TABLE SHOWING NITROGEN CONTENT OF FERTILIZERS.
Nitrate of soda Sulphate of ammonia Nitrate of limp Cyanamide (variable) Nitrate of ammonia Urea 95 per cent ...
Per Cent Nitrogen.
15 21 13 17-21 35 45 In estimating the values of fertilizers it is customary to speak of the cost per unit. Let me explain briefly what is meant by this.
* This objection has now been overcome. The material now made is in excellent con dition for distribution. Waterproofed sascks are now sometimes employed. F. H. 1921....
10 If you look at the table you will see the proportion of nitrogen which is present in the various substances with which we have been 'dealing. Now, under ordinary conditions a ton of nitrate of soda was worth L. E. 10 ; it contains fifteen per cent of nitrogen. Divide L. E. 10 by 15 and we get the cost of one per cent of nitrogen in a ton of material. This is what is called the price per unit. Now, if the nitrogen in all these various fertilizers may be assumed to be of equal value, it is easy to compare the price of nitrate and so determine the value of the manure in question.
