A crop circle or crop formation is a pattern created by flattening a crop.
Although obscure natural causes or alien origins of crop circles are suggested by conspiracy theorists and other UFO enthusiasts, there is no scientific evidence for such explanations. Scientists maintain that all crop circles are consistent with some kind of human interference or creation.
One such example of crop circles created by humans occurred in Japan. Scroll down to see what happened…
Back in 1973 scientists began a project in ‘experimental forestry,’ with the aim of learning about the spacing of trees and its effect on growth. They planted circles of cedars near Nichinan City in Miyazaki Prefecture, with smaller inner circles expanding incrementally into larger radiuses to create 10 perfect rings.
As you can see in the photo below, the experiment seems to show clear results. The concave shape suggests that the outer circles of least density promote a higher growth, with the tree size getting steadily smaller as the density increases.
Makes sense right? More space equals less competition for resources such as water and sunlight, so it’s easier for these outer trees to grow bigger and stronger while those on the inside fight it out amongst themselves.
According to a document from Japan’s Ministry of Agriculture, Forestry and Fisheries, the eventual height difference between the smallest trees at the center and the tallest trees on the outer ring was over 5 meters.
The trees are due to be harvested soon, with the experiment drawing to a close. But such is the interest in this unexpectedly beautiful result there remains the possibility that these giant ‘crop circles’ could be preserved, and perhaps even become a tourist attraction in the future!
