On the development of biological products based on microorganisms from permafrost

The development of phytostimulants based on bacterial cultures isolated from permafrost soils of Western and Eastern Siberia, which have a higher adaptive potential to the peculiarities of the climate and soils of Western Siberia, is an urgent task. At present, the issues of “green” agricultural technology, based on the minimum use of chemicals and the expansion of the use of drugs of biological origin, are being actively considered. However, they are not universally applicable in various agro-climatic zones. Their activity and efficiency is associated with the survival rate in the rhizosphere and rhizoplane of plants and can be significantly reduced when used in areas of risky farming, in particular in Western Siberia. According to the results of morphophysiological studies, it was revealed that during the pre-sowing treatment of seeds of spring soft wheat of the Grenada variety with binary mixtures of pure cultures of some bacterial strains isolated from permafrost soils of three regions of Siberia, an increase in adaptively important plant parameters is noted.
