One object of this conference was to decrease the need- 

 lessly large number of different grades on the market. 

 Had the recommendations made been accepted by the con- 

 sumers of fertilizer materials in Ncav Hampshire the 81 

 complete fertilizers analyzed in this year's inspection 

 would have been comprised of 9 grades. Instead, there 

 are 25 grades. This number might be reduced to 23 by 

 omitting two grades, 8-16-20 and 10-16-14 which are 

 double strength respectively of the grades 4-8-10 and 

 5-8-7. These 25 grades include only 5 of the New Eng- 

 land Standard Nine. Four grades of the New England 

 Standard Nine were not found offered for sale. 



Not including the double strength grade equivalent to 

 5-8-7 there were 6 grades representing 15 brands contain- 

 ing more potash than the agronomists of New England 

 consider is necessary or profitable to use. No grade in 

 the New England Standard Nine contains more than 7 

 per cent potash. Six grades, representing 15 brands, 

 Avere guaranteed to contain 10 per cent potash. In Table 

 I are given the grades of complete fertilizers collected, 

 the number of brands found in each grade, the average 

 analysis of each grade and the average retail price per 

 ton.
