Ken said he would (where possible) position the antenna so the center of
the path was passing over a tree.
I guess if the issue was destructive reflections off the corn then the
tree attenuates those reflections?

First time I ever heard about this was many years ago from Ken Hohof.
Corn and pine trees seem to have a unique effect on RF.

Subject: [AFMUG] 5Ghz thermal fade w/ Corn
I have a customer on a PMP450 SM at 5Ghz link only 2.8 miles out. This
SM normally sits at -62 or -65. Every evening for the last 2 months SM
will fade to -80 or worse and sometimes even disconnecting for a couple
hours then it comes right back. AP is 120 feet height customer CPE
height is about 15' height
There is alot of corn fields across this link i have in the past seen
problems with corn links. I don't know why but shooting across corn is
sometimes a problem.
Other thing i thought of is the AP is mounted on top of of a very large
steel grain bin that probably is heating up during the day maybe it is
giving off heat when the sun first goes down we have started to get
cool in the evenings here.
I am about ready to move customer to a different frequency band he is
pissed his Netflix is not working during prime time.
