"Broken down by regions, costs were lower in southern Illinois,
primarily because of lower land costs," said Dale Lattz, U of I
Extension farm management specialist who prepared "Cost to
Produce Corn and Soybeans in Illinois -- 2006," a
report available online at Extension's Farmdoc site.
total of all economic costs per bushel in the different sections
of the state ranged from $2.74 to $3.11 for corn and from $6.94
to $7.30 for soybeans," Lattz said. "Variations in this cost
were related to weather, yields and land quality."
The report was prepared with data provided by the Illinois
Farm Business Farm Management Association, which consists of
5,800-plus farmers and 60 professional field staff. The state is
divided into four regions for the study: northern, central with
"high" soil ratings, central with "low" soil ratings and
"The sample farms had no livestock and had more than 500
acres of productive and nearly level soils in each area of the
state," said Lattz.
In 2006, the total of all economic costs per acre for growing
corn in Illinois averaged $502 in the northern section, $500 in
the central "high" section, $472 in the central "low" section
and $448 in southern Illinois. Soybean costs per acre were $387,
$386, $361 and $341, respectively.
"Costs per bushel of corn in 2006 as compared to 2005 were
lower for all geographic areas of the state except the southern
region," said Lattz. "Costs per bushel were lower due to higher
"The average corn yield in 2006 was 38 bushels per acre
higher in northern Illinois than in 2005, 20 to 25 bushels
higher in central Illinois and six bushels per acre higher in

However, costs per acre were higher in all of the different
geographic sections compared to 2005.
"Across the state, total costs per acre to produce corn increased
5 to 8 percent," said Lattz. "A number of costs increased, including
fertilizer, seed, fuel, insurance and land costs.
"The non-land interest cost per acre increased the most, due to
higher interest rates and higher grain inventory values."
Production costs per bushel of soybeans in 2006 increased in all
areas of the state except for the northern region as compared to
"Costs per bushel for soybeans increased mainly due to higher
per-acre costs," he explained. "Soybean yields were the same or
slightly higher than the year before except for the southern region.
Soybean yields ranged from one bushel per acre lower to four bushels
per acre higher in 2006 as compared to 2005.
"Increases in costs per bushel ranged from 12 cents in central
Illinois with the lower rated soils to 71 cents in southern
Illinois. Costs per bushel were 5 cents less in northern Illinois."
Like corn, total costs per acre to produce soybeans increased in
all geographic regions of the state compared to 2005. Costs
increased $27 per acre in northern Illinois, $19 per acre in central
"high" soils, $20 per acre in central "low" soils and $28 per acre
in southern Illinois.
"Fertilizer, fuel and interest were some of the costs that
increased," said Lattz. "Average soybean yields in the different
areas ranged from one to six bushels per acre higher than the
four-year average from 2003 to 2006."
