Improving the efficiency of the soil uncompaction by the cultivator-subsoiler through the use of digital systems for working depth control

The article presents the results of scientific studies of the soil state formed under the influence of machine-tractor units in intensive technologies of potato production. It has been established that the main anthropogenic impact that reduces the yield of this crop is over compaction of the soil in the root spreading zone which prevents the spread of the potato root system. The studies used a rheological model of the soil state, statistical methods for assessing processes during the operation of tools for deep tillage and digital maps of fields. To loosen the soil, it is proposed to use a subsoiler cultivator equipped with a digital depth control system which ensures the implementation of differentiated processing that minimizes the energy consumption during tillage.
