Healthy soil structure is the one of the main prerequisites for sustainable and effective agricultural land use. Properties and arrangement of soil structural units called "aggregates" (Yudina & Kuzyakov, 2019) changes over the time and as consequence cause a shift in the structural state of the soil system. Due to these abilities to evolution and dynamics soil structure is a sensitive and indicative tool for the soil management and quantitative assessment of soil functions (Rabot et al., 2018). Timely and rapid assessment of soil structural change becomes a relevant scientific and practical task in the face of global climate change and intensification of anthropogenic impact on soils. For this purpose, it is necessary to have good indicators of soil structure quality.
