Influence of nitrogen-fixing microorganisms on the growth of seeds of Scots pine (Pinus sylvestris)

The degradation of the soil cover, including the process of desertification is one of the most important environmental problems of our time. In Transbaikalia and the Pribaikalsky area, the area of desertification is the northern outskirts of a single sublatitudinal strip of desertification of Eurasia. The method of phytomelioration is the most suitable method for the ecological restoration of degraded lands. Also, nitrogen-fixing microorganisms play an exceptional role in restoring soil fertility. In this regard, the proliferation of nitrogen-fixing microorganisms in the surface layers of the soil of two key areas of the Selenga Middle Highlands has been studied. The accumulating cultures of nitrogen-fixing prokaryotes were used to study the effect on the seeds of scots pine. It was shown that complexes of cyanobacteria cells were most effective.
