The National Agricultural Statistics Service (NASS) is an agency within the United States Department of Agriculture (USDA). The agency's primary responsibility is to prepare official estimates of agriculture for the nation and for each state. There are 45 field offices that serve all 50 states. The Wisconsin State field office is the Wisconsin Agricultural Statistics Service, located in Madison, WI. Field offices collect, verify, and analyze data which are used to prepare statistical estimates. Farmers, ranchers, and agribusinesses are the grassroots source of information, collected through voluntary surveys conducted by each state office throughout the year. Survey data are collected and summarized at the state level to provide statistical indications. These indications are analyzed by statisticians in each state office who then make recommendations to the national headquarters in Washington, D.C. Statisticians in headquarters review the state recommendations and issue the state and national estimates to the public on scheduled dates throughout the year. About 300 national and 9,000 state reports are issued annually. Cooperative Agreements with State governments also permit preparation and publication of county-level estimates of crops and livestock for many states. In addition, many field offices conduct surveys for other government agencies and private organizations. Wisconsin Agricultural Statistics publishes several reports which are available by subscription. These reports include: A) Crop Weather B) Wisconsin Crop Weather is published weekly from April - November. Information included in this report is: crop progress and conditions, weekly temperatures, precipitation, and soil moisture data. C) Wisconsin Farm Reporter; D) Wisconsin Farm Reporter is published twice monthly and summarizes the major reports compiled by the Agricultural Statistics Service.
