In contrast,  in  the  lower  parts  of  the  catchment,  the  Rivers  Dun,  Blackwater,  and  Lower  Test,  and  the   Bow  Lake,  and  Lower  Itchen,  flow  over  tertiary  clay  geology  where  soils  are  more  prone  to  structural   degredation.   2.3.  Land  use  and  Population   The  Test  and  Itchen  is  a  largely  rural  catchment  and  the  majority  of  land,  approximately  1,100  sq  km   or  62%,  is  used  for  farming.       The   main   agricultural   activity,   accounting   for   80%   of   agricultural   land,   is   arable   farming   and   includes   the  production  of  wheat,  barley,  oats  and  oil  seed  rape.  There  are  also  a  number  of  mixed  farming   and   livestock   enterprises,   most   of   which   are   concentrated   in   the   lower   catchment   and   the   river   valleys.     The  river  valleys  are  also  home  to  the  watercress  industry,  which  relies  on  plentiful  supplies  of  high   quality  spring  water  for  its  watercress  growing  operations.   The   main   centres   of   population   within   the   catchment   are   Southampton,   Andover,   Winchester,   Eastleigh  and  Romsey.  The  catchment  population  is  approximately  725,000  (2011  Census)  with  the   highest  population  densities  in  Southampton,  which  creates  significant  pressure   on  water  resources   and  increased  levels  of  pollution  entering  the  Southampton  Water.
