Whether soil pH and EC is really indirectly proportional or not. Please share your thoughts with some scientific reference.
According to a study soil pH and EC are negatively related to each other. The complete details are given in the following article.

PH and EC are quite different parameters. They don’t have any relation.
Dear Dr Debabrata Nath . They relate to each other directly. lower soil pH indicates larger number of hydrogen ions in the soil. Hydrogen ions can appear in varying amount in the soil environment which can affect the level of electrical conductivity..

Soil pH affects all the physical, biological and chemical soil properties and the growth of specific organisms, soil microbial biomass, and microbial activity. The pH of a soil is a measure of the active acidity, that portion of hydrogen ions that is active in soil solution where the negative logarithm of hydrogen concentration is used as an indicator and is measured in pH units. The EC is a measurement of dissolved materials in aqueous solution which relates to the ability of the material to conduct electrical current through it. However, Soil PH has a negative relationship with soil electrical conductivity.
