Within the research project VEGA 1/0551/08 it was studied the agricultural impact on the soil with the use of penetrometer method at the production of spring barley (Xanadu, Ledi). This production had been done by usage of rationalization ways of tillage to ensure the efficiency of production and respect for ecological balance in the growing environment during three years research term. This paper evaluates the changes in the soil compaction in cultivation of selected new barley varieties in relation to the conventional and minimization techniques during this project and the previous six years. The measurements results showed the differences in soil compaction in monitored depths with better results for the conventional method of cultivation. Measurements indicated the benefits of reduced tillage particularly in connection with soil protection in the time of extremely low rainfall during the growing season. The use of minimization technologies can bring many business benefits to the agricultural sector. The most important is the saving of fuel, less labor needs, time saving and easier to manage the seed process in agro- technical terms. However, this technology is not for everyone. Term experience shows that by the usage of conventional tillage tend to be higher crop yields. Therefore in some years, when purchase prices significantly increase agricultural commodities, agricultural are returning to conventional technologies. Some cyclic changes had been found after long term study. Especially in the case of minimization technology is evident that there is a cyclic soil compaction in the deeper layers of the soil, which makes difficult access for plant roots to get to the soil moisture and so it reduce the intake of nutrients. This 3 to 4 year cycle is very clear and therefore it is necessary in those cycles of minimization tillage to plow up the fields what leads to improved access of water to the roots.
