OKLAHOMA CITY (AP) - Oklahoma Secretary of Agriculture Jim Reese is urging farmers to respond to the 2012 Census of Agriculture. Reese announced Tuesday that 70 percent of Oklahoma producers already have responded to the census, which is conducted every five years. He says those who have not completed the survey still will get one last mailing from the U.S. Department of Agriculture's National Agricultural Statistics Service. Reese says new data from the NASS shows total gross farm receipts exceeded $7.8 billion in Oklahoma for the first time in 2011, with $6.6 billion from livestock and $1.2 billion from crops. He says the data collected by federal officials is used by town planners, policy makers, agribusinesses and others to make key decisions for Oklahoma communities.
