What reading level is The Utility of Sulphate of Ammonia in Agriculture book?
To quickly assess the difficulty of the text, read a short excerpt:
Hydrogen 6-06 Sulphur 24-24 Oxygen 48-48 As it is usually sold, sulphate of ammonia of good quality is of from 95 to 97 per cent, purity that is, 95 to 97 per cent, is actual sulphate of ammonia; the remainder con- sisting chiefly of moisture, with any earthy or other im- purity that may have become accidentally mixed with it. Such manure will contain from 20*15 to 20^57 per cent, of nitrogen.
For trade purposes, nitrogenous manures are usually described as containing, a certain percentage of a...mmonia, though in many cases their nitrogen is not in that form. This is merely a conventional way of expressing the amount of nitrogen present. It has been said that there are four- teen parts of nitrogen by weight in ammonia and three of hydrogen. Therefore fourteen- seventeenths of the weight of ammonia consists of nitrogen. Similarly, if a manure contains 14 per cent, of nitrogen, it will be described as having 17 per cent, of ammonia.
In the case of sulphate of ammonia, therefore, containing 2O'5 per cent, of nitrogen, the amount of ammonia equiva- lent to this will be 20-5 X ^, or almost exactly 24-9 per H cent.
