Integrating Hunting And Grazing—A Southern Iowa Investigation Into Management Issues, James L. Pease, Dan Otto, John D. Lawrence Jan 2005

Integrating Hunting And Grazing—A Southern Iowa Investigation Into Management Issues, James L. Pease, Dan Otto, John D. Lawrence

Leopold Center Completed Grant Reports

If successful, land owners that want the habitat can rent the land to cattle producers (increasing access to pasture) without sacrificing their objective (good hunting), and cattle producers can provide good hunting without sacrificing their objective (good pastures). This dual purpose use for land can increase access income for both parties. The key is that the management of such lands must be timed carefully, and managed with both the birds and the cattle in mind. It takes more management skill, but it means the two can be compatible.

What is the potential payoff for farmers moving from traditional whole-field management or integrated crop management to precision farming? Using computer models, the investigators sought to analyze how inputs can be applied at optimal rates variably across a field in order to match inputs with crop needs. Over the long term, only modest increases were shown in gross returns from these practices. However, gross returns for individual years can be substantial.

Levels of fertilizer and pesticide usage in Iowa may change in response to at least two forces. One is growing public concern about the envi­ ronment, which has resulted in increased regu­ lation of the manufacture, distribution, and application of chemical pesticide products. Use of some products has been severely re­ stricted, while others are under evaluation.

Leopold Center Completed Grant Reports

Crop and livestock production are important economic components for many rural com­ munities. In 1992, Iowa led the nation in corn and hog production, and ranked second, third, seventh, and eighth, respectively in soybean, cattle and calves, poultry, and dairy cow pro­ duction. Livestock and livestock products generated over 64% of the state's total cash farm receipts during 1992—more than $6.5 billion sales at the farm level.

Strict grading standards require that fresh market apples be blemish-free. Consequently, Iowa orchardists are heavy users of synthetic chemical pesticides, typically making more than a dozen pesticide applications each growing season. The environmental and economic costs of this practice are high. Environmental contamination from spray drift and residues in surface and groundwater is an ever-present concern. This concern is critical in orchards located near populated areas. In addition, these pesticide applications represent direct costs to Iowa growers in the form of pesticide, labor, fuel, and equipment.

Soil erodes over six times faster from cultivated Iowa cropland than from pastureland, even though almost 12 percent more of the pastureland acres are classified as highly erodible than the cropland acres. Because of serious concern about excessive erosion of Iowa's topsoil, profitable alternatives to row-crop production are needed for soils like those found in much of southern Iowa.

Double cropping, a system in which more than one crop is produced per year in a land area, helps to increase food and feed production in the United States. But the impact of double cropping on production of biomass (crops grown to be converted to fuel) has not been evaluated. Such cropping systems have been successful in the eastern and southern United States. If they can be adapted to the relatively short growing season of the extremely large and agriculturally productive north-central region of the United States, biomass production potential can be greatly increased.
