Concept Caching: Soybean Agriculture in Presho, South Dakota

From our Concept Caching image cache that hopes to promote student spatial awareness by relating specific features on the Earth’s surface with their visual character and GPS coordinates. Through the site photographs and GPS coordinates demonstrate core concepts in geography.  Images are “cached” for viewing by core concept and by region.  Images are certainly useful for introducing visual content to students in all  Geography classes.

Soybeans growing in the semiarid ranchlands of western South Dakota.

This image submitted by Erin Fouberg provides a visualization of the scale and landscapes of crop agriculture in the United States.  The companion image description offers insight into this landscape and details over the two types of crop agriculture in this region.  It is also an interesting visual companion to some of the issues raised in the post, “Geographies of Green Diets.”

“Driving across the semiarid ranchlands of western South Dakota, I noticed the presence of a crop in the landscape that was recently found only in the eastern, moister region of the state: soybeans.

I called a colleague who works in agriculture at South Dakota State University to ask, “When did the cattle ranchers of western South Dakota start growing soybeans?” He replied, “When the soy biodiesel plants started popping up in Nebraska and Kansas and when genetically modified soybeans made it possible to grow the crop here.” He explained the development of Roundup Ready soybeans, a particular genetically modified soybean that can grow in more arid regions of the country. First, you plant the soybean; then you use an airplane to spray Roundup, a common weed killer that is manufactured by the company that produces the Roundup Ready soybeans, over the field. The application of Roundup over the entire field saves a lot of time and energy for the farmers because the genetically modified soybeans are resistant to the Roundup, but the weeds are killed. Monsanto, the company that produces Roundup, has developed soybeans, corn, cotton, and other crops that are resistant to Roundup.

Counter to the genetically modified Roundup Ready crops, organic agriculture —the production of crops without the use of synthetic or industrially produced pesticides and fertilizers—is also on the rise in North America. In wealthier parts of the world, the demand for organic products has risen exponentially in recent years. Sales of organic food in the United States, for example, went from under $200 million in 1980 to $1.5 billion by the early 1990s to over $10 billion by 2003 and $17.8 billion in 2007. Organic foods are now about 3 percent of all food sales in the country. The growth rate is so strong that some predict organic sales will approach 10 percent of total U.S. food sales within a decade. Parts of western Europe are already approaching that figure—notably Denmark, Sweden, Finland, and parts of Germany.”
