Claims (2)

1. A method of evaluating field compaction, including treating the field to the depth of the productive soil layer, characterized in that the field compaction is estimated by the amount of energy spent on decompression of the re-compacted and flooded soil, acting on it in the direction opposite to the process of compaction and swimming on a flat and ridged (crested) ) of the surface to its initial state, addition or profile, while the field compaction coefficient of the field (Coop) is defined as the difference between the decompression processing energies in the initial state (Ep ₁ ) and in compensated after the vegetation time and negative, including man-caused, impact (Ep ₂ ), referred to the unit of the cross-sectional area of the layer of the decompaction layer, taking into account the depth of processing (h) and the width of decompression (B) according to the formula

moreover, energy measurements of Ep ₁ and Ep _{2 are} carried out in the same places, the most unstable, critical for the field, and the number of measurements on the field is determined on the basis of heterogeneity of the surface shape, field configuration and soil mechanical composition, while the density factor of the group of crop rotation fields or any other group of fields is determined as the average value taking into account all the fields in the group, and the compaction energy is measured in the initial equilibrium, optimal state by preliminary preparation of the field and control measurement, in this case, the preparation of the field and control measurement are carried out at the same values of depth, processing pattern and speed of movement during processing with an interval between the preparation of the field and the control equal to the settling time of the soil loosened by the preparation of the field to its equilibrium state in density. 2. A device for evaluating the field compaction contains a frame with wheels and working bodies fixed on it, characterized in that the lancet cultivator legs for processing the upper active soil layer, chisel working bodies with inclined racks for loosening and decompression of the subsurface horizon are used as working bodies. spherical disks for restoration of the ridge (ridge) surface disturbed due to abundant watering of the soil and loss of its connectivity.
