$this->bbcode_second_pass_quote('', 'P')retty soon farmers will start growing corn on top of corn (vs beans) and then yields should? probably drop from year to year.
Some farmers already practice a corn-corn-bean rotation instead of the corn-bean rotation. According to an Iowa State University study (see above link) corn yields drop 12% in the second year of a corn-corn-bean rotation. Since corn yields almost 4 times as many bushels as soybean that 12% loss is more than made up.
6 years c-c-b
150 bushels + 132 + 40 + 150 + 132 + 40 = 644 bushel
6 year c-b
150 +40+150+40+150 +40 = 570 bushels
There is much more than total bushel output that goes into the decision to go to a c-c-b rotations than just total bushel output-otherwise everyone would already be doing.

The U.S. corn crop is forecast at 10.7 bln bu, down 1% from October and 3% lower than last year.
Did you read the whole USDA report?
$this->bbcode_second_pass_quote('', 'C')orn production is forecast at 10.7 billion bushels, down 1 percent
from October and 3 percent lower than 2005. Based on conditions as
of November 1,
yields are expected to average 151.2 bushels per
acre, down 2.3 bushels from October but
3.3 bushels higher than
last year. If realized, the yield would be the second largest on
record, behind 2004. Yield forecasts are lower than last month
across much of the western and central Corn Belt and Atlantic Coast
States as producers reported that actual harvest yields were not as
good as expected earlier due to lower grain weight per ear. Stalk
quality and lodging problems were also reported in some areas.
Producers in the northern Great Plains, Delta States, and parts of
the Southeast reported better than expected yields. Compared with
last year, yields are higher in all Corn Belt States, except Iowa
and Minnesota.
Soybean production is forecast at 3.20 billion bushels, up
slightly from October and
5 percent above 2005. If realized, this
would be the
largest U.S. soybean crop on record. Based on
November 1 conditions,
yields are expected to average 43.0 bushels
per acre, up 0.2 bushel from October and
equal to last year's
record high yield. Producers in the northern Great Lakes States,
Delaware, New York, North Carolina, and the Dakotas are realizing
higher yields than expected last month, while yield prospects
decreased slightly as harvest progressed in Illinois, Kentucky,
Missouri, and Pennsylvania.
Area for harvest in the U.S. is
forecast at 74.5 million acres, unchanged from last month but
up
5 percent from 2005.
Yields were great this year-second highest on record for corn. Just wasn't enough planted.
