based on the evidence presented - my first thoughts are chemicals NOT a heat source
my likley cuprits would be either lime or anhydrous sodium hydroxide - both easily handled and applied - and cheap to buy in bulk
the basis of this peliminary is the lack of any combistion / charring - the dead grass is uniformly withered - and the circle affected is withered
down to the ground - with ZERO damage to the grass imediatly outside the circle
the " heat source " required to do all od this in a single pass takes on near magical properties - to apply a uniform heating over such a vast area
- without causing any combustion from hotspots or damaging the surroundings
chemicals OTOH can be applied with precision
PS - the chemicals explaination even answers the origin ofthe the concentric patern of ever decreacing radius circles -
because the way i would do it is to use a ground stake in the centre of the circle - and tether a small 2 wheeled hand pushed spreader to it - and
simply shorten the rope by the width of the spreader each rrevolution
simple plausible , and possible
i will not address motive for the hoax method - but before anyone leaps on this - what is the motive for ` other ` explainations ???
EDITTED : to add
here is a pic of the type of hand powered spreader i would use to create such a circle - with chemicals
that is how simple and easy it would be - all you need its 1 strong and fit chap to push the spreader - and dependant on how fast you wish to work - a
couple of assistants to haul sacks of chemical to him to refill the hopper as required
