Possible long-term Sanguine impact on soil arthropods was studied in nine test plots and six control plots. Comparisons of test and control populations of mites and Collembola include statistical treatment of within-year and between-year numbers, predator proportions, Cryptostigmata Collembola ratios, and Cryptostigmata Mesostigmata ratios. A striking result is the synchronicity and uniform amplitude of population cycles seen in a three-year perspective in the control and test plots. These similarities in population numbers are supported by analysis of variance in all cases but one. The observations support a conclusion that following four years of operation, Sanguine electromagnetic fields have had no demonstrable effect on the arthropod populations under study.
