Dec, 1927] fertilizer inspection, 1927 3 



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 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 New Hampshire, the 96 

 complet-e fertilizers analyzed in this year's inspection 

 would have been comprised of 9 grades. Instead, there 

 are 26 grades- This number should be reduced to 24 by 

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

 double strength of the grades 4-8-4 and 5-8-7. These 24 

 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 double strength grades equivalent to 

 5-8-7 and 4-8-4, there were 4 grades representing 15 brands 

 containing more potash than the agronomists of New Eng- 

 land consider is necessary or profitable to use. No grade 

 in the New England Standard Nine contains more than 

 7 per cent potash. Three grades, representing 14 brands, 

 were guaranteed to contain 10 per cent potash. One brand 

 was guaranteed to contain 8 per cent potash. In Table 

 1 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.
