CoRN vs. FERTILIZER. 
For this presentation we have the record of the same plats planted 
with corn during four years, and the yield corrected to a full stand 
of four plants to a hill, as recorded in past reports. The corrected 
yield of ear corn, from the tenth acre plats, for the various years, 
was as below:—
