SOIL TEST WITH FERTILIZERS FOR CORN. 



By Pliny Moore. 



*Cords. 



Average of all the nothing plots : hard corn, 36.3 bushels ; stover, 

 1609 pounds. There was no soft corn in this experiment. 



This test was on the sanae acre as last year ; a rather elevated 

 southern slope with very moderate pitch. The soil is a good medium 

 loam and previous to last year had been four years in grass without 

 manure. Yellow flint corn was selected ; ])lanted in hills, May 16th ; 

 stooked Sept. 20th, and husked Nov. 5th. The yield of the nothing 

 plots last year was quite variable ; this year it was comparatively 

 uniform and the average about 13 bushels less. Both in July and 

 August plot 13 was judged to be the best, followed closely by 10, 9, 

 and 5.
