The paper presents method to determine soil aggregates water stability. Its main stages are vacuuming of aggregates to eliminate the uncontrolled influence of trapped air on their destruction, subsequent saturation of aggregates with water in vacuum to values of soil moisture potential close to zero, and the use of vibration, to accelerate the destruction of aggregates. The influence of the vibration amplitude on the water stability of soil aggregates of the zonal series was studied using the

It is shown that obtained curves have a general form for all the studied types of soil, a weak destruction of aggregates with vibration increase at the initial stage is replaced by a sharp acceleration of their destruction when the maximum value of the impact is reached. Despite the lower information content in comparison with traditional methods of sieving method, the proposed approach for assessing water stability has a noticeably higher performance and can be used as an express method for determining aggregate water stability and techniques for increasing it.
