I don't recall how many years ago I got my first NASS report to file, but it was over 10 years ago, maybe even 15 yrs. I sent back the report each time, this year I did not get one to file.
Another point, in the past I've encouraged every producer to file their report, it seems a majority refused because they were afraid the info would come back to bite them (my feeling is they didn't report the sales)
This type of information is hard to get farmers to report because they don't trust the laws that force the info to just be used for statistics. For this reason I question how accurate any of this info can be, how can those who compile the info collected and "correct" it to get a final report.
