38 FORAGE OROPS 
seeding, as well as time of harvesting, varies 
greatly, the dates are of course only approximate. 
In order that the land may be covered in winter, 
rye or wheat is seeded when the last crop is 
removed. To accomplish this in the case of Nos. 
4,5 and 6, rye is seeded with the barley or barley- 
and-peas, and it will usually grow sufficiently, 
after the forage is removed, to make a good cover 
for the winter. 
It will be observed that in the rotations in the 
latter table, alfalfa is not included, although a 
small area was used in the rotation indicated in 
the previous table. Where it is possible to grow 
alfalfa, it would be quite unnecessary to use so 
large a number of crops. In fact, rye, crimson 
clover, alfalfa and corn would serve to provide 
practically a continuous supply of food, as the 
alfalfa will be ready for harvesting usually the 
fourth week in May, and the cutting can be so 
arranged afterward as practically to provide a 
continuous supply of forage until the middle of 
September. Alfalfa is one of the cheapest and most 
satisfactory crops that can be grown for soiling. 
THE ROTATIONS MUST BE CAREFULLY PLANNED 
It will be observed from a study of the tables 
of rotations that, in order to provide for a con- 
tinuous supply of forage crops, careful plans must
