In Serbia, there are about 400.000 hectares of heavy mechanical composition soil and over 100.000 hectares of soil damaged in various ways. Every year, with different degradation processes, new 1.000 hectares of soil are damaged. From the aspect of physical properties, soil compaction represents a serious problem that leads to changes in physical-mechanical and water-air properties and is one of the main factors of soil degradation. This paper presents the technique of measuring soil compaction on experimental field of 1 hectare using a hand-held penetrometer on operating depth 25cm, along with the geographic location of the sampling points. The data obtained in this research, the method of collecting, processing and displaying that data suggested certain shortcomings of the application of this method for testing soil resistance, as well as the need for a procedure for measuring soil resistance using a continuous method.

Seed plates of all seeding machines for widerow plants are powered by wheel of seeding machine and mechanical transmission. That has impact to volume and possibilitz of stearing.This paper show possibilities of using electromotor for power of seed plates as well as analysis possibylities acting stearing by electro system. In this paper are research measurement system and create stearing by programabil logic controller and shown idea for implementation steering of speed rotating of seed plates. That has aim to go about nominal seed space in row.
