34 BULLETIX 320, U. S. DEPARTMENT OF AGRICULTURE. 
The tillage practices with corn, which is the only intertilled crop, 
are very uniform. Practically all the corn land is broken in the 
spring with 3 or 4 horse sulky plows. The common practice of 
preparation is to roll the land just after plowing and to fellow the 
roller with a spring-tooth harrow. Then before planting, it is har- 
rowed again with a spike-tooth harrow. Practically all the corn is 
planted level and in checks 3| feet apart each way, alternating the 
hills with two and three grains. 
After the corn is up a few of the farmers use the spike-tooth har- 
row for the first working, but practically all the cultivating is done 
with a 2-horse 6-shovel cultivator, alternating the cultivations with 
the rows and across the rows with the checks. Usually five cultiva- 
tions are given. Both the white and yellow dent varieties of corn 
are grown. 
The most prevalent weeds are foxtail, pigweed, Canada thistle, 
ragweed, and curled dock. 
SURVEYS IN MAURY COUNTY, TENN. 
The tillage records (Table XVI) for Maury County, Term., were 
taken near Columbia. This section is rolling and in some parts 
extremely rough and rocky. Considerable quantities of phosphate 
rock are mined near Columbia, and limestone is plentiful. The 
Hagerstown loam, the predominating soil in this vicinity, is very 
productive. 
Most of the farms through the more prosperous sections are rather 
large, with extensive fields, and are generally operated by the owners 
with hired labor or tenants. The principal reads have been mac- 
adamized and the country generally is prosperous. 
Few farms have any set rotations, but a rotation of corn one 
year, oats one year, wheat one or two years, clover one year, and 
pasture one year is maintained to some extent. Very little fruit or 
truck is grown, and the principal sources of income are grain, hogs, 
and cattle. 
The extensive type of farming found here, together with the cheap 
labor available, is responsible for the irregular methods of corn culti- 
vation. Before planting, the land is usually harrowed twice with a 
disk harrow and once with a spike-tooth harrow. Most of the corn 
is planted level and in drills. 
After the corn is up it is usually harrowed with a spike-tooth har- 
row. After this, most of the cultivating is done with a 2-horse -i- 
shovel cultivator and a 1-horse spike-tooth cultivator. Usually 
four or five cultivations are given. Crimson clover and rye are fre- 
quently sown at the last cultivation as a cover crop. Both the yellow 
and white varieties of dent corn are grown.
