REASONS FOR GROWING SOY BEANS. 



Dairying is now the most important farm industry of the 

 state, and is likely to continue as such. Our farmers produce 

 very little of the grain which they feed to their dairy cows, — 

 their feed bills are therefore very large. The most logical way 

 to cut down these feed bills is not to raise more grain but to raise 

 more leguminous forage crops which will take the place of a part 

 of the grain in the ration of the dairy cow. These crops can be 

 more economically grown here than grain. 



Besides furnishing protein for the farm animals, legumes 

 enrich the soil and add to the farm fertility because of their
