Abstract-The  study  was  carried  out  to  investigate  the effect  of  phosphate  fertilizer  application  on  manganese (Mn)  adsorption.  Composite  sandy  loam  and  loam  soil samples  (0-20  cm)  were  collected  from  Dalori  and Gongulong  and  analysed  for  their  texture  and  chemical properties.  Mn  adsorption  experiment  was  carried  out. Loamy soil  collected  at  Gongulong was  moderately acidic in  reaction,  moderate  in  electrical  conductivity  (EC), high  in  base  saturation,  moderate  in  organic  carbon,  low in  available  phosphorus,  and  low  in  DTPA  extractable Mn.  While  sandy  loam  soil  collected  at  Dalori  is  neutral in  reaction,  low  in  EC,  high  in  base  saturation,  low  in organic  carbon  and  low  in  DTPA  extractable  Mn.  For sandy  loam  soil,  there  was  no  definite  trend  in  the equilibrium  Mn  concentration  with  and  without phosphate  (P)  fertilizer  treatment,  with  increasing application  of  Mn  concentrations.  There  was  however  no difference  in  the  amount  of  Mn  adsorbed  by  the  soils when  P  fertilizer  was  added.  For  loam  soil,  there  was  no definite  trend  in  the  equilibrium  Mn  ion  concentration  of the  soils  with  increasing  application  of  Mn  levels  to  the soils  with  and  without  P  fertilizer  treatments.  There  was however  an  increase  in  the  amount  of  Mn  adsorbed  by the  soils.  There  was  no  difference  in  the  amount  of  Mn adsorbed  by  the  soils  when  P  fertilizer  was  applied.  Data were  fitted  into  Langmuir  and  Freundlich  equations. Loam  soil  without  P  conformed  to  Langmuir  equation, while  for  Freundlich  isotherm,  loam  soil  with  P treatment  conformed  to  the  equation. The  results  showed that  maximum adsorption  (b)  for  loam  soil  without  P  was 0.99mg/g  and  binding  strength  (K)  of  -214.92  ml/µg. While  for  Freundlich,  the  adsorption  constant  (K)  and (n)  were  1.28  and  -0.21  respectively.  This  study  have revealed  that  there  is  no  observable  effect  on  the  amount of  Mn  adsorbed  by  the  soils  after  P  fertilizer  was  applied and  on  the  other  hand  do  not  reduce  bioavailability  of Mn in  soil.
