Effects Of Corn Crop Residue Grazing On Soil Physical Properties And Subsequent Soybean Production In A Corn-Soybean Crop Rotation (A Progress Report), Justin Clark, James R. Russell, Douglas Karlen, Darrell Busby, L. James Secor, Brian Peterson, Larry Pellack, Carroll Olsen, Shawn C. Shouse

The highest cost to beef cow-calf producers is the feeding of stored feeds in winter months. To lower feed costs, many producers will try to extend the grazing season into the winter. The primary resource for winter grazing in the Midwest is corn crop residues. On the average, corn crop residue grazing will reduce the amount of hay needed to maintain cows by approximately one-half ton per acre grazed over the winter. Although crop residue grazing is quite effective in reducing feed costs, some producers are concerned that corn residue grazing will have an adverse effect on soybean yields the …

Effects Of Corn Crop Residue Grazing On Soil Physical Properties And Subsequent Soybean Production In A Corn–Soybean Crop Rotation (A Progress Report), Justin Clark, James R.

Beginning in 1999, two locations in Iowa (Chariton, Atlantic) were used to study the effects of corn residue grazing by beef cows on soil characteristics and soybean yields the following growing season. Cows were allowed to graze inside selected paddocks at monthly periods throughout the fall and winter. For a grazed and ungrazed comparison, grazing exclosures were used inside the grazed paddocks, while one paddock was left ungrazed for a control. Also, the following year, equal portions of the fields went to no-tillage and disked soil prior to soybean planting so that effects of corn residue grazing on tillage treatments …

Winter Grazing Of Corn Residues: Effects On Soil Properties And Subsequent Crop Yields From A Corn-Soybean Crop Rotation, W. Darrell Busby, James R. Russell, Douglas L. Karlen, L. James Secor, Brian Peterson, Carroll Olson, Shawn C. Shouse, Dallas L. Maxwell

Corn residues could be a good resource for winter cattle grazing. The study investigates whether winter grazing causes soil compaction and yield reduction in crops that are planted following grazing.

For three years beginning in 1999, a 96-acre field near Atlantic, Iowa was used to study the effects of corn residue grazing by beef cows on soil characteristics and soybean yields in subsequent years. Each winter, cows were allowed to graze corn crop residues inside selected paddocks in four sub-fields over five monthly periods. To compare the effects of grazing, one paddock was left as an ungrazed control. At the end of grazing in the spring, soil bulk density, moisture content, and penetration resistance were measured inside and 15 ft outside twelve grazing exclosures in each paddock. Soil surface roughness, …

Tb181: 2000 Milk Processing Costs In Maine, Timothy J. Dalton, George K. Criner, John Halloran

George K. Criner

The objective of this study is to provide an estimate of the theoretically lowest achievable costs of processing and distributing milk in Maine. This processing and distribution margin (referred hence as "margin") is estimated for a state-of-the-art processing plant assumed to be located in the Portland, Maine, area. The plant is assumed to produce and distribute a line of products including white milk, chocolate milk, orange juice, and other fruit drinks, and to distribute additional purchased products such as cheeses and yogurts. This report will present information for four plants to better study the impact of plant size and production …

B853: Cost Of Producing Milk In Maine: Results From The 2010 Dairy Cost Of Production Survey, Richard Kersbergen, Gary Anderson, George Criner, Anthony Davis

George K. Criner

The present study reports on a survey conducted for the Maine Milk Commission to determine the cost of milk production for 2010. This assessment was undertaken sooner than the normal three-year update because of the difficult economic climate for dairy farms in Maine.

Tb204: Organic Milk Production In Maine: Attributes, Costs, And Returns, Amelia L. Cook, Patrick S. Heacock, George K. Criner, Lisa A. Bragg

George K. Criner

This report summarizes attributes, costs, and returns for organic dairy farms in Maine that responded to the 2008 dairy cost of production survey. This survey and analysis was conducted by the University of Maine in cooperation with the Maine Milk Commission. This publication reports on data collected over the 2007 production year. Analysis and discussion of the data revolve around four categories. The first category averages all 30 organic farms to create a statewide group. The authors then broke these 30 farms into three size groups (small, medium, and large) based on the number of cows on each farm. There …

Increasing The Value Of Wool In Wyoming And Beyond: The Impact Of Uw's Wool Lab And Library, David Kruger

David Delbert Kruger

At the turn of the twentieth century, little more than a decade after Wyoming attained statehood, a young agricultural student at the University of Wyoming saw a pressing need to improve the quality and reputation of Wyoming wool. When John Arthur Hill became a professor in 1907, the Wool Department he created would go on to not only assist Wyoming sheep ranchers in wool production, but provide the sheep industry with a better understanding of how wool fleeces and fibers could be improved across the nation. Under Hill’s leadership and his later protege Robert Homer Burns, the Wool Department developed …

Jcpenney And His Agrarian Animals: The Award-Winning Livestock Of A Department Store Icon, David Kruger

David Delbert Kruger

Widely known for his department store chain, James Cash Penney (1875-1971) greatly contributed to American agriculture through his horse and cattle breeding enterprises. Beginning in 1917, three years after moving to New York City, Penney began using his personal capital to acquire, breed, and sell outstanding animals for agricultural purposes. By the 1920s, his Guernsey dairy herd had earned a worldwide reputation for quality and production, with herd sire Foremost eventually becoming the namesake for one of the largest dairy cooperatives in the United States. By the 1940s, Penney was personally developing award-winning beef cattle herds on the Missouri farm …

Jcpenney As Cattleman, David Kruger

David Delbert Kruger

Though widely known for his department store chain and its Wyoming origins, James Cash Penney also played a prominent role as a cattleman from the 1920s until his death in 1971. This presentation will explore Penney's personal and professional involvement in the cattle industry, including his significant contributions within the Angus, Hereford, and Guernsey breeds.
