The total value of the agricultural output of England and
Wales in 1925, which has been estimated above at £225 millions,
is equivalent to an average gross output of fully £8 10s. per acre
on the total area under crops and permanent grass, after making
allowance for the rough grazings on which a substantial pro-
portion of the sheep flocks as well as some other stock are kept.
In the report on the 1908 Census a similar figure was given which
then worked out at £4 10s. per acre, but this applied to the whole
of Great Britain.
These products are not, of course, entirely the output of the
soil of this country alone. As already explained store stock
imported for fattening in this country are treated as home-bred
stock, while there are considerable purchases of corn offals,
oil cakes and other feeding stuffs and also of artificial
fertilisers either imported direct or manufactured from imported
materials. It is not possible, however, to say what quantity
of these feeding stuffs and fertilisers is used in England and Wales.
At a later date the production of Great Britain will be available
in the Industrial Census of Production and some rough approxi-
mation of the proportion used in England and Wales and in
Scotland may be possible.
