A rapid of determining erosion resistance of soil in field conditions is theoretically substantiated. The equation of motion of soil particles in an inhomogeneous electrostatic field is considered and numerically solved. It is shown that particle escape transport in the electrostatic field under the effect of the wind flow are analogous to force interactions. A differential equation of motion of soil particle in an inhomogeneous electrostatic field is considered and numerically solved. Factors determining the rate of particle escape outside the field are found. A possibility of determining the critical wind speed when the separation of soil particles starts from the minimum electrostatic field strength at which a similar process begins is proved theoretically and confirmed experimentally.
