Not sure what you’re putting on yours but mine is probably less than $100.00 per acre per year.The only thing cheap about a clover plot is the clover seed. Factor in everything else and it adds up to a nice chunk of change. $500 per acre per year give or take to maintain. Nice not having to totally start from scratch every fall and feeds them year round! Even when I have a feeder out they spend more time with their head down in the clover than under the feeder!
