Improvements in and relating to Artificial Manures or Fertilizers.
I, ARTHUR GLADSTONE, of Dinsdale Lodge, Seaton Carew, in the County of
Durham, Ship Owner, do hereby declare the nature of this invention to be as
follows:-
My invention relates to artificial manures and fertilizers and has for its object to
provide a cheap and efficient base or carrying medium for the fertilizers, having in
itself a beneficial effect upon the soil, and consists in the utilization of common slag
or the bye product or waste from blast furnaces for this purpose.
To this end I reduce the slag to a powder or fine state of diminution and combine
with it any of the usual and well known fertilizers such as phosphates, potash,
sulphates, nitrogenous matters and so forth, these ingredients being added to the
common slag before, after or during the milling or reducing process, and either in
a dry or liquid state.

COMPLETE SPECIFICATION.
Improvements in and relating to Artificial Manures or Fertilizers.
I, ARTHUR GLADSTONE, of Dinsdale Lodge, Seaton Carew, in the County of
Durham, Ship Owner, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
My invention relates to artificial manures and fertilizers and has for its object
to provide a cheap and efficient base or carrying medium for the fertilizers, having
in itself a beneficial effect upon the soil and consists in the utilization of common
slag or the bye product or waste from blast furnaces for this purpose.
To this end I reduce the slag to a powder or fine state of diminution and combine
with it any of the usual and well known fertilizers such as phosphates, potash or
kainit, sulphates, nitrogenous matters and so forth, these ingredients being added
to the common slag before, after or during the milling or reducing process, and
either in a dry or liquid state.
The grinding and mixing of the materials may be accomplished in any convenient
manner and by the assistance of any of the well known machines for performing
these processes.
The proportion of the fertilizers added to the slag may be varied according to
circumstances, such as the kind and strength of the fertilizers used and the nature

page_text: of the land to which the manure is to be applied. To give an instance, I have
used a combination of 14 cwt. of powdered common slag to 6 cwt. of fertilizer but
I do not bind myself to these proportions.
The common slag itself has as before described, a beneficial effect upon the soil
as a fertilizer and apart from this effect it tends to lighten heavy soils and by its
use small quantities of strong fertilizers may be spread over a large area in an
efficient manner, the common slag preventing a too rapid diffusion of the fertilizing
agents employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1-The use in combination with and as a base or carrying medium for artificial
manures or fertilizers, of common slag or the bye product or waste from blast
furnaces, substantially as set forth.
Dated this 15th day of December 1897.
