Study of Reusability of Leaf Litter as a Sorption Material in Relation to Iron Ions

Tree Litter Production and Decomposition in Forest Ecosystems Under Background Conditions and Industrial Air Pollution

“…Quantitative and qualitative characteristics of tree litter are of practical interest for assessing the level of radiation pollution (Bondareva, Rubailo, 2016;Komissarov, Ogura, 2017), fire danger based on the accumulation of combustible materials (Arkhipov, 2014;Sobachkin et al, 2017), accumulation of heavy met-als by tree plants in urbanized areas (Kopylova, 2012). The use of tree litter debris, mostly coniferous or foliar, as a source of cellulose (Danilova, Stepanova, 2017), sorption material (Alekseeva, Stepanova, 2015;Silaicheva, Stepanova, 2016;Shaimardanova et al, 2017;Sverguzova et al, 2017), calcium fertilizer (Petrochenko et al, 2015) is being actively investigated. In mathematical studies, data on the input and decomposition of plant litter are used to form models for estimating the participation of litter in the biological cycle, the relationship with atmospheric CO 2 and climate (Brovkin et al, 2012;Mironenko, 2017).…”
