AB  - 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.

AB  - This paper presents field scouting of corn in order to determine the content 
of nitrogen in the green parts of the plants. The aim was to measure the vegetative 
index using two optical sensors by OptRx AGL Technology. The sensors are positioned 
at a distance of 3.5 m, individually observing five rows of corn. The sensors are 
designed and constructed to allow sensors to be moved in altitudes relative to the 
ground and the green part of the plant, adjusting is manual, so that the height of the 
sensor varies from 50 to 70 cm above the plants, or at 5 different distances for 5 cm 
shifts. The speed of movement of the tractor also varied. The measured vegetative index 
of the plants is correlated with the height of the sensor. It was noticed that the 
correlation exists, but that it does not significantly affect the mapping of nitrogen 
content.
