The equation of motion of soil particles in an inhomogeneous 
electrostatic field has been considered and solved numerically. The 
factors determining the rate at which particles are carried away from 
the field have been established. It is shown that the processes of 
the carrying away of particles in the electrostatic field and under 
the action of the air flow have analogs. The theory is intended to 
substantiate the rapid method of determination of the predisposition 
of soils to wind erosion under natural conditions.
