The new website pulls together material on research, extension, and teaching as well as resource and reference items. The latter, in turn, leads to a wide selection of links ranging from other university weed science web pages to industry sources and professional societies.

Report 2003-07: Understanding USDA Corn and Soybean Production Forecasts: An Overview of Methods, Performance and Market Impacts (updated January 2004)
http://www.farmdoc.uiuc.edu/agmas/reports/index.html

The purpose of this report is to improve understanding of USDA crop forecasting methods, performance and market impact. A review of USDA's forecasting procedures and methodology confirmed the objectivity and consistency of the forecasting process over time. No changes in methodology occurred in 2003. Month-to-month changes in corn and soybean production forecasts from 1970 through 2003 indicated little difference in magnitude and direction of monthly changes over time. USDA production forecast errors were largest in August and smaller in subsequent forecasts. There appeared to be no trend in the size or direction of forecast errors over time.

On average, USDA corn production forecasts were more accurate than private market forecasts over 1970-2003, with the exception of August forecasts since the mid-1980s. Private market forecasts in soybeans were more accurate than USDA forecasts for August, regardless of the time period considered. As the growing season progresses the USDA's relative accuracy in soybeans improved. USDA corn production forecasts had the largest impact on corn futures prices in August and recent price reactions have been somewhat larger than historical reactions. For soybeans, the largest reactions in futures prices occurred in August and September, but recent reactions have been large in October. Overall, the analysis suggests the USDA performs reasonably well in generating crop production forecasts for corn and soybeans.

New Resource for Pork Producers on Influenza
Dr. Christopher W. Olsen, University of Wisconsin-Madison
http://www.porkscience.org/

The Pork Checkoff has developed a new fact sheet on influenza, titled INFLUENZA: People, Pigs and Public Health. This fact sheet addresses a variety of aspects of the influenza virus, including its zoonotic characteristics and safety on the farm for pork producers and employees. Because pigs are susceptible to both mammalian and avian influenza viruses, they can serve as an intermediary from birds to people. This fact sheet can be found by going to the website and once there following these steps: Producer/Public Health to Publications to Fact Sheets to Influenza: People, Pigs and Public Health.

The 2004 IFARM Premium Calculator
http://www.farmdoc.uiuc.edu/cropins/insurance/2004/premium_index_2004.asp

The 2004 IFARM Premium Calculator provides premiums for six products across a range of coverage levels for 12 Midwestern states. Prices and volatilities for revenue products will not be known for certain until the beginning of March. These factors will be updated periodically as more information becomes available.

The 2004 IFARM Crop Insurance Evaluator
http://www.farmdoc.uiuc.edu/cropins/evaluator/2004/index_2004_IL.asp

The Evaluator aids farmers in making sound crop insurance decisions by showing the risk reductions and costs associated with different multi-peril crop insurance products. Users of the Evaluator choose a crop and county. The Evaluator then presents tables and graphs showing the farmer-paid premiums, average payments, net costs, values-at-risk, and frequency of payouts of different insurance payments for an example farm in the chosen county. Tables are available for Illinois, Indiana, and Iowa.
