Application of geo-electric methods in automated irrigation systems

Tsaplev A.V., Kuzichkin O.R.

The paper deals with the issue of using geo-electric methods for monitoring soil water saturation in an automated irrigation system. The ways and guidelines for applying geo-electric methods in local monitoring of soil electrical conductivity are studied. Parametric dependence of local conductivity on soil moisture is proved. Troublesome factors affecting electrical conductivity value are identified.  Measurement results appear to be mostly affected by temperature variations in the environment. A mathematical model for describing soil layer parameters and its water saturation as geo-electric functional dependencies is given. In the paper, the correction algorithm of time sequence for automated irrigation monitoring systems to eliminate temperature influence is developed. The algorithm can also be used in geo-environmental soil monitoring systems, based on geo-electrical methods of geodynamic monitoring.
Keywords: automated monitoring systems, geo-electric control, water saturation, electrical conductivity, temperature influence.
