WHAT MANURES TO APPLY.

Ag. Soc., p. 335,1869: "After much experience, I think ma- 

 nuring grass lands is one of the worst subjects to treat. I have 

 seen bones applied and produce no good whatever; and on the 

 other hand, I have seen them used with immense advantage. I 

 have seen guano produce a splendid crop, while the year follow-' 

 ing the crop has been worse than before guano was applied. It 

 is impossible to give any definite rules without knowing the 

 kind of land to be manured, and other attendant circumstances. 

 Still money judiciously laid out in the improvement of grass 

 land brings in a more certain return than where expended in the 

 growth of wheat." 



In 1864 Dr. R. C. Kedzie, of Michigan Agricultural College, 

 made some experiments in top dressing the first year after seed- 

 ing to Timothy and clover with oats. The dressing was applied 

 from the 5th to the 10th of May on a soil of sandy loam of mod- 

 erate fertility.
