5. 4-8-4 — For potatoes, beets, carrots, onions and other 

 root crops on the heavier soils. 



6. 4-8-6 — For potatoes and other root crops on loams. 



7. 5-4-5 — For tobacco. 



8. 5-8-7 — For potatoes, celery and other truck crops on 

 light soils. 



9. 8-6-6 — For top dressing hay and pasture land. 



One object of this conference w^as to decrease the need- 

 lessly large number of different grades on the market. Had 

 the recommendations made been accepted by the consumers 

 of fertilizer materials in New^ Hampshire the 87 complete 

 fertilizers analyzed in this year's inspection would have been 

 comprised of 9 grades. Instead, there are 31 grades. This 

 number might be reduced to 29 by omitting tw^o grades, 

 8-16-8 and 10-16-14 which are double strength respectively 

 of the grades 4-8-4 and 5-8-7. These 29 grades include 

 only 6 of the New England Standard Nine. Three grades 

 of the New England Standard Nine were not found offered 

 for sale. 



Not including the two double strength grades there were 

 7 grades representing 19 brands containing 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. Five 

 grades, not including the two double strength grades, repre- 

 senting 17 brands, 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.
