FLUORINE IN THE «SOIL-PLANTS» SYSTEM: ECOLOGICAL ASPECTS
Journal Title: Вісник Одеського національного університету. Географічні та геологічні науки - Year 2014, Vol 19, Issue 4
Abstract
Despite the significant distribution of fluorine in nature, great chemical activity of its compounds, the need for micronutrients to plant life is not determined uniquely. Does not exist also general views of researchers about the dependence of the fluorine content in the plants from its contents in the soil. In view of this very actual is the study of patterns of distribution of the fluorine in plants due to its content in the soil, and identifying the impact of irrigation and chemical reclamation on fluorine content in the «soil-plant» system. The object of the study were a different species of plants, the subject – the impact of fluorine on the growth and development of plants and the possibility of accumulation of microelement in the «soilplant» system under anthropogenic pollution. The aim of the article – to summarize scientific sources on the biological role of fluorine and its compounds possibility of accumulation in the «soil-plant» system. To achieve the aim were posed next tasks: a) to analyze the degree of knowledge of the problem, b) clarify the impact of fluorine on the growth and development of plants, c) establish the patterns of distribution of the fluorine in the «soil-plant» system, d) identify the impact of irrigation and chemical reclamation on active fluorine accumulation in plants. Conducted studies found that irrigation and putting of phosphogypsum leads to the accumulation of active fluorine in Southern chornozems and agricultural plants that can serve as an auxiliary source of income for animals and humans that from ecological point of view is extremely urgent problem.
