METHOD TO MONITOR SOIL STRUCTURE Russian patent published in 2012 - IPC G01N27/22 

FIELD: agriculture.

SUBSTANCE: method to monitor soil structure, in which moisture is periodically measured in natural soil with a thermostat-weight method. According to the invention, capacitance of a soil sensor is measured with insulated electrodes at the frequency from 50 kHz to 1 MHz, and the proportionality ratio (k₁) is calculated between relative changes of capacitance and moisture of natural soil, the value of the appropriate coefficient (k₂) is determined between relative changes of capacitance and moisture of the same soil with the damaged structure, the value k₁ is divided into k₂, and the parameter of natural soil structure is produced.

EFFECT: method makes it possible to both monitor soil structure and assess its initial structure by comparison with the same soil of damaged structure.
