| Brandon, Your observation on two crop rotation is absolutely correct. In fact, if you stick with a two crop rotation on each unit, you would eventually end up with ten years of history spread over twenty years, meaning extremely outdated yield data in your APH. Now, throw in a couple of drought years, and you might have a really subpar actual history, even though genetics and practice show yields trending higher.
I have some customers who use a three year rotation (corn/milo, soybeans/sunflowers, wheat), who must now live with two or three years of drought yields in their history for twenty or more years, theoretically. | |
