Title : Impact of the speed of cultivation units and cultivation and sowing units on the working resistance in the aspect of long-term use of different systems of soil cultivation
Key words : cultivation unit; working resistance; cultivation; speed of the unit
Summary :

Results of tests on working resistance of cultivation units and cultivation and sowing units used in various systems of soil cultivation. The objective of the paper was to determine the impact of speed of cultivation units and cultivation and sowing units on working resistance including diversity of previous cultivation systems. Properties of soil on the analysed fields, where different cultivation system was used, was characterised with the use of physical and mechanical properties of soil such as: moisture, compactness and maximum shear stress. Working resistance was determined for: a stiff tine cultivator, a disc harrow and a cultivation and sowing unit used in the direct sowing technology. Working depth was determined for all units as equal to 0.05 m. Measurements of working resistance were carried out with the use of two tractors connected with a haul, where strain gauge force transducer was mounted. Significant impact of the used unit and working speed was determined, whereas no impact of the previous soil cultivation system on the measured working resistance was reported.
