Abstract

One of the methods to increase the water stability and erosion resistance of soils is the use of structure-forming polymers. It is believed that the mechanism of their action is based on strengthening the bonds between particles of clay minerals. This approach ignores the existence of organomineral gels on the surface of mineral particles, which can affect the effectiveness of polymers. The purpose of this work is to investigate the interaction of a number of structure-formers used to increase water stability and erosion resistance with soil components. In model experiments on the interaction of polymers with soil components, suspensions of humate and bentonite are used. The results are verified on leached chernozem. The effectiveness of polymers is evaluated by the blade method used to determine the water stability of soils, and the interaction of particles in suspensions in model experiments is evaluated by laser diffractometry. It is established that, in solutions of humates with polymers, the size of particles formed in solutions increases with increasing hydrophobicity of the polymers. No such unambiguous relationship is found in bentonite suspensions with polymers. Verification of the results of model experiments on chernozem has shown that the water stability of the aggregates increases with an increase in the hydrophobicity of the polymer used for treatment. To further verify the role of organic matter in ensuring soil water stability, the possibility of using oppositely charged humic substances and iron sol to increase soil water stability is evaluated. The experiments have shown that the use of iron sol increases the water stability of chernozem. Moreover, at an increase in the pH of the iron sol solution from 1.7 to 6.1, the effect value increases from 11 to 59%. The results of this study suggest that shifting focus from strengthening the adhesion between mineral particles to strengthening organic and organomineral interactions should be considered as a reserve for increasing the effectiveness of compositions to maintain the soil structure.

关于提高土壤水稳定性的观点分析
摘要 提高土壤水稳定性和抗侵蚀性的方法之一是使用结构形成聚合物。一般认为,聚合物的作用机理是加强粘土矿物颗粒之间的结合。这种方法忽略了矿物颗粒表面有机矿物质凝胶的存在,而这种凝胶会影响聚合物的效果。这项工作的目的是研究一些用于提高水稳定性和抗侵蚀性的结构形成剂与土壤成分之间的相互作用。在聚合物与土壤成分相互作用的模型实验中,使用了腐植酸盐和膨润土悬浮液。实验结果在沥滤过的 Chernozem 上得到验证。聚合物的有效性通过用于确定土壤水稳定性的叶片法进行评估,而模型实验中悬浮液中颗粒的相互作用则通过激光衍射仪进行评估。结果表明,在腐殖酸盐与聚合物的溶液中,溶液中形成的颗粒大小随着聚合物疏水性的增加而增大。而在含有聚合物的膨润土悬浮液中,则没有发现这种明确的关系。对 Chernozem 模型实验结果的验证表明,随着用于处理的聚合物疏水性的增加,聚集体的水稳定性也会增加。为了进一步验证有机物在确保土壤水稳定性方面的作用,对使用带相反电荷的腐殖质和铁溶胶来提高土壤水稳定性的可能性进行了评估。实验结果表明,铁溶胶的使用能提高 Chernozem 的水稳定性。此外,铁溶胶溶液的 pH 值从 1.7 提高到 6.1 时,效果值从 11%提高到 59%。这项研究的结果表明,应考虑将重点从加强矿物颗粒之间的粘附力转移到加强有机物和有机矿物之间的相互作用上,以此作为提高成分有效性以保持土壤结构的储备。
