The dairy farms vary considerably in size, some having less than 
30 acres in crops, and others having over 150. In general the larger 
farms have more cows; but, as shown in Table 6, there are wide 
mi riat ions in the number of cows kept on farms of about the same 
size.

As shown in Table 6, the smaller farms in general have more cows 
relative to their crop area than have the larger farms. This relation 
is shown more clearly in Table 7, which shows the average number 
of crop acres per cow for the more important groups in this classi- 
fication.

The number of crop acres per cow varies from 1.9 acres to 11.9. 
Most farms have between 2V^ and 6 acres. With this wide range in 
the intensity of stocking with cows there are corresponding differ- 
ences in the cropping system. The extent to which these differences 
in the intensity of stocking are accompanied by differences in the 
cropping systems is shown in Table 8. Only the proportion of the 
land in each group of crops is shown, as the differences in the size 
of the farms would make it difficult to compare the actual acreages 
for the different groups.
