Mysterious spots in intensively cultivated agricultural fields?

[Christophe]

Photo taken by a paramotorist in France: some fields show spots they look like "buttons" ... like a measles !!

Any idea what this can be ???

(apart from huge regular engine oil leaks ... or more seriously, surges or pockets of surface water? but which do not appear in the other plots therefore ????)

Didier?

Water drops on the visor through which the camera sees the image.
We can see that these are shadows.

uh no I don't think so, at the limit between the bare field and the green field at the top left, we can clearly see that the spots are only on the field. naked. On the other hand you see long shadows of a kind of bell tower (or a silo?) Which cover the two fields, it is very different.

It seems real and really linked to the plowing of the bare field, could it be depressions which are more humid after a rain?

Of course you did it complete overview of the side effects of your vaccination ?

[Christophe]

Could it be depressions that are wetter after a rain?

Yes ... it could but why nothing in the plot at the top left of the photo in the distance?

Is itaches would not be precisely a consequence of tâspecific issues?
Let me explain: imagine that heaps of organic matter have accumulated, intentionally or not (in the latter case, by fall during a harvest, for example): therefore, the higher water retention and / or the coloring darker could easily be explained ...

Christophe, you ask:

Yes ... it could, but why nothing in the plot at the top left of the photo in the distance?

Because this plot does not belong to the same farmer or has not been the subject of deposits.

[Christophe]

Yes it is a possibility ... but which piles remain long enough dispersed like that randomly on a field ??

Straw or hay bales? YES !!

But the scale does not seem good to me! The tasks are too large and some are too close together ... boots are laid "regularly" ...

But the hypothesis is interesting!

I can't wait to read Didier's review!

[Ahmed]

It is not necessary that real piles remain in place for a long time, simply that organic matter is deposited, as is the case during the ejection of the straw or hay bale ... The passage of surface tillage tools then suffice to spread this mulch and explain this configuration.

[Christophe]

Yes it's a good hypothesis, the best for the moment, when I said regularly it was not the duration but of geometry ... it seems to me a little too random to be boots ... no?

[Ahmed]

Sorry, but I was not there at the time of the incident.
