“…The Department of Soil Science and Agrochemistry of the St. Petersburg State Agrarian University (Russia), together with the Agrophysical Research Institute (St. Petersburg, Russia) has been dealing with the problem of using non-traditional chemical ameliorants (local lime materials and industrial waste) for liming acidic soils (Litvinovich et al, 2001(Litvinovich et al, , 2013(Litvinovich et al, , 2016(Litvinovich et al, , 2017(Litvinovich et al, , 2018(Litvinovich et al, , 2019a(Litvinovich et al, , 2019b(Litvinovich et al, , 2020Pavlova et al, 2019aPavlova et al, , 2019cPavlova et al, , 2020Lavrishchev et al, 2017). The widespread use of these materials is limited by the presence of harmful impurities in their composition that can have a negative effect on soils and plants.…”

The waste slag materials from metallurgical plants contain calcareous materials, such as blast furnace (BFS) and converter slags (CS) of the Chelyabinsk Metallurgical Plant. However, the widespread use of these materials is limited by the presence of harmful impurities in their composition that can have a negative effect on soils and plants. The aim of our research is to study the effect of liming of soddypodzolic soils with metallurgical slags on the pHKCl value and the composition of the wash water. In a model experiment on columns, the migration ability of alkali metals from soils of light granulometric composition was studied after using two phases of steelmaking waste as a lime material. Research results indicate that the ameliorative properties of BFS and converter slags were different. When liming with BFS slag, a month after composting, the pHKCl value increased to 5.1 units. Studied soil from the category of "strongly acidic" moved to the category of "weakly acidic". When liming with the converter slag, the pHKCl value of the soil increased from 4.1 to 4.7 (the soil from the "strongly acidic" category moved to the "medium acidic" category). With an increase in the period of washing, the pH of the infiltration water increases. In the treatments with the use of BFS slag this increase was higher due to the continuing dissolution of ameliorants and the higher chemical activity of BFS slag. The liming led to intensive migration of alkaline earth metals. In the treatments limed with more soluble (chemically active) BFS slag, calcium losses were higher. Empirical estimation of alkaline earth metals leaching from the soil allowed to model the dynamics of the base migration. The dynamics of Ca and Mg migration from the soil were fundamentally different (content of Ca decreased, and of Mg increased). The dynamics of Ca migration from the soil limed with converter slag was most pronounced in comparison with the Ca dynamics for BFS slag and the Mg dynamics in all treatments.

“…The issues of fluorine translocation from soil to plants are quite fully covered in the literature (Pickering, 1985;Elrashidi and Lindsay, 1986;Trigub and Poznyak, 2008;Jha et al, 2009;Mourad et al, 2009;Tayibi et al, 2009;Perez -Lopez et al, 2010;Smidt et al, 2011;Tandelov, 2012;Lakshmi et al, 2016). However, the analysis of previous studies shows that a single opinion on the accumulation of fluorine in plants depending on its content in the soil, especially in the reclamation of phosphogypsum, has not been developed and is now controversial.…”

The materials of long-term research of the features of the content and distribution of fluorine in southern chernozems are highlighted. The purpose of this work is to investigate the effects of irrigation and chemical meliorants on the fluorine accumulation in soils and crops. To achieve this goal, the following tasks were set: to determine the content of fluorine in soils and plants in conditions of irrigation and application of phosphorus fertilizers (phosphogypsum); to carry out ecological assessment of southern chernozems in terms of accumulation and migration of fluorine in soil, plant resistance to fluorine accumulationand translocation. The research was conducted within the irrigation areas of Odessa region. Bulk and movable forms of fluorine were determined by the potentiometric method in the southern chernozems of different reclamation state (non-irrigated, irrigated and irrigated reclaimed). The content of movable fluorine in agricultural plants was determined by the author’s method. It was established that the contest of bulk fluorine is the highest in the non-irrigated chernozems, but does not exceed the MPC. In irrigation, the number of bulk forms of fluorine decreases due to their dissolution and migration from the top layer to the depth of the soil profile. The content of soluble forms of fluorine increases significantly in all components of agrolandscape under the influence of irrigation and especially the introduction of phosphogypsum. It was determined that the combined application of phosphorous fertilizers and manure leads toa decrease of the fluorine content in soils, lysimetric waters and agricultural plants. The degree of mobility of fluorine compounds in the studied chernozems during irrigation and especially the introduction of phosphogypsum increases. The level of fluorine content in lysimetric waters and the coefficient of water migration correlate with its content in soils. A positive correlation was found between the fluorine content in the roots of maize, oats, wheat ear and soil while its absence between the content of fluorine in the stems and leaves. The introduction of mineral and organic fertilizers together enhances the ability of plants to absorb fluorine from chernozem soils. The active contamination rate for all tested plants is higher than one, which can cause their inhibition. When resuming irrigation of chernozem soils, there will be a need for increased doses of mineral, including phosphorus fertilizers. Despite the low solubility of fluorine compounds, conducted research has shown that irrigation and application of phosphogypsum significantly increases the soluble forms of fluorine, which can adversely affect the pollution of agrolandscapes and public health.

In a 10-year laboratory experiment on columns, the migration mobility of calcium remaining in dolomite-reclaimed sod-podzolic soil after harvesting crops was studied. A “fund” of calcium compounds capable of migration in years with average long-term, excessive and insufficient levels of moisture has been identified. It was found that an increase in the volume of drained moisture contributed to an increase in unproductive calcium losses. The higher the dose of dolomite and the smaller the particle size, the greater the eluvial calcium loss. It is shown that the bulk of the calcium capable of migration was removed from the soil at the initial stage of washing. During the entire study period, migration calcium losses after pea harvesting exceeded losses after mustard cultivation. Empirical dependences describing the loss of calcium from the soil produced by dolomite in a wide range of doses have been developed. Various variants of the experiment were ranked according to the scale of calcium losses. It is shown that over 10 years of observations, the maximum calcium losses as a result of migration were characteristic of the variant of the experiment produced by dolomite flour calculated from the full dose of hydrolytic acidity. Calcium losses from soil reclaimed by dolomite particles of 5–7 and 7–10 mm in doses equal to 3 and 5 Hc were less.Key words: sod-podzolic light loamy soil, soil moisture availability, chemical reclamation, eluvial calcium losses, empirical models of migration process.
