Study on impact of precipitation pH and conductivity on soil resistivity

In this paper, the impact of precipitation pH and conductivity on soil resistivity were studied by analyzing observation data of precipitation pH value and conductivity (K value) and simultaneous observation data of resistivity at different depths of soil for one year. The results indicated that “daily average resistivity for different depths of soil at a fixed location in the same area has a significant positive correlation with daily precipitation K value, which is a result of combined effects of significant negative correlation between daily precipitation and daily average resistivity at different depths of soil and the negative correlation between daily precipitation and daily precipitation K value; therefore, the capability of the concentration of charged ions in precipitation is far weaker than that of daily precipitation to improve soil conductivity, and the impact of daily precipitation pH value and conductivity on soil resistivity is negligible compared with that of daily precipitation”. And it was discovered that the principle of only relying on using resistance reducing agent to offer the limited charged ion for soil to improve soil resistivity to reduce grounding resistance in resistance reducing agent product research and development is unscientific and incomplete. We proposes that it must follow the principles of low resistivity, moisture absorption and water retention for resistance reducing agent product research and development, which provides a scientific basis for making a correct technological route.
