Capacity of Silos.

increases. A silo 36 feet deep will store nearly 5 times the 

 amount of feed that one 12 feet deep will. 



Doubling the diameter of a silo increases its capacity 

 more than fourfold and a silo 30 feet in diameter will hold 

 more than 9 times as much as one 10 feet in diameter and 

 of the same depth. It is clear from this that small silos 

 must be relatively more costly that those of larger diameter.

 well matured corn silage, in tons. 



In this table the horizontal lines give the number of tons 

 of silage held by a silo having the depth given at the left 

 of the column. 



527. Horizontal Feeding Area. In the construction of 

 silos it is very important to have the horizontal dimensions 

 such that the rate of feeding shall be rapid enough not to 

 permit moulding to occur on the exposed or feeding sur- 

 face. It is also important to have the horizontal dimensions 

 as large as possible because the larger the silo is the less it 

 costs in proportion to the feed It stores. Then, too, narrow, 

 small silos do not allow the silage to settle as well, and hence 

 in them the necessary losses are proportionally greater 

 than in the larger ones.
