I'm curious on the numbers on this. Every time the general topic comes up, avocados and bananas seem to come up and completely spurn the idea. Googling says 80+% of crops are rotated on a regular basis. Though, it is noted that "cover crops" are sub 10% of rotations. Which seem to be required for fruit farms.

At any rate, I'll be reading more on this some. I have real work I should be doing, after all. :D
