PLOWING UNDER GREEN MANURE 91 



plowing under green clover is to accomplish is defeated 

 unless it is thoroughly covered when plowing. 



The principal reason why farmers mow green crops 

 before plowing them under is because of their inability 

 to successfully cover them with the plow. With the advent 

 of the combined rolling coulter and jointer this difficulty 

 is overcome. This attachment on a plow will turn 

 under the rankest growth of green vegetation more 

 efficiently than dry vegetation can be turned under in 

 the ordinary manner.
