“…In the previous papers (Panova et al, 2017; 2019, 2020; Panova, Drobyazko, et al, 2019) we described the use of IPECs for stabilization of several types of soils/grounds with different contents of organic matter. It was shown that positively charged IPEC formed the strongest top layers on the soil/ground surface, which resisted wind and water erosion.…”

Chernozems or mollisols/black soils are 'reference soils' with a high content of organic matter, which ensures a high level of crop yield. In the article, we describe the structural characteristics of a typical medium‐thick Chernozem taken from Kursk region and their improvement via treatment by a 1 wt% aqueous solution/suspension of interpolyelectrolyte complex (IPEC), a product of electrostatic interaction between anionic potassium humates and cationic poly(diallyldimethylammonium chloride). The native Chernozem and polymer‐treated chernozem were characterized by laser diffraction, dry and wet sieving methods, transmission electron microscopy, soil washoff in a hydraulic erosion tray, gravimetry, visual control, and vegetation miniaturization in Petri dishes with the following main conclusions: (a) Deposition of a positively charged IPEC over the Chernozem sample led to an increase in a total amount of agronomically valuable 0.25–1 mm aggregates up to 28% in comparison with a 3% content of aggregates in the native Chernozem. (b) An average diameter of the air‐dry aggregates, treated by a cationic IPEC, was of 5.5 mm (cf. with 2.5 mm for the untreated). (c) An average diameter of the IPEC‐treated water‐resistant aggregates was of 2.1 mm (cf. with 0.5 for the untreated). (d) The Chernozem pretreated by the cationic IPEC showed a minimum removal of soil during several cycles of rewatering/drying. (e) All IPEC formulations, stimulated the growth of plants. The results are of interest for preparing low‐toxic polymer formulations capable of effective stabilizing fertile Chernozem soils.

“…Panova and coworkers investigated the possibility of using nonstoichiometric IPECs of synthetic and natural polymers such as poly(acrylic acid) and poly(diallyldimethylammonium chloride) (PDADMAC), 13 potassium salt of humic acid and PDADMAC 14 to stabilize soil and sand. All of the studied stabilizers show increasing mechanical strength of soil and sand after treatment.…”

“…1 The use of IPEC showed high efficiency for cotton plant cultivation and wild vegetation; this advantageous effect of the IPEC on sprouting can be explained by the greenhouse effect facilitated by the polymer crust, which slows the evaporation of moisture and heat loss from the soil surface. 10 Panova and coworkers investigated the possibility of using nonstoichiometric IPECs of synthetic and natural polymers such as poly(acrylic acid) and poly(diallyldimethylammonium chloride) (PDADMAC), 13 potassium salt of humic acid and PDADMAC 14 For this purpose, IPEC of hydrolyzed polyacrylonitrile-PDADMAC and carboxymethylcellulose (CMC)-PDADMAC were used. The method is very interesting because initial polymer solutions can be prepared in common vessel in the presence of low molecular weight salt.…”

Soil degradation is an important problem on a global scale. Suitable materials for its solution are interpolyelectrolyte complexes (IPEC) of biodegradable polymers. IPEC based on the oppositely charged pairs of biodegradable polymers-chitosan and sodium alginate (Ch-SA), chitosan and sodium carboxymethylcellulose (Ch-SC), and chitosan-gellan gum (Ch-GG) were prepared and studied using different physicochemical techniques (FTIR-spectroscopy, dynamic light scattering, conductometric and turbidimetric titration, and rheoviscometric measurements). Thin films of IPECs were prepared by pouring polymer solutions on a flat surface and subsequent evaporation of water. These films were tested using mechanical analysis. Young modulus of IPEC films increases in the following order: Ch-SC < Ch-GG < Ch-SA. Urban soil samples were sequentially treated with Ch solution and negatively charged polymer solution (SC, SA, GG). This technique of soil treatment leads to formation of IPEC within the soil surface layer. The soil structures and also soil treated with pure water and individual polymer solutions were also tested using mechanical analysis. It was found that the most durable structures are formed by IPEC based on Ch and SC. All the applied systems can be arranged in the following sequence in ascending order of the Young's modulus: GG < Ch < SA < Water < SC < Ch-GG < Ch-SA < Сh-SC. The IPEC based on biodegradable and biocompatible polymers of polysaccharide nature can be successfully used for soil structuring. These polymers significantly increase the mechanical strength of the soil without harmful effects to the environment. Among the studied systems, the Ch-SC system has the greatest structuring ability. These soil structuring agents can be applied for improving of the quality of urban and agricultural soils.
