“…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 accumulation of fluorine in soils and plants during the application of mineral fertilizers was considered in the works of Kudzin and Pashova (1970), Piotrowska and Miacek (1975), Thompson et al (1979), Pashova (1980, Baranovsky and Pankrutskaya (1992), Kabata-Pendias and Pendias (1989), Loganathan et al (2001), Weinstein and Davidson (2004), Tandelov (2012), Trigub, Poznyak (2014), and others. Systematic application of phosphorus fertilizers and phosphogypsum in large doses causes an increase in fluorine content in chernozem soils (Trigub and Poznyak, 2014).…”

“…According to Piotrowska and Miacek (1975), Thompson et al (1979), Pashova (1980), Trigub and Poznyak (2008), Mourad et al (2009), Tandelov (2012) enrichment of soils with fluorine-containing mineral fertilizers leads to an increase in its content in crop yields. The relationship between the quantitative content of fluorine in soils and plants is defined in the works of Haidouti et al (1993), Davis (1995), Tandelov (2012), Trigub and Poznyak (2014). In climate changing conditions and the urgent need for irrigation of soils of the steppe zone of Ukraine, the problem of fluorine pollution of chernozem soils and agricultural plants is relevant and needs further study.…”

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.
