The  Woburn  Field  Experiments,  1903. 
cireninstances  stated,  was  a failure,  and  it  was  decided, 
therefore,  to  take  cleaning  crops  again  for  the  following  year 
in  order  to  get  the  land  into  better  condition  and  tilth.

' Manured  until  1899— once  in  the  rotation— by  feeding  off  roots  with  decorticated 
cotton  cake  and  maize  meal  respectively. 
» Unmanured  since  1885. 
In  1903  all  plots  top-dressed  with  1 cwt.  per  acre  nitrate  of  soda. 
Rotation  Experiment  {Laxsome  Field),  1903. 
Wheat  followed  the  beans  of  1902  which  had  been  taken 
when  the  clover  failed.  After  the  bean  stubble  was  ploughed 
and  the  land  cleaned,  grey-chaff  Browick  wheat  was  tlrilled  at 
the  rate  of  9 pecks  per  acre  on  October  22,  1902.  This 
received  no  manuring  ; the  crop  was  cut  on  August  20,  1903, 
and  carted  and  stacked  on  August  31.  The  weights  are  given 
in  Table  IV.,  page  29;).  The  produce,  it  will  be  seen,  was 
very  low,  being  little  more  than  on  the  continuous  wheat  plot 
of  Stackyard  Field  manured  with  nitrate  of  soda  only  (plot  3). 
Plot  4,  which  has  been  noticed  before  to  give  abnormal  results, 
was  the  higliest,  though  un manured,  and  no  real  deduction 
could  be  drawn  this  j’ear.  Indeed,  the  inequalities  of  the  land 
point  to  the  need  of  abandoning  this  as  an  exact  experiment. 
The  valuation  of  the  corn  showed  the  whole  to  be  inferior  ; 
the  samples  were  weak  and  yellow  in  appearance,  being  not  at  all 
good  milling  wheats.  This  was  due  mainly  to  the  bad  weather.
