IMPROVEMENTS IN THE MODE OF PREPARING AND APPLYING LIME FOR AGRICULTURAL PURPOSES
Year: 1884

I ISAAC BROWN of India Buildings Edinburgh in the County of Midlothian
Manure Manufacturer do hereby declare the nature of said Invention for
"IMPROVEMENTS IN THE MODE OF PREPARING AND APPLYING LIME FOR
AGRICULTURAL PURPOSES" to be as follows:-
Lime hitherto after burning has been broken up in structure and reduced to a
pulverized form by the application of water or moisture to it and afterwards
applied to the soil in large quantities varying from three to five tous an acre and at
a great cost in money horse and manual labour and yet with an imperfect action
whether employed as a manure or for enabling plastic soil to be more friable or in
a finer state of division as mould.
My Invention consists in the employment of finely divided or pulverised
anhydrous lime such preparation being effected either by grinding the burnt lime
stone as taken from the kiln into fine powder or by other means, such diminuted
or pulverised anhydrous lime is then brought into contact with the soil and covered
in or caused to be mixed therewith either by drilling ploughing harrowing or
otherwise. The powerful affinity that anhydrous lime in powder has for moisture
generates an extraordinary amount of heat and this action produced in the soil by
lime with the moisture contained in it is of the utmost importance as to the
chemical affinity of the lime combining with other constituants there present
and rendering then more efficacious as manure and also as a more powerful
disintegrator of the soil than lime applied in the ordinary way and at the same
time reduces the cost of liming land for agricultural purposes or that of grazing.

declare the nature of said Invention for "IMPROVEMENTS IN THE MODE OF
PREPARING AND APPLYING LIME FOR AGRICULTURAL PURPOSES" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Lime hitherto after burning has been imperfectly broken up in structure and
reduced to an imperfectly pulverised form by the application of water or exposure
to moisture and afterwards applied to the soil in large quantities frequently
injurious to crops and at a great cost in horse and manual labour and yet with
an imperfect action whether employed as a manure or for rendering plastic soil
more friable.
My Invention consists in the preparation and employment of finely divided or
pulverised anhydrous lime such preparation being effected either by grinding the
burnt lime stone as taken from the kiln into fine powder or by other means-Such
divided or pulverised anhydrous lime is then brought into contact with the soil and
covered in or caused to be mixed therewith either by drilling ploughing harrowing
or any other suitable means such as by a distributor attached to the plough giving
each furrow as turned over an equal portion for producing the necessary chemical
action with the constituents of the soil and for the conversion of every particle of
lime at once into a neutral salt thus rendering it as an inorganic constituent much
more efficacious as a manure than if applied in the ordinary way.
The powerful affinity that anhydrous lime in a finely divided state or powder has
for moisture generates an extraordinary amount of heat and this action produced in
the soil by lime with the moisture contained in the soil is of the utmost importance
and value in enabling or causing the lime with such affinity for moisture to produce
a better chemical action upon the manurial constituents present in the soil so as to
render them more efficacious as manure and also in causing a more powerful and
effective disintegration of plastic soils than is the case when lime is applied in the
ordinary way as hereinbefore mentioned.
Moreover by my Invention the cost of liming land for agricultural or grazing
purposes is largely reduced in comparison to liming it in the ordinary way.
The apparatus by which the lime is applied in accordance with my Invention
may be of any suitable kind which will effect the proper distribution of the
anhydrous lime for its uniform incorporation with the soil such as above described.
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:-
The preparation and employment or application of finely divided or pulverized
anhydrous lime as means for its uniform incorporation with the soil and for the
production of improved results in liming land for agricultural and grazing purposes
as herein before described.
