The spatial dynamics of soil mesofauna of Krasnoyarsk forest-steppe based on researching the farm “Minderlinskoe”

The great importance of invertebrates in forming soil fertility, the poor scrutiny of this issue in Krasnoyarsk region and in Russia, the high indicative value of soil mesofauna determine the relevance of studying conditions of mesofauna complexes of agrogenically transformed soils in dependence on their landscape position in the Krasnoyarsk forest-steppe. The experiment and the practical part were carried out in the period 2014-2016 on the territory of the UNPH "Minderlinskoe" belonging to Krasnoyarsk State Agrarian University which is situated in Emelyanovsky district of the Krasnoyarsk region. Mesofauna and soils of 940 meters long catena located at 55,8° n.l. were objects of the study. 4 positions: elluvially, trans-elluvially, trans-elluvially accumulative and trans-accumulative were selected in this catena. When accounting for soil mesobiota using the standard method of soil excavation, the change of mesofauna complexes in different landscape positions was discovered. Disturbance of zoocenoses structure tipical for agrogenic soils were noted.
