Correct me if I'm wrong, but aren't most pastures also planted, fertilized, and watered? You're also assuming infinite land here - I don't know shit about farming, but the first google hit I got suggests that cows need about 1.8 acres of pasture per year.
1 cow, consuming 1.8 acres of land, produces on the scale of 0.5 to 1.4 million calories, according to this estimate
However farming produces up to 18 million calories per acre, so if you were growing potatoes you'd have 32 million calories. On the same land that produced up to 1.4 million calories via grazing cow.
no, i'm not. i was comparing the work done to plant a field of potatoes against raising an equivalent amount of cattle. i'm making no sweeping policy proposals.
Great, in a vacuum, and assuming efficiency of land does not matter, you are correct in saying it takes less work to produce less calories.
not just in a vaccuum but literally any time you have the option to plant a field or put a cow in it, it will always be less work to put a cow in it.
so? the work of lettin a cow eat what grows is still less work than planting, tending, and harvesting.
no. they're grasslands, and hilly terrain or rocky soil is a common feature of land designated as pastures because of the difficulty of working the land.
if you ask a seed salesman whether you should buy his product for your pasture, he'll try to sell it to you. but no, for the most part pasture management is very low intensity: repair fences and deter predators. these have direct analogues in raising crops though in warding off pests that would eat the crops.
