i wasn't referring to rotation here, as Martin didn't appear to be 
tracking crops, only identifying distinct fields.

i do agree on the rotation, my family's land in Iowa is in strict 
rotation. but per the bit rot issue, we did adjust some boundaries 
within the
past 2 years. or else, a land holder buys an additional 100 acre field and
adjusts the rotation to match their operational requirements


you could record this easily enough, but like i say, bit rot will set in and
it's unclear what value we gain from this in normal mapping of the here
and now. for historical mapping, it's important in say, battlefield 
where troops attacking through head-high corn are distinctly different from
troops attacking through shin-high soybeans or waist-high sorghum
