“Living construction” describes the process of “cementing” soil particles through the life processes of soil animals. Clay and humus particles are connected to each other. On the one hand, crumbs are formed with the help of mucus and excrement, on the other hand, tube systems are created that create favourable conditions for the air and water balance. All in all, a high level of soil activity and the associated living structures increase the stability of the soil against erosion and capping.
