Online Tool Developed at ISU Helps Farmers Earn More, Waste Less
Posted 25 February
2010
A new, free, online tool to help farmers make better-informed
operational decisions has been developed by software experts at Iowa
State University.
The program -- I-FARM, found at i-farmtools.org, -- assists farmers,
bankers, extension and cooperative people, and anyone else interested
in finding out more about farm management, in understanding how to get
the most out the land at the least cost.
The software was developed by Ed van Ouwerkerk and draws on information
collected from various state, regional and national sources.
The I-FARM program allows farmers to input various aspects of their
operation along with the location of their farm. The computer software
then predicts and compares farming outcomes.
"This farming model gives you opportunities to calculate alternatives
and see the benefits of each," said van Ouwerkerk, a research associate
and software developer in the department of agricultural and biosystems
engineering at Iowa State University.
The program starts with the location of the farm. Using Google
Earth®, the farmer can locate his or her farm and highlight up to
20 fields that the farmer wants to evaluate.
The farmer then inputs the crops intended for the field, the rotation
cycle he or she will use, the types and amounts of fertilizer, the farm
equipment used, typical yield and many other factors.
The program then tells the farmer what his or her costs may be, the
labor required, amount of fuel needed, how much soil erosion he or she
can expect, the amount of nitrogen and other chemical emissions the
farm will produce, the amount of income (this function uses frequently
updated market prices) and the subsidy payments the farmer can expect
get from the latest farm bill.
The farmer can input one scenario with one set of inputs, and a second
scenario with different inputs and compare the two, according to van
Ouwerkerk.
The program is designed to help the farmer, and doesn't make any
choices for the producer.
"The program gives information, and lets the farmer make the choices,"
said van Ouwerkerk.
For instance, a farmer might discover his inputs will result in greater
soil erosion. The farmer can use the information to choose to plant
different crops.
"The software knows the slope of the land because it uses Google Earth.
If the farmer looks at the outcomes and sees that he is losing too much
soil, he may choose to change crops," said van Ouwerkerk. "Maybe he
shouldn't plant corn here, maybe he should plant a perennial, like
alfalfa."
The software also can help the producer with many aspects of the farm.
"This farming model gives you an opportunity to calculate alternatives
to different crop rotations and see the benefits of each," he said.
"That includes environmental benefits, ammonia release, erosion,
perennials instead of annuals, and if you have cover crops instead of
only annuals and different tillage practices."
The program should help farmers make smart choices about their
operations, said van Ouwerkerk.
"Farmers find their information about farming from a variety of sources
and often follow patterns because of habit," said van Ouwerkerk. "This
software will tell you what is scientifically right."
Van Ouwerkerk also thinks this tool will be valuable for extension
agents, bankers and anyone else who is interested in looking at farming
practices and profitability.
The program includes a short tutorial to help first-time users. Farmers
can go to the site and try it themselves, and if they have problems,
they can contact van Ouwerkerk at ISU (515) 294-4037 or John Lundvall
at ISU Iowa Learning Farm (515) 294-5429.
The project started as a program to cover three states - one that would
give farmers answers on converting their farms from crops-only
operations to crop-and-livestock operations. As the scope of the
project grew, van Ouwerkerk said more and more people got involved.
Because the project touches so many aspects of farming - production,
soil management, and fertilizer runoff - the project began to gain
interest from various organizations. In the end the project received
funding from the U.S. Department of Agriculture, the Department of
Energy, the National Science Foundation and the Leopold Center for
Sustainable Agriculture at Iowa State.
