The productive potential of a soil can be estimated by indicators of properties, processes or physical, chemical and biological characteristics that can reflect their level of support in the cultivation and development of plants. The adaptations of Ehrenfried Pfeiffer (1899-1961) to the work developed in biodynamics by Kolisko and Kolisko (1939) gave rise to Pfeiffer’s circular chromatography (PCC), used to analyze the quality of soils. The digitalization of chromatograms gives greater reliability to the technique as it allows the correlation of soil properties by their level of organization and that this can be correlated with quality/health. High dynamized dilutions and homeopathy are regulated in organic production in Brazil and have shown excellent results in agriculture in various parts of the world. The objective of this work was to evaluate the changes that occur in soils treated with high dynamized dilutions by PCC statistics to verify the alterations in the chromatograms. The experiment was conducted in Fraiburgo, SC, Brazil. Soil samples were obtained in a permanent preservation area at a depth of up to 15 cm. The highly dynamized dilutions were obtained in the laboratory of Homeopathy and Plant Health of Lages/Epagri. The design of randomized complete blocks was used, each treatment originated 10 blocks, one container of each treatment, in each container three subsamples were performed, 30 chromatograms per treatment. The treatments were: i)distilled water; ii)30% ethyl alcohol; iii) Calcarea carbonica 30CH; and iv) Silicea terra 30CH. The design was in randomized blocks. The entropy parameter was shown to be the most effective variable in the digitalized analysis of PCC chromatography using the algorithms (14 in total) present in the ImageJ Texture Analyzer plug-in. Calcarea carbonica 30CH and Silicea terra 30CH had the highest MZ (median zone) values, while Silicea terra 30CH was significantly superior to treatments.
