Резюме: In irrigated field conditions, the risk of negative changes in the physical parameters of the soil is more significant as the consequences are longer. Further more, the optimal physical condition of the soil is very limited due to the maintenance of a high level of pre-humidity.
From the conducted studies there was a deficiency of soil moisture after grading of barley and after rape seed formation of rapeseed. The results show that agro-technical measures only have a positive effect on the physical properties that are most dependent on the type of soil cultivation system applied. The bulk density is the physical parameter to maintain the values of which within the optimum boundaries requires a longer methodical approach. The overlapping in the 25 – 40 cm layer at the beginning of the experiment is partly overcome by loosening the soil to a depth of 35 cm. A deeper soil treatment is required to completely overcome the compaction.
It has been found that plowing of plant residues is important for maintaining higher humidity and for lowering the bulk density values of the Leptic Luvisols.
