Abstract (English):
The paper presents the data of agrochemical analysis of permafrost-meadow-chernozem soils of the site "Oi-Bes 2". Permafrost meadow-chernozem soils in Yakutia occupy the second place in terms of agricultural use. The main massifs of these soils are concentrated in the valleys of the Lena, Vilyui, Aldana, and Amga rivers. The research area is located in the adjacent territory of the village of Khatass of the city district "City of Yakutsk", located on the left bank of the Lena River. In Yakutia, in the soils on which agricultural crops are located, the humus content gradually decreases as a result of mineralization and removal of nutrients by plants, saline soils appear. The purpose of the work is to assess the state and dynamics of changes in the main agrochemical indicators of soil fertility. Methods: Industry standards: actual acidity (pH) GOST 26423-85, Tyurin method GOST 26213-84, Egner-Riem method (DL-method) GOST 26209-91, GOST 26951-86. Trace elements: Peiwe-Rinkisu GOST R 50684-94, Berger Truogu GOST R 50688
