surely  looks  doable  after  you  posted  the  gram  measure.  Nice  going.
 What  matter  is  rest  of  the  percentage?

 Sandeep  I  should  have  typed  no  need  to  chelate  any  other  cation  but  iron  !

 Thanks,  that  is  a  big  load  of  from  my  head.
 Btw  which  chelator  do  you  use

 EDTA
 Then  DTPA
 
 Then  someone  I  know  suggested  DTPA  +  EDTA  ups  the  chelation  !  So  tried  that.
 I  felt  better  and  the  plants  grew  abundantly  as  usual.
 
 Then  Fulvic  acid.
 
 I  am  very  happy  with  fulvic  acid  for  now  as  I  have  an  inexhaustible  stock  !

 Ohhhhh  i  hate  chemistry......  I  never  thought  my  hobby  will  pull  me  to  it  again....  Sandeepgi  excellent  work.  i  think  we  need  to  have  a  workshop  on  'how  to  make  liquid  fertilisers  at  home'  on  any  of  our  iah  meets.

 EDTA  has  higher  %  of  iron,  DTPA  is  more  stable,  maybe  togather  they  work  well,  God  knows.  
 Seachem  claim  that  iron  in  Ferrous  state  is  more  easily  assimlated  by  plants.  Hence  they  use  ferrous  salts.
 BTW  could  not  find  any  informaion  on  chelation  by  fulvic  acid,  any  links.  
 I  hated  chemistry  specially  at  Graduate  stage,   became  a  CA  so  that  I  did  not  have  to  study  chemistry.
 So  much  so  for  tryimg  to  get  rid  of  cmemsitry

 Thanks  Sandeep,  will  be  patient.
 
 The  question  was  on  percentages  `%  in  mixture`,  they  dint  add  upto  100,  so  want  to  know  whats  the  rest.  Or  is  it  a  solution  that  you  are  making?

 The  %  in  mixture  is  weight  of  say  iron  in  total  mix,  they  will  not  add  up  to  100.
 
 Fe  gluco  contains  12.46%  of  iron  so  if  i  use  8.6  gm(8600mg),  the  iron  will  be  1072  mg.
 The  weight  of  total  mix  is  11.04gm,  so  the  %  is  9.7%  of  total  mix.
 
 The  ppm  given  are  a  better  guide,  all  calculations  are  based  on  ppm,  the  ratio  are  misleading.
 Fe  %  in  Fe  DTPA  is  6.98%  AND  IN  Fe  gluco  is  9.7%.
 But  when  13  gm  of  Fe  DTPA  or  8.6  gm  of  FE  gluco  are  dissloved  in  1  lit  of  water  both  will  give  1077.7  ppm  of  iron  in  bottle.

 Sandeep  the  advantage  of  Fulvic  acid  is  -  one  molecule  of  fulvic  acid  has  multiple  chelation  points  so  more  than  one  atom  of  cation  can  be  bound  to  one  molecule  of  fulvic  acid.
 Molecular  weight  of  fulvic  acid  -  dunno  !
 The  best  part  of  that  chelation  is  it  does  not  break  down  if  the  solution  is  alkaline,  unlike  humic  acid  which  needs  an  acid  medium.
 
 Both  will  chelate  NH4+  !!!
 
 Now  remember  all  about  water  changes  the  first  couple  of  weeks  after  using  commercial  products  ?
 Use  soft  water  blah  blah  blah  ....

 Yes,  on  further  reading  it  seems  to  be  the  best  chelator  around.
 I  can  find  out  the  molecular  weight  of  Fulvic  acid,  what  I  wanted  to  know  was  the  ratio  Fulvic  acid  to  iron  compound.
 Like  for  mixing  with  DTPA  I  think  both  are  mixed  in  ratio  of  their  molecular  weights.
 However  my  present  supply  of  Ferrous  gluconate  will  most  probably  outlast  me.
 Might  use  Fulvic  acid  in  my  next  life.  Very Happy

 Now  if  they  are  chelating  ammonium,  does  it  mean  that  plants  are  able  to  absorb  it  better?
 OR  i  am  thinking  in  reverse  Very Happy

 Plants  use  up  less  energy  to  assimilate  N  from  NH4+  than  from  NO3-  !

 Ooooh  man  this  is  walk  back  in  the  chemistry  class  Very Happy.
 
 Watching  it.  I  am  sure  lot  of  ppl  would  be  interested  in  buying  it  too  So  CSM  India+  Wink
