CEAP Cropland Farmer Surveys
In support of the Conservation Effects Assessment Project (CEAP) the National Agricultural Statistics Service (NASS) is conducting surveys with a randomly selected set of farmers nationwide. NASS interviews cooperating farmers to obtain current information on farming practices (e.g., crops grown, tillage practices, nutrient and pesticide application, conservation practices) at National Resources Inventory (NRI) statistical sample points. This farmer survey data is used in field-level physical-process models to assess the effects of conservation practices on cropland.

Farmer participation is voluntary, and the proprietary information gathered is kept in strictest confidence. The U.S. Department of Agriculture thanks all participants for their investment of time in cooperation with the farmer survey. You have made an important investment in the science of soil and water conservation and in the future of the Nation's conservation effort.
New: Second NRI-CEAP Cropland National Assessment Survey (CEAP-2), in 2015 and 2016
From October 2015 through February 2016 (and again in those months in 2016-2017), enumerators from the National Association of State Departments of Agriculture (NASDA) will survey about 23,500 U.S. farmers to obtain field data for the second NRI-CEAP survey. Data will be collected on conservation practices, CRP, cropping and tillage, pesticide applications, livestock manure applications, irrigation, field operations, size of operation, and more to help assess changes that have occurred since the first NRI-CEAP Cropland National Assessment (CEAP-1, in 2003-2006). CEAP-2 is designed to provide an evaluation of the trends in and effects of management and conservation practices put in place since CEAP-1. CEAP-2 follows the same design used in CEAP-1 except that the CEAP-2 surveys include both cropland and pasture acres. The information gathered will be used for performance reporting and policymaking and will influence conservation planning, program development, and practice implementation, thus enhancing the benefits of voluntary conservation.

2013 NRI-CEAP Survey of Farming and Conservation Practices in the California Bay-Delta Watershed Area
NRCS is partnering with USDA-NASS to deliver the 2013 NRI-CEAP survey, which collects information from agricultural producers in the California Bay-Delta watershed area, with a primary focus on the Sacramento River Watershed, the San Joaquin River Watershed, and the Tulare Lake Basin Watershed, about farming and conservation practices on cultivated and non-cultivated cropland. NASS representatives will visit nearly 1,764 farms in California and Oregon between September 2013 and February 2014 to collect information on farm production practices; chemical, fertilizer and manure applications; integrated pest management; and installed conservation practices.

2012 NRI-CEAP Re-survey of Farming and Conservation Practices in the Des Moines River and Western Lake Erie Basins
In 2012, NRCS partnered with USDA-NASS to obtain revised NRI-CEAP survey data in order to develop an updated assessment of the environmental effects of conservation programs and practices implemented within the Des Moines River (Iowa) and Western Lake Erie Basins. Since the CEAP survey was last conducted in the region, farmers may have adopted many agricultural best management practices using publicly available technical and financial assistance from conservation programs and through their own initiative and at their own expense. This survey will also capture all of those on-farm conservation accomplishments. NASS representatives visited more than 2,400 farms throughout Iowa, Indiana, Ohio, Michigan and Minnesota from November 2012 through January 2013. Producers provided information on farm production practices; chemical, fertilizer and manure applications; integrated pest management; and adopted conservation practices. As with all NASS surveys, respondents are guaranteed by law that their individual information is kept confidential.

2011 NRI-CEAP Re-survey of Farming and Conservation Practices in the Chesapeake Bay Watershed
NRCS partnered with USDA-NASS to obtain revised NRI-CEAP survey data in order to develop an updated assessment of the environmental effects of conservation programs and practices implemented within the Chesapeake Bay Watershed. NASS conducted a survey of approximately 1,500 farmers within the Chesapeake Bay Watershed from November 2011 through February 2012. This survey will provide farm-field level land management and conservation practice data for cropland fields associated with selected NRI sample sites throughout the region. The NRI-CEAP survey data will provide needed input into existing physical process models which assess water quality, soil quality, and associated resource concerns and document the environmental effects of conservation practices implemented within the watershed.
