[Morsul the Dark]

I didn't want to start a new thread for this but I can't find the thread about food production in Mordor...

anyway heres the general Idea someonme argued there have to be fields east of mordor so saruon can feed his people. well if this is true I can imagine orcs tending them so is it possible the entwives were enslaved by sauron to attend the fields under threat of fire the brownlands could possibly be the site of battle in which they were enslaved....?
