Abstract: In statistics, Siberian fir constitutes merely 0.02% of Mongolia's total forest resources. Illegal logging and human activities have led to a decline in fir forest resources and their distribution in recent years. Nevertheless, scientific studies focusing on the cultivation of Siberian fir are comparatively rare compared to other coniferous species. This study aimed to examine the effects of oxygen-rich nanobubble water irrigation on the seed propagation of Siberian fir and the feasibility of using this technology in Mongolia.
The use of oxygen nanobubble water enhances the height growth rate of Siberian fir seedlings by up to 20%. Therefore, the parameters of soil humus content, electrical conductivity, and pH exhibited positive results during the short-term experimental research of the growing season. Research must be continued throughout the growing season in tree nurseries using conifer plantations. 
With the support of the Canadian Embassy and GAIA Water LLC, this research study was funded by the BILLION TREE FUND (https://billiontree.mn/) of Mongolia.
