PROVISIONAL SPECIFICATION.
Improved Manure or Fertilizer.
I, WILLIAM BROTHERS, of Higher Clews Chemical Works, Rawtenstall, in
the County of Lancaster, Manufacturing Chemist, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to provide a more efficient chemical fertilizer for
agricultural purposes than many of the manures at present manufactured.
It consists essentially of a manure or fertilizing compound composed of the solid
hydrogen-ammonium-carbonate or ammonium bi-carbonate (NH,CO,) or the sesqui
carbonate or other carbonate of ammonia.
In carrying out the invention I employ the hydrogen ammonium carbonate
preferably either in a crystaline or powdered state or it may be dissolved in
water and applied in a liquid state which will be convenient for horticultural
purposes.
I am well aware that sulphate of ammonia has been largely manufactured for
the purposes of a manure but the carbonate of ammonia I find to be a much better
fertilizer than either the sulphate of ammonia or nitrate of soda now largely
employed for the purpose.
(a) It is less soluble than either of these.
(b) It is more readily decomposed as required for plant life.
(c) It is more efficient as the whole weight of the article is utilized as a
plant food.

COMPLETE SPECIFICATION.
Improved Manure or Fertilizer.
I, WILLIAM BROTHERS, of Higher Clews Chemical Works, Rawtenstall, in
the County of Lancaster, Manufacturing Chemist, 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 :-
The object of this invention is to provide a more efficient chemical fertilizer for
agricultural purposes than many of the manures at present manufactured.
It consists essentially of a chemical manure or fertilizer composed of solid
ammonium hydrogen carbonate NHHCO, either alone or mixed with sulphate of
ammonia lime or other suitable material.
In carrying out the invention I employ the ammonium hydrogen carbonate either
in a crystalline or powdered or for horticultural purposes it may be dissolved in
water and applied in a liquid state.
When desired the ammonium hydrogen carbonate may be mixed in any desired
proportions with sulphate of ammonia, nitrate of soda, lime, or other material.
I am well aware that sulphate of ammonia has been largely manufactured for
the purpose of a manure but the carbonate of ammonia I find to be a much better

page_text: fertilizer than either the sulphate of ammonia or nitrate of soda now largely
employed for the purpose on account of its being :-
(a) Less soluble than either of these,
(b) More readily decomposed as required for plant life,
(c) More efficient, as the whole weight of the article is utilised as a plant food.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
A chemical manure or fertilizer composed of solid ammonium hydrogen
carbonate NH,HCO, either alone or mixed with other materials substantially as
described.
