STATIONARY COMPLEX FOR EXPRESS-ESTIMATION OF DYNAMICS OF ELECTRIC ACTIVITY OF SOILS Russian patent published in 2006 - IPC G01N33/24 

FIELD: ecological monitoring technologies, diagnostics of functional state of soil types, possible use in agriculture, soil science when performing researching, land-surveying and other types of operations.

SUBSTANCE: stationary complex for express-estimation of dynamics of electric activity of soils contains measuring and standard electrodes, connected via signals transformer assembly and communication line to block for their processing and indication and additional moisture saturation and temperature indicators. Signals processing assembly is positioned in metallic body and contains instrumental amplifier, connected by its inputs to measuring, standard electrodes and to moisture and soil temperature indicators, and by output through communication line - to analog-digital converter, connected through serially enabled microprocessor computing device and galvanic decoupling to indicator. Metallic body is made in form of cylinder, wherein a vessel is positioned with researched soil sample positioned therein, and also measuring and standard electrodes, indicators of temperature, moisture, while vessel is mounted within electrostatic magnetic screen. On basis of levels of amplitudes and values of frequency spectrum of electric signals of soil it is possible to estimate character of dynamics of its electric activity and determine fine structure of dynamic stability zones.

EFFECT: increased speed of operation, increased trustworthiness of estimation of dynamics of electric activity of soils.
