Method of determining the stability of soil aggregates and the equipment for this

摘要

A method for determining the stability of soil aggregates by measuring the reduction in light transmission and an apparatus for carrying out this method, characterized in that it consists of a surface lighting source (1) on which a measuring container (2) can be filled with water. The bottom of the measuring container (2) is transparent and is thinned in places of optimal storage of soil aggregates by a shallow depression of the bottom material, the walls of the device are opaque to light and the bottom of the measuring container is arranged for backlighting by a surface light source (1) covered by a lid (3) which rests on the container so that light enters the measuring container from the outside. The lid (3) is fitted on the underside with a photodiode (4) for measuring the reduction in light transmission over time, caused by the breakdown of soil aggregates in the measuring vessel (2) .σ
