Table No. 4.— Potatoes. Effect of fertilizers. 



227 



The following table is compiled exclusively from American analyses. In 

 the first column is stated the total number of analyses from which the aver- 

 age was obtained. The probable accuracy of the average increases with the 

 number of analyses on which it is based. 



As it is desirable to know within what limits the composition of the roots 

 is likely to vary, the maximum and minimum amounts of each ingredient 

 have also been inserted in the table. 



It is placed here because of its value for reference in the study of the root 

 crops especially.
