in contrast to the later images in this series, this one has a dull uniformity to it that I read as sick, but for all I know this is what "healthy" soil is supposed to look like when analyzed in this way. Or it could be that whatever the agrotoxin is, it's evident in the dark blob just outside the blank center (some substance that did not move in the analysis) or in the ring toward the outer edge (a substance that moved the furthest in the analysis). In contrast to the other (prettier) images that are patterned uniformly over the entire circular area, this one is the only one with inner/outer differentiation
