Abstract

The technologies for implementing the tasks of involving fallow lands in agricultural turnover and increasing the fertility of agricultural lands in the long-term period of economic activity are highlighted. Insufficient informativeness of the use of yield maps to assess the fertility of fields has been revealed. It is proposed to use field relief maps to establish the dynamics of violation of the water-air regime of the soil. It is proved that in the process of involving fallow lands into circulation, it is necessary to introduce a technological operation of microtopographic analysis of the degree of soil moisture. An algorithm for enabling the operation of levelling of field surface (removal of relief) using modern positioning systems has been developed. It was revealed that the levelling of the field with a laser level allowed to reduce yield fluctuations by 20% within the crop acres of the field and increase yield by 25-30%. Disadvantages of positioning accuracy with the use of laser and satellite positioning have been established. It is proposed to transfer digital information transmission modules to network clusters with the choice of the best digital data transmission channel by including an uninterrupted positioning module with digital data transmission over a 434 MHz and 864 MHz radio channel with a range of up to 600 meters to other modules for providing digital positioning information to the machine. The plan of implementation of the concept of digital field formation on the basis of the field experimental station of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy is presented, with the aim of creating a frontier for the sustainable development of closed-life cycle technologies through the introduction of innovations using multiplicative interaction of mechatronic systems and telematics for agricultural technology.
