Not hay!

 

[Dave45]

any ideas

 

[wolfmanjoe3]

I grew up on a farm and those are definitely not hay bales. Too big - based on comparison with other things in the photo (road, buildings) they appear to be 20-30 feet across. Plus, farmers don't store them on their side so you wouldn't see the round side from the air. But not big enough (or enough coverage) to be irrigation circles.

​

Hard to tell from a vertical view, but the circles do not appear to have any height. No shadows or any appearance of depth - so that rules out crop circles... I took a class in aerial photo interpretation, so I feel like I should be able to figure this out, but I"m stumped right now. What part of the country is this? Most of the circles are almost perfectly round, so it is probably not a plant or result of a natural occurrence. It looks like a farm field - so probably the result of some human action.

That's my 2 cents for tonight. Hopefully others can shed some light...

There seems to be a black dot dead center in each of them. Tree saplings with mulch around them? tetherball tournament grounds ?

Is there any indication as to location? Where is the pic from?

These rings are most likely irrigation circles and probably are for distribution of manure slurry.

This farm probably has a large hog operation or a large dairy that results in excessive manure stockpiles.

There are agricultural sprinklers that are capable of throwing a 1200 foot radius.

I would think that kind of operation would be more evenly distributed...

In my opinion, the heads are evenly distributed. The reason that the circles are small is because the spray heads are not fully operatikonal..

Also having grown up on a farm, I am familiar with this type of operation.

And, believe me you don't want to be anywhere near when the system is operational unless you want to smell like pig crap.

With most systems, the heads are placed either in a triangular or square pattern and typically, a head that is not operating properly will leave a brown spot that is visible from the air. The spacing of the head is precisely equal to the distance of the spray...may be adjusted with diurnal wind patterns.

The reason for the dark centers is that most heads (regardless of manufacturer), the spray is not efficient nearest the head, therefore the opposing head from a square or triangular pattern will overlap to provide uniform precipitation.

What you are seeing are inoperable heads that are plugged, damaged or possibly even not getting adequate pumping pressure.

The areas without the dry circles indicates a fully operational systems.

Sounds good to me!

good evening,
I know the farm its not a hog farm, woudnt the circles be a darker green than the surrounding area if these were sprinklers, also the pattern is very uneven if you were to lay out sprinklers youd try to get an even coverage. Ive looked over a very large area and no other circles just this one field. If this were some kind of reflection or interference haveing to do with the satilite Id think it would cover a different area this stays within the confines of the field. Very strange any more ideas

Actually the opposite. The brown areas (circles) are areas that are not getting coverage due to nonfunctional heads. Most likely the GPM output is so large that they are using valve-in-head assemblies...so only one or two heads is operating at a time...also due to pump capacity...most likely they are pumping 100 to 150 GPM, or more.

Gotta remember that this system is not like a residential yard or football field sprinkler system. We are talking about heads that have a bore the size of your finger and are using what is called a scrubber valve for reclaimed effluent water...slurry water that has solid particles composed of solid clumps, grasses and other undigested feed. The system may also be mounted on a wheeled gear rotor (Volume Gun Tripods and Carts)that travels as the heads operate.

If you know the farm, possibly you could make a field inspection to ascertain what is actually happening.

Right now we are making assumptions based on an aerial view from about 5000 feet.

Hmm...I'm new to the forum, but I do have a thought or two on the origin of these. Main question I have is, where is this, geographically speaking? The marks remind me of impact marks, such as from mortars or craters.

If the photo's from Europe, I would suspect something like old bombing run crater marks in the ground. Residue might cause the discolouration. If it's in the U.S., could it be Civil War-era?

Just a thought from a newbie...

look around austin texas those are common dry spots of over growing

You could be right about round bales,....when horses or cattle eat (and ours sometimes nap in them) at the round bales they generally trash the ground around them,...thats why you don't really put them in the same place , you move them around the fields to keep them from edstroying a patch of ground.

Exactly what I see here, not all the circles are round, they seem to have different states of degradation,...also note that they are semi deployed in a line,...like a tractor went out in a filed and dropped one in line, but further down each day.

Also evidence of animal trails and a well used padock area, only thing I don't immeadiately see is much water, but there could be some small troughs around that I'm not looking hard enough for

Looks to me like something got on the negative or the photo paper?
