"In the figure at left we can observe a dark, grayish outer ring enclosing everything else. Directly inside it, there is a thicker, irregular, brown, and, we might want to say, “unharmonious” ring, about an inch thick. Occupying most of the figure is a large violet disc, with a smaller disc at the very center of the image. There is little interaction between these different zones, apart from the protuberances erupting from the brown ring into the outer, grayish belt. None of the regions is “relating” to the others. The figure as a whole gives the impression of stagnation.
The second figure looks rather like the iris of an eye. One senses in the whole a movement radiating centrifugally all the way out to the edge of the filter paper. Instead of a dark ring enclosing everything else, we find an open, light- beige outer circle. Spike-like formations interpenetrate this outer layer, and at the tip of each “spear” there are brown spots. These “spurs” correspond to the brown ring of the first figure. The inner main disc has brownish hues, instead of violet, and is filled with feather-like radiations. Unlike in Figure 1, each region harmoniously relates to and interpenetrates the other. The picture gives a sense of movement, development, and harmony.
Figure 1 represents an anaerobic and stagnated compost of very poor quality, while Figure 2 is a sample from an excellent humidified compost. " -
