Technologies and technic means of reclamation of fallow lands with regulation of the level of soil moisture

An assessment of the technological feasibility of the tasks of involving fallow lands in  agricultural  circulation  and  increasing  the  fertility  of  agricultural  land  in  the  long-term  period of  economic  activity  is  given.  Insufficient  information  content  of  the  use  of  yield  maps  for  assessing the  fertility  of  fields  has  been  revealed.  It  is  proposed  to  use  maps  of  the  relief  of  fields,  which  will allow establishing the dynamics of violation of the water-air regime of the soil. It is substantiated that in the process of involving fallow lands into circulation, it is required to introduce a technological operation of micro topographic analysis of the degree of soil moisture. An algorithm for switching on the field leveling operation (surface leveling of the field plane) using modern positioning systems has been developed. It was revealed that leveling the field with a laser level made it possible to reduce yield fluctuations by 20% within the cultivated area of the field and increase yield by 25-30% (an example of sowing corn). Shortcomings 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 digital information transmission modules of the vehicle positioning. A plan for the implementation of the concept of forming a digital field on the basis of a field experimental station of the RSAU-MAA named after C.A. Timiryazev, with the aim of creating a frontier for the sustainable development of closed life cycle technologies through the introduction of innovations using the multiplicative interaction of mechatronic systems and telematics for agro-industrial complex equipment.
