Land, climate and agricultural enterprises vary considerably from one area of the state to another. To find solutions to problems in each area and to study the impacts of regional differences, the Iowa Agriculture Experiment Station puts researchers in the fields of research farms across Iowa. Farms near Ames are used for intensive studies and for teaching purposes.
More than 130 Iowa State faculty members use the College of Agriculture and Life Sciences’ farms for teaching, research and extension. A similar number of staff members are involved as project leaders and workers. Each year about 2,000 students receive hands-on education experiences at teaching farms, including a farm management course in which undergraduates manage a crop and livestock farm. About 15,000 people visit Iowa State’s Research and Demonstration Farms every year.
Iowa has about 20 major soil associations, or combinations of soil types. Soil types are repeated from field to field within a geographic region. Soil types may differ in topography, texture, drainage, acidity, content of organic matter and nutrients and susceptibility to erosion. These characteristics partly determine the farm enterprises and management practices most suitable and profitable in a particular area.
Average annual rainfall in Iowa ranges from less
than 26 inches in the northwest to more than 34
inches in the southeast. Annual mean temperatures
range from about 46 degrees in the northern tier
of counties to 52 degrees in the southern two tiers
of counties. There are about 40 more days of frost-free weather in southeast Iowa compared with
northeast Iowa.
Scientists assess the influence of soil differences and climate on agricultural practices by conducting similar experiments at several research farms. Projects at research farms often continue for many years to observe fluctuations in environmental conditions and long-term trends.
Markets and resources also vary across the
state. At research farms, researchers determine the
profitability of an agricultural enterprise in a given
area. The research also yields clues to the potential
of new crops and practices that may diversify the
agricultural base.
Local nonprofit associations of farmers and business people own or lease nine of the 14 research farms. The state owns the other five. In central Iowa, ISU affiliate organizations own land for research.
Associations and affiliates lease the research
farms to the Experiment Station. Income from farm
product sales is used to offset research costs. The
Experiment Station assumes the remaining costs of
operating the farms.
The Experiment Station also is active in partnerships with ISU Extension, USDA National
Resource and Conservation Service, USDA National
Soil Tilth Laboratory and several Iowa community
colleges.
Area producers suggest local problems that
need to be studied and often offer suggestions for
improving research at the farms. Producers make their suggestions as members of local advisory
committees. These committees meet at least once
each year with county and area extension staff
and ISU researchers. The committee members are
liaisons between the university and other producers.
The Experiment Station publishes research results in annual reports. Extension specialists use the reports in meetings, pamphlets, news stories, information websites and broadcasts. Local farmers can observe experiments firsthand and learn about the latest findings at field days that are held at the farms.
