Mysterious spots in intensively cultivated agricultural fields?

[Obamot]

Because there are contrasts with a very yellow field and the rest is too far away?

No.

Because the speckled / cleared sky only covers part of the sky? And therefore is not visible elsewhere.

And for the rest, I don't care ( ) it's just my 2 cents of € uros ... this is where I found the most convergent / concordant clues .... such differences in relief, would not give an appearance of homogeneity of similar surface, no phenomenon of drop shadows that I mention (yellow), no differences in color temperatures as characteristic ... (all) no intermediate zones with more enlarged spots and merging, (blue and green ) no density of pixels which vary with the distance of the observer on such short distances (black) it does not hold. All the above phenomena are correlative

It is a nebulous hypothesis coming out of a hazy mind ...

in your cloud story, what disturbs me is the spread of the spots that seem to stretch with the plowing, with like stripes, a fluffy sky would give I think more compact and more circular spots

the clouds which give beautiful shadows like the ones you evoke are those of low altitude clouds, like those in your photo, the more the shadow is frank the more the cloud is compact and there the shadows are very dark therefore compact clouds, in in any case more compact than those in your photo

It is a nebulous hypothesis coming out of a hazy mind ...

If we had differences in relief on the ground, this would induce variations in the upper line of crops, but the line is homogeneous, straight and almost perfect, but it is a “hazy” explanation whereas yours is clear but devoid of argument

It would be interesting to know where this photo was taken .... The place may very well have been the theater of bombings during one of the last two wars .... It leaves traces for a long time .... Especially in open fields

But the other bare fields, at the top of the image, do not have any ... Such precise bombardments on agricultural plots, which stop dead at the limit, I do not believe much ... Without speaking that, on the other hand, it is always seen in the form of slight bowls ...

[Obamot]

I know a good optician, however ...

The marks of rotation of the tractor, put in perspective of the size of the spots and their progressive outlines, still attest to the signature of a shadow made by these small clouds,

My comment was only a form of humor ... For all that your arguments are rather vaporous, while mine, although not absolutely conclusive (it lacks elements for that) emerge from my experience of convinced and practicing earthling .
It is possible that the photo was taken after harrowing or other superficial cultivation, in which case the more or less dark variations of the streaks would be due to differential evaporation where drier = lighter ...

[Obamot]

My comment was only one forms of humor ... [...] differential evaporation where drier

Mine too

Let's say my arguments are vaporous, the next stage, while yours are wet and evanescent
