SUMMARY OF GRASS AND LEGUME SILAGE SURVEY 



Operations 



Method of Preservation 



The following number of operators report using the z^arious methods 

 of preservation: 



Molasses 328 A. I. V. 3 



Phosphoric Acid 34 No Preservative 15 



Preservative used per ton of green material 



Where molasses grass silage was preserved the rate of application varied 

 from 14 pounds to 250 pounds per ton. The weighted average for the various 

 types of materials ranged from 45 to 75 pounds as is shown in the following 

 table : 



Operators Reporting Molasses Applied on Some of the Green Crops 



The range in price paid for this molasses was .8^ to 3.0^ per pound 

 with an average price of 1.2^. Several of the operators realized that the 

 lower amounts of molasses applied were not sufficient for proper preserva- 

 tion. Fifty-three of them advised the use of plenty of preservative. 



The 34 operators reporting phosphoric acid silage used from 3^ to 20 

 pounds of phosphoric acid per ton. The average cost of this acid was 5>4fJ 

 per pound. 



U^as the preservative diluted with tvater? 



One hundred sixty operators using molasses reported that it was diluted 

 with water, while 164 reported no dilution. Sixteen operators using phos- 

 phoric acid diluted it with water while 13 reported no dilution. 



Hoiv inucJi wafer was added per ton of green material f 



The rate of dilution in both molasses and phosphoric acid silage showed 

 that dilutions were made up to 60 gallons of water per ton of green material 

 in each group. Twenty-three advised the addition of water to inaterial that
