BARNYARD, STABLE, GREEN MANURES 109 



The manure in this case was applied twice in the rotation; 6, 8 and 10 

 tons per acre to the corn, the same amounts to the wheat and none to either 

 the oats or grass. 



The returns per ton of manure are based on a valuation of crops 

 as follows: Corn 50 cents a bushel, oats 32 cents a bushel, wheat 80 cents 

 a bushel, hay $10 a ton, and oat straw, wheat straw and corn stover $2.50 

 per ton. 



A similar experiment at the Ohio Experiment Station covering a 

 period of eighteen years has ' also shown the largest return per ton of 

 manure in case of the smaller applications. The results are given in the 

 folio wins; table: 



Value of Manure. Average 18 Years. 

 Rotation: Corn,* Oats, Wheat,* Clover, Timothy (Five-year Rotation). 



Rotation: Potatoes, Wheat, f Clover (Three Years). 



Methods of Applying Manure. — A uniform rate and even distribution 

 of manure are essential. This can be most economically effected by the 

 use of a manure spreader. It does the work better than it can be done 

 with a fork, and at a great saving of labor. While a manure spreader is 

 rather an expensive implement, it will be a paying investment on any 

 farm where 60 tons or more of manure are to be applied annually. It is 

 a common practice in most parts of the country to apply manure to a 

 grass sod and plow it under. In many cases manure is also applied to 

 corn land and land that has been in small grain, to be followed by other 

 or similar crops. While it is the consensus of opinion that the manure 

 applied in this way will give best results, there is some question as to 

 whether or not more of it should not be applied in the form of a top 

 dressing.

* Manure applied to thes~ crops only. 



t Manure applied to wheat, except in second 8 tons application, which went on potatoes.
