Microbiological diagnostics of soil stage in the phyllosphere of the woodland ecosystem of Siberia

Abstract

It is shown that the diagnostics of the stage of woodland soils affected by wildfires and forest cuts can be determined by the evaluation indexes of the range of the scale of abundance of typical ecologic and trophic groups of microorganisms (ECTGM), microbiological activity coefficients, reserve and abundance fluctuations, and metabolism. The degree of impact of the technogenic emissions on the forest cover, soil, and phyllosphere according to ECTGM abundance on the diagnostic environments and their fermentative activ ity is expressed with the help of an advisability functional relation.

Assessment of soil properties in technogenically disturbed lands of Kemerovo Oblast – Kuzbass

“…Phosphatase activity was expressed in mg P2O5 per 10 g of soil per 1 h. Soil respiration intensity under laboratory conditions was estimated according to the method described by N.D. Sorokin and E.N. Afanasova [17]. The method relies on determining the intensity of soil respiration by considering quantitative changes in the carbon dioxide content in a certain enclosed space using wide-necked conical flasks.…”

Catalase Activity of Podzolic Soils in the Native Spruce Bilberry Forest and Deciduous-Spruce Forest Stands of Different Age

“…Из параметров биологической активности почв наиболее широко используются биохимические показатели, в первую очередь показатели ферментативной активности, поскольку почвы являются «каталитической матрицей биосферы» [2]. Наиболее информативны показатели активности ферментов, относящихся к классу оксидоредуктаз (каталаза, дегидрогеназа, пероксидаза, полифенолоксидаза) и классу гидролаз (инвертаза, уреаза, фосфатаза, протеаза), уровень которых четко отражает степень воздействия антропогенеза [1], в частности лесозаготовительной деятельности [3][4][5][6][7].…”
