“…Introduced in May, 2018, saponite water suspension over the summer contributed to a significant decrease in the concentration of H + ions, which is proved by an increase in pH and a decrease in hydrolytic acidity. Similar results were obtained by other authors (Kozlov et al 2019, Nakvasina et al 2015. The effect can be exploited by the sorption capacity of saponite particles.…”

“…But, in addition to lime, other agrochemicals containing calcium carbonate can be applied. For example, agriculture organizations can use various clay minerals to increase soil fertility (Korolev 2007, Kozlov et al 2017, 2019, Tsykalov and Bobreshov 2013, such as saponite (Bosak and Sachivko 2016, Bosak et al 2016a, b, Streltsova et al 2016, 2017.…”

Increased soil acidity remains one of the important problems in world agriculture, especially relevant for the Northern territories, Traditionally, it is solved using lime ameliorants. Searching for new ameliorants that are just as effective, but at the same time are more are more accessible to certain areas is a promising direction for the development of agricultural science. Saponite water suspension can become effective ameliorant to improve acidic properties of soil on the territory of the Arkhangelsk region (Russia). This is possible due to the unique properties of saponite, its availability and the presence of large reserves in the region. This article presents the results of an experiment conducted in the Kholmogorsky district of the Arkhangelsk region (Russia) on sod-weak podzolic loam tame soil to identify the effect of saponite water suspension on acidic properties of soil under a naked fallow condition. The experiment proves the dependence of the seasonality of application, the different proportions of saponite water suspension and changes in pH and hydrolytic acidity, as well as the estimation of the most effective proportions of saponite water suspension to improve acidic properties of soil and revealed differences in the influence of seasonal application on the manifestations of the deoxidizing ability of saponite water suspension.

The purpose of this work is to obtain and evaluate the fertilizing ability of the clay-nitrogen mixture. The relevance of the research lies in studying issues related to the minimization of nitrogen losses when producing the clay-nitrogen fertilizer, the transformation of nitrogen from fertilizer into the soil, and the effectiveness of fertilization when growing barley. The data on the content of nitrate nitrogen (250,986 mg/kg) and the total one (5.0%) indicate the effective binding of nitric acid by clay. The fertilizer can be considered potassium-containing, since the content of mobile and total potassium is respectively 1,250 mg/kg and 0.20%. Mobile phosphorus in the fertilizer is low compared to potassium (76 mg/kg), although the total pool is twice as large (0.45%). The content of the gross form of copper (8.9 mg/kg) and zinc (9.5 mg/kg) corresponded to the MPC.

The article analyzed the possibility of using saponite as an ameliorant. In a model experiment, the effect of saponite on soil acidity, the content of biogenic elements (nitrogen, phosphorus, potassium), and productivity were studied. We found that introducing various doses of saponite does not affect the accumulation of water in the soil. It does not play the role of a deoxidizer and does not saturate the soil with nutrients, but prevents the removal of mobile nitrogen and potassium from the soil. Saponite does not increase soil productivity, but can affect the green mass productivity.
