“…An increase in the content of silt + clay in the soil increases the proportion of macroaggregates with a simultaneous decrease in the proportion of microaggregates (<0.25 mm). Clay and silt are important mechanisms for stabilizing the carbon pool in soil (Das et al, 2022; Singh & Benbi, 2021; Wang et al, 2021). Chemical protection of SOC by clay minerals occurs mainly through adsorption reactions: cation bridge formation, anion exchange, hydrogen bonding, van der Waals interaction, co‐precipitation of organometallic complexes, ligand exchange and hydrophobic bond interactions (Rani, 2021; Sarkar et al, 2018).…”

The presence of aggregates of various sizes in the soil is an important condition for soil carbon sequestration. In this system, microbial biomass is a key link. This work was devoted to the study of the influence of land use systems on the distribution of SOС, MB-SIR, microbial activity and eco-physiological indices (qCO 2 , QR, MB-SIR/SOС and qCO 2 /SOС) in relation to the size of soil aggregates. The distribution of SOС, MB-SIR and mineralization activity among the aggregates was heterogeneous. In the soil of crop rotation, high mineralization activity and MB-SIR were found in the aggregates 0.5-0.1 mm, in the monoculture soil in aggregates <0.1 mm and in the control soil in the aggregates 1-0.25 mm. There was a general trend towards a decrease in microbial activity, MB-SIR and SOС availability with an increase in aggregate size. In agricultural soils, microbial activity was determined by large aggregates (>5 mm), while in the control soil, by the aggregates 5-1 mm. Depending on the type of site and the size of aggregates, the differences in microbial metabolism were revealed. The qCO 2 and QR values decreased, and the MB-SIR/SOС and qCO 2 /SOС increased in the series: control soil > crop rotation > monoculture. In the control soil, the values of the ecophysiological indices decreased with decreasing aggregate size. And vice versa, in agricultural soils, these parameters were the highest in the microaggregates (<0.25 mm). The monoculture soil, in contrast to the control soil and crop rotation soil, turned out to be more energy efficient.

“…Soil improvement can lead to a valuable increase in crop production and food quality particularly in the areas affected by soil degradation and environmental stresses. Traditional soil conditioning practices in agricultural lands are not based majorly on nanotechnology even [ [125] , [126] , [127] ]. However, there are several nanomaterials that can be used for soil conditioning [ 128 , 129 ].…”
