In 1881 a second retort house was built and in 1885 an ammonium sulphate plant.
Between now and 1966 there will be no alternative supply of this ammonium sulphate nitrate, which is a vital chemical in the modern use of nitrogenous fertiliser.
Two hundred and fifty pounds or so of ammonium sulphate contain the necessary nitrates to make up for that taken out by a ton of wheat.
This will raise the cost of ammonium sulphate nitrate.
These two trace elements and ammonium sulphate are vital to the industry concerned.
In these highly concentrated fertilisers, it is vital to have ammonium sulphate nitrate.
Secondly, the allegation that the ammonium sulphate is being sold here at dumped prices may very well be true.
The obvious example is chemicals, and particularly potassium carbonate, sodium chlorate and ammonium sulphate, which we need, as do our allies.
