[1] Efficiency of remediation of technogenic barrens around the severonikel factory on the kola peninsula / G. N. Koptsik, I. E. Smirnova, S. V. Koptsik et al. // Moscow University Soil Science Bulletin. — 2015. — Vol. 70, no. 2. — P. 78–84. The soil of the technogenic barrens formed under the impact of long-term air pollution around the Severonikel factory is acidic, depleted in nutrients, contaminated with heavy metals, and strongly eroded. Remediation by coating the topsoil with a fertile layer developed based on organic and mineral compounds is accompanied by decreasing the soil acidity and enrichment with carbon and nutrients (nitrogen, phosphorus, potassium, calcium, magnesium, manganese, and zinc). However, under the existing operational conditions, the surface layers of most treated soils accumulate nickel and, especially, copper. The efficiency of remediation depends on the composition and thickness of the constructed layer, as well as the related measures, which should be supplemented by repeated liming. [ DOI ]
