“…Additionally, Klivenko et al used biodegradable polymer IPECs and tested soil structures with individual polymer solutions and mixtures, obtaining the following sequence in ascending order of Young's modulus: gellan gum (GG) < chitosan (Ch) < sodium alginate (SA) < sodium carboxymethylcellulose (SC) < Ch-GG < Ch-SA < Ch-SC. For Ch-SC, the maximum resistance value was 430 kPa [106,107]. Furthermore, Lerma et al developed a hybrid compound utilizing montmorillonite and poly(acrylic acid) mimicking the structural and functional properties of humified soil for soil retransformation strategies.…”

In recent decades, polyelectrolytes (PELs) have attracted significant interest owing to a surge in research dedicated to the development of new technologies and applications at the biological level. Polyelectrolytes are macromolecules of which a substantial portion of the constituent units contains ionizable or ionic groups. These macromolecules demonstrate varied behaviors across different pH ranges, ionic strengths, and concentrations, making them fascinating subjects within the scientific community. The aim of this review is to present a comprehensive survey of the progress in the application studies of polyelectrolytes and their derivatives in various fields that are vital for the advancement, conservation, and technological progress of the planet, including agriculture, environmental science, and medicine. Through this bibliographic review, we seek to highlight the significance of these materials and their extensive range of applications in modern times.

“…Recently, polymers of natural origin, mainly polysaccharides, i.e., salts of alginic acid and carboxymethyl cellulose, chitosan, etc., have been put into practice [23][24][25][26][27]. Physical factors and soil microorganisms stimulate degradation of these biopolymers down to low molecular weight compounds, thus significantly reducing the environmental load on the soil.…”

“…Physical factors and soil microorganisms stimulate degradation of these biopolymers down to low molecular weight compounds, thus significantly reducing the environmental load on the soil. At the same time, the polysaccharide IPECs, described in the literature, are mostly stoichiometric formulations with an equimolar charge-to-charge ratio of cationic and anionic biopolymers [23,26,27]. Such IPECs are insoluble in water that makes them difficult to work with [13,26].…”

Biodegradable Interpolycomplexes for Anti-Erosion Stabilization of Soil and Sand

et al. 2022

A linear anionic polysaccharide, sodium alginate, electrostatically interacts with a cationic polysaccharide, quaternized hydroxyethyl cellulose ethoxylate, in aqueous solution, thus giving an interpolyelectrolyte complex. Aqueous solutions of the initial polysaccharides and polycomplexes with an excess of the cationic or anionic polymers were used for the stabilization of soil and sand against water erosion. Physicochemical, mechanical and biological properties of the polymers and coatings were characterized by gravimetric analysis, viscosimetry, mechanical strength assessment, cell viability, and cell-mediated degradation with the following main conclusions. (a) Non-stoichiometric polycomplexes with an excess of cationic or anionic units (“cationic” and “anionic” polycomplexes, respectively) form transparent solutions or stable-in-time dispersions. (b) The complexation results in a decrease in the viscosity of polymer solutions. (c) A complete dissociation of polycomplexes to the initial components is achieved in a 0.2 M NaCl solution. (d) Soil/sand treatment with 1 wt% aqueous solutions of polymers or polycomplexes and further drying lead to the formation of strong composite coatings from polymer(s) and soil/sand particles. (e) Cationic polycomplexes form stronger coatings in comparison with anionic polycomplexes. (f) The polymer–soil coatings are stable towards re-watering, while the polymer–sand coatings show a much lower resistance to water. (g) The individual polysaccharides demonstrate a negligible toxicity to Gram-negative and Gram-positive bacteria and yeast. (h) The addition of Bacillus subtilis culture initiates the degradation of the polysaccharides and polycomplexes. (i) Films from polysaccharides and polycomplexes decompose down to small fragments after being in soil for 6 weeks. The results of the work are of importance for constructing water-resistant, low toxicity and biodegradable protective coatings for soil and sand.

The purpose of the study is to assess the dynamics of the humus state of arable soils in connection with the distribution features of soil types and subtypes in the municipal regions of the Volga region of the Republic of Tatarstan (RT). The territory of the Volga region occupies 1014.3 thousand hectares, which is about 15% of the area of the Republic of Tatarstan. The Volga region includes 8 municipal districts: Apastovsky, Buinsky, Verkhneuslonsky, Drozhzhanovsky, Zelenodolsky, Kaybitsky, Kamsko-Ustinsky and Tetyushsky. The results of soil and agrochemical surveys conducted by the Federal State Budgetary Institution CAS “Tatarsky” over the past 35 years are summarized. For the first time, arable soils of the studied region were examined for humus content in 1986-1990. (IV cycle of agrochemical examination). The determination of humus was carried out according to the method of I.V. Tyurin as modified by TsINAO (GOST 26213-91). It has been established that the soil cover of two municipal districts (Buinsky and Drozhzhanovsky) is dominated by highly fertile chernozems, and the remaining six districts are dominated by gray forest soils. A comparison of the distribution of the main soil types in the Volga region and in the Republic of Tatarstan as a whole shows that the region under study appears to be a miniature copy of Tatarstan: in both cases, gray forest soils are dominant, and chernozems are subdominant. It is noted that over 35 years, the area of arable land in the region has decreased by 57 thousand hectares, presumably due to the withdrawal of less fertile land from agricultural use. It is indicated that this circumstance to a certain extent stabilized the humus state of the soils remaining in the arable land. The weighted average content of humus in the arable layer according to the cycles of agrochemical survey of soils in the studied region varied from 4.42 to 4.82%, however, these fluctuations turned out to be statistically insignificant (r = -0.06). There was a positive correlation and the highest degree of dependence of the weighted average humus content on the total share of chernozem and dark gray forest soils (R²=0.96).
