The dependence of the clay particle diameter (y) on the clay content (Clay), carbon concentration in clay (C Clay ), zeta potential (ζ), polydispersity (Poly), and pH of the aqueous suspensions of ograno-clay complexes;. coefficients of the multiple linear regression statistical model у = A 0 +A 1 x 1 + A 2 x 2 + A 3 x 3 + A 4 x 4 + A 5 x 5 , P < 0.05. The entire data set (all stud- ied horizons, n = 42) was used for calculations

Dynamic light scattering (DLS) and phase analysis light scattering (PALS) have been used to study the physical and chemical characteristics of organo-clay complexes of soddy-podzolic soils (Albic Retisols (Loamic, Cutanic, Differentic, Ochric)) of forest sites of the Central Forest Reserve. The study of the chrono-sequence of abandoned agricultural...

... into consideration the importance of the organo-clay complexes in soil aggregation, the multiple linear regression statistical models to predict the average diameter of clay particles were calculated. The following parameters were used in the model: clay content, carbon concentration in clay (C Clay ), zeta potential (ζ), polydipersity (Poly), and pH of the aqueous suspension of the organo-clay complexes (Table 3). At the initial stage, for models describing the average diameter of clay particles <1 μm in size, all parameters for the entire data set were used. ...Citations
Microscopic mechanisms have played a central role during development of different natural sciences and should be the key to construct new foundations for soil science. Abundant surface charge is probably the most important characteristic for soil systems and critical to soil interfacial processes. In this perspective, we discussed (1) more than ten techniques to determine surface charge, (2) different classical theories used to interpret soil interfacial processes and (3) recent progresses on microscopic mechanisms of soil interfacial processes focusing on new theories, ion exchange, clay aggregation, aggregates stability and water infiltration. It manifested that non-classical polarization can account for these microscopic mechanisms, and an updated understanding in this regard was offered. Suggestions were then posed with respect to development of soil science.
