A study conducted by University of Illinois agricultural economists evaluated subsequent acreage changes across crops to better understand which crops have been most profitable during a period when farm legislation contains few acreage constraints.
"Since the passing of the Freedom to Farm Act, soybean and corn acreages have increased significantly," said U of I agricultural economist Gary Schnitkey. "Crops losing acres include wheat, barley, grain sorghum, corn silage, cotton, peanuts, dry edible beans, and potatoes."
To evaluate acreage changes, data detailing annually harvested crop acres in the United States was obtained from the National Agricultural Statistical Service, an agency of the U.S. Department of Agriculture. Data was collected for all crops with over 1 million acres harvested in 2008. There were 13 crops identified, including soybeans, corn for grain, hay, rice, wheat, barley, grain sorghum, corn for silage, cotton, peanuts, dry edible beans, potatoes, and sugar beets.
For the study, harvested crop acres were averaged for 1990 through 1994, the years preceding the Freedom to Farm Act, and for 2005 through 2009, following the passing of the legislation.
"From the early 1990s to the late 2000s, soybeans were identified as the crop with the largest acreage increase," Schnitkey said.
Soybeans averaged 58.2 million acres harvested per year from 1990 to 1994, increasing to an average of 72.2 million acres from 2005 to 2009. This 14.0 million acre increase represents a 24 percent expansion in soybean acres.
"Corn also had a sizable increase of 9.4 million acres, or a 14 percent expansion in corn acres," he said.
Soybean and corn acreage growth was concentrated in the Great Plains and the greater Corn Belt. North Dakota had the greatest combined acreage change with a 4.2 million acre increase in its soybean and corn acres. U.S. states with a 2 million acre or greater increase in soybean and corn acreage include Minnesota, Kansas, Nebraska, and South Dakota. States with a 1 to 2 million acre increase include Iowa, Missouri, Illinois, and Wisconsin. States with between a 0.4 and 1 million acre increase include Michigan and Ohio.
According to Schnitkey, two of the 13 crops have kept relatively stable in their acreage. These include hay, averaging about 60 million acres, and rice, averaging about 3 million acres. The remaining nine crops had sizable acreage reductions.
"Wheat had the largest reduction in acreage following the passing of the Freedom to Farm Act, dropping from 62.8 million to 50.7 million acres," Schnitkey said. "This 12.1 million acre decrease represents a 19 percent decline in wheat harvested.
Other crops losing 1 million acres or more are barley with minus 4.0 million acres, grain sorghum with minus 3.7 million acres, corn for silage with minus 3.7 million acres, and cotton with minus 1.9 million acres.
"For states with large soybean and corn acreage increases, the crops losing acres did not balance out these gains," Schnitkey said. "In Illinois, for example, acreage changes in the 13 crops resulted in a positive 0.3 million acres. This means that 0.3 million acres came from some other source, most likely pasture acres.
"A number of reasons could be given for the large gains in U.S. soybean and corn acres. On the supply side, these crops have had larger yield increases and a greater number of biotechnology varieties and hybrids offered than other crops. On the demand side, new uses for soybeans and corn account for some of the acreage changes, with biofuels being a major new use of corn."

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
