On the other hand it does make sense that the 2,800 tons is only from dairy farms. That one farm produces one ton of waste (he said 2,000 lbs.)

I found this: http://www.mpnnow.com/news/x256222366/Number-of-farms-in-New-York-drop

Figures collected by the New York Field Office of the U.S. Department of Agriculture show there were 36,300 farms on 7 million acres last year, a drop from 36,600 farms on 7.1 million acres in 2009.

Statistics for dairy farms alone was alarming, as well.

The state lost 23 percent of its dairy farms in five years, from 2001 to 2007. In 2007, the state had nearly 5,700 dairy farms , down from nearly 7,400 in 2002, according to the USDA.
