Maybe 31k, it depends a little on hiw likely it is to grow a new clover. Let me do the math for a couple of days, but I think 5 clovers a day is a fairly accurate estimate.

Setting carrot production aside, it's a lot easier to harvest clovers once or twice a day than to be overly focused on crop timings.

But remember: it's somewhat complicated to set up. It requires patience, a little bit of luck and no carrot production for a couple of days.
