COVER CROPS 793 



COMBINATIONS OF COYKR CROPS 



N"o one crop meets nil the requirements of an ideal cover crop; 

 for this reason it is always best to use a combination. The 

 nature of the combination will depend on the soil and the season. 

 It should be so planned as to give quick growth, a maximum 

 amount of organic matter, winter protection, and preferably 

 should contain some legume, except in orchards already making 

 too vigorous growth. In the table below are given a few good 

 mixtures.
