The results of this experiment show that phosphoric acid was the 

 most useful of the single ingredients. It caused the greatest average 

 and the greatest absolute increase in the crop ; and, though the result 

 of its use either singly or in combination is invariably a money loss, 

 this loss is upon the average small, and if the phosphoric acid, doubt- 

 less remaining in the soil is taken into account the result will be a 

 gain. It is judged that this gain might have been made absolute 

 "with complete fertilizer " by using a very small proportion of 

 nitrate and potash. 



Here (the same is true of all the experiments and the statement 

 will not be repeated) as in the Yarmouth experiment it is noticeable
