Modern world and national agriculture came very close, and in some cases already uses the technologies relating to the Industry 4.0. In article some directions of use of agrarian innovations, in relation to agriculture of the Irkutsk region whose territory is located in a zone of risky agriculture are considered. Short characteristic of climatic and hydroweather conditions in which the agricultural complex of the region functions is given and an attempt to give an assessment of the prospects of use of the considered technologies is made. The description of the main directions of development of the new agrarian technologies capable to find broad application in agriculture of zones of risky agriculture is carried out. As the key directions of use of practices of new technological way are considered use of the sensors and agrosensors united by technology of the Internet of things in adverse for farming, conditions. For obtaining more general idea about these directions the basic principles of operation of the considered devices and technologies and also their use taking into account the existing ecological and meliorative complexes inherent in the Irkutsk region are dis- closed. Features of their application at all stages of growth and development of plants are considered and also when harvesting. It is noted that the most expressed economic effect of use of the considered technologies can take place at intro- duction of mineral and organic fertilizers and also when using means of protection of plants – herbicides, insecticides and fungicides. It is connected with much more exact determination of quantity of the used means and their local expense based on expeditious monitoring by means of sensors of amount of nutrients in the soil, volume of green material of plants and quantity of a chlorophyll, exact determination of contamination of grounds by weed plants and insects wreckers, etc.
