Does anyone here know anything about agricultural subsidies in the US? I know a little, and only need to know a little more, but I'm hoping there's someone who can help with a few key pieces of information that I don't know and can't find quickly on the web.

I'm looking for a history of agricultural subsidies paid out, specifying products - mainly for 1995. All I can find is 2006 in detail and a total of what was paid out for other years.

Also, I'm wondering when the government announces the subsidies for the coming year. I know I read an article on changes in the subsidies when last year's came out, but I can't remember when I read it.
