To give an illustration with one of the substances which is 

 absolutely essential for vegetable growth, I will take sulphuric 

 acid, the proportions of which in 1000 lbs. of our ordinary 

 crops are given in the last column of this table. Sulphuric 

 acid, in the form of some sulphate, must be present in the 

 soil. If we should remove all the sulphates from a given soil, 

 it would be totally impossible to grow any crop or any plant 

 there unless the sulphates were replaced. That is one of the 

 first principles of agricultural science, which applies equally 

 to all of the ingredients stated in the table, with the possible
