"Crop is a produce"
What does that mean?
The word "crop" in British English means " a cultivated plant that is
grown on a large scale commercially, especially a cereal, fruit, or
vegetable. (Oxford); or "a plant such as a grain, fruit, or vegetable
grown in large amounts" (Cambridge).
Plants are not produce, "produce" is the thing that a plant produces,
in OSM: "Describes a feature's agricultural output..." - so the word
"crop" is not appropriate, because "crop" is not the agricultural
output of an area of farmland, but a category.
'Crop' Look at the values used for crop crop=coconut, crop=wheat,
crop=hay etc. All of the reasonable ones are also 'produce'.
(Unreasonable ones such as 'market gardening are not crops so fail as
produce too.) Look at the OSM description: Crop: "The crop produced by
cultivated land." That would not be the plant but the output? And it
does not match the BE definition? 'Produce' Englishdictionary as nounis
defined by the Oxford English Dictionary as "Agricultural and other
natural products collectively." In OSM description: Describes a
feature's agricultural output produced though a natural process of
growing or breeding. The BE and OSM meanings are a much closer match for
'produce' where as they differ for 'crop'.
But I see that there is some desire for a tag for generic cropland, or
farmland used to grow unspecified crops. For this I would suggest the
key "farmland=cropland" or "crop=field_cropland", rather than crop=yes
(less specific) or produce=crop (unclear).
https://taginfo.openstreetmap.org/keys/farmland
https://taginfo.openstreetmap.org/tags/crop=field_cropland
Warin, if you do decide to use any of these tags, please document them
at a Tag: page or in your userspace or a proposal, if you have the
time.
There are many values for the key crop that lack documentation.
crop=field_cropland being one, I think that describes the landuse not the
output.
Another one that looks to me to be very bad is 'market_gardening'.
As these are 'common' yet lack documentation there is a need for them to be
documented by those that support them. Joseph?

Cannot farm land can be used for crops for some time, and then milk
cattle for some other period of time?
IIRC that is what one of my relatives did.
? Anyone care to comment?

But isn't that the definition of farmland in OSM? I would map meadows,
farmyards, and orchards with their respective tags, not with
landuse=farmland.

Produce=crop would be worse, because “crop” is not a type of
produce, and produce= is only very rarely used for crop land (
crop= is the established key for types of crops like rice,
sugarcane, wheat, etc)
The rate of present usage does not limit the use of a tag.
colour=#93006B <https://taginfo.openstreetmap.org/tags/colour=%2393006B>
is only used once in the data base ..
height=16 metres is only used once in the data base...
Crop is a produce.
produce=crop has 2 uses .. presently.
I have been mapping a small area where my family farmed for several
generations ... tomorrow there will be a lot more produce=crop.
If the judgement is simply on frequency of use the result may well be
wrong.
As I mentioned on the Talk:Key:crop page, I suspect that this tag
crop=yes is sometimes used to say “this area of farmland is used
as crop land”, that is, to grow row crops like
grains/sugarcane/other annuals. So at least we know it probably
isn’t a meadow or a farmyard or an orchard?
Vineyards have their own tag, should the tag crop=grapes be removed?

As produce could be fish, cattle, sheep, wool, or crops.
produce=crop would say that only crops are produced here.
