However, I also read an article [3] that seems to indicate that the complete opposite was true as farmers who use BLM land have to maintain it which made public land cost $1.20 more than private (2011). However, I don't really trust this that much as the guy who wrote it was a farmer and on the "Public Lands Council" which is a pro ranching organization. [4]

(I didn't spent a lot of time researching but I found those articles interesting so hopefully you will as well!)
Are you contending that most beef interacts with BLM properties in some fashion?
The third link is just a counter argument to that says although the land looks cheap in reality its more expensive because of land maintenance.
However, I don't trust that article a lot as it was written by a rancher that is in a pro ranching organization so there is a big bias.
While they are a subsidy, I do not believe they are relevant at all to the argument. That's my point, I guess.
Corn, bean, and other row crop subsidies, sure. But BLM is just a distraction, I think.
Edit: The $38bn appears to also include egg and dairy subsidies, but Americans appear to spend substantially less per annum on those commodities compared to meat[3][4], such that the federal subsidies still appear to make up a rather large fraction of the (retail value of!) annual consumption.
