Abstract
The results of the study of the impact of phosphogypsum on the accumulation and migration of fluorine in the southern chernozems of the North-West Black Sea coast area of Ukraine are presented herein. It has been found that the introduction of phosphogypsum as a chemical ameliorator of irrigated chernozems resulted in a fluorine increase both in the soils and in the soil (lysimetric) waters.
Highlights
The results of the study of the impact of phosphogypsum on the accumulation and migration of fluorine in the southern chernozems of the North-West Black Sea coast area of Ukraine are presented
Phosphoric fertilizers contain the widest spectrum of concentrating chemical elements among standardized fertilizers
Fluorine and lead have the greatest concentrations in phosphoric fertilizers
Summary
The results of the study of the impact of phosphogypsum on the accumulation and migration of fluorine in the southern chernozems of the North-West Black Sea coast area of Ukraine are presented . It has been found that the introduction of phosphogypsum as a chemical ameliorator of irrigated chernozems resulted in a fluorine increase both in the soils and in the soil (lysimetric) waters.. Despite the sharp decrease in volumes and rates of introduction of mineral and organic fertilizers in the last decade, the degree of pollution of the soils of the southern chernozems of the North-West Black Sea coast area of Ukraine, which are intensively exploited in agriculture, remains high. Mineral fertilizers produce the greatest geochemical impact on soils and bioproduction of agricultural landscapes among main means of chemicalization [6, 13]. Phosphogypsum, which in addition to containing such elements of plant nutrition as calcium, phosphorus and sulphur, contains a great amount of admixtures, among which fluorine occupies a special place from the point of view of polluting soils and adjacent media, is widely applied in agriculture
