NITROGEN 
at its best 
Nitrogen is at its best when combined with lime! This 
fact has been known for many years. In the case of 
‘Aero’ Cyanamid, there is the high concentration of 
20.6 per cent nitrogen and 70 per cent lime, An abun- 
dance of nitrogen for plant growth, and a lime residue, 
maintain the calcium balance in your soil. 
Then, too, when you use GRANULAR ‘AERO’ CYANA- 
MID there is the additional feature of even and easy 
distribution, to be had only in a dry, granular material. 
While war conditions greatly curtailed available 
supplies of ‘AERO’ CYANAMID, if is now gradually 
returning to the field of agriculture. 
So—keep in touch with the source of supply from which 
you have always obtained your requirements of ‘AERO’ 
CYANAMID—Agriculture’s most useful form of nitrogen.
