76 THE AMERICAN APPLE ORCHARD 



Buckwheat is by far the best of all the non-legumi- 

 nous cover crops, and is worthy of consideration under 

 any circumstances. It is best suited to northern and 

 northeastern states. Its great advantage lies in the 

 fact that it will germinate and give a good strong cover 

 no matter how late it may be sown. It also leaves the 

 land in good physical condition, which is a matter of 

 large importance. 



Rye, barley and oats are occasionally used sepa- 

 rately as cover crops, but are not to be recommended. 

 Rye may be used as a last resort, but oats should never 

 be sown among fruit trees.
