Abstract
Through field experiments and empirical analysis methods, this study determined the dependence of plant residue removal on the row cleaner’s settings in strip-tillage. The main research object of this study is row cleaners. By changing the slip angles (10, 15, and 22.5°), the gap between row cleaner discs in parallel (165, 180, and 195 mm), and the driving speed (1.3, 1.9, 2.5, and 3.1 m s−1), we determined what percentage of wheat residue was removed from the strip on the surface of the soil and what distance it was moved. The percentage of removed plant residue was determined by evaluating the differences between the masses of the plant residue taken from non-removed and removed strips. Empirical analysis of the results of the field experiments showed that both the amount of the removed plant residue and the distance it is moved to were the best when the slip angle was 15°, the gap between the discs of row cleaner was 180 mm, and the driving speed was 2.5 m s−1. With these parameters, up to three-quarters of the plant residue was removed from the soil surface of the strip, which was relocated 308 mm from the middle of the strip. If the slip angle and the driving speed are increased further, even more plant residue can be removed; however, if the plant residue is relocated too far away, it may fall into the zone of the adjacent strip.

Tillage is a very important and expensive technological process involved in crop production [1,2].During soil cultivation, important processes of change are controlled in terms of the physical/mechanical and other characteristics of soil [3,4]
Similar trends have been noted by scientists from other countries performing similar experiments, who found that a driving speed of up to 2.8 m s−1 does not have a significant effect on the amount of plant residue removed [36,45]
Summary
Tillage is a very important and expensive technological process involved in crop production [1,2]. Important processes of change are controlled in terms of the physical/mechanical and other characteristics of soil [3,4]. Conservation tillage processes reduce the negative effect of tillage machines on soil properties including the erosion and compaction of soil layers, which results in the preservation of more natural water infiltration and better conditions for the penetration of crop roots [13,14,15]. By introducing conservation soil cultivation technologies, plant residue can be utilised as fertilizers and to protect soil from erosion, and fuel and crop management costs will decrease [16,17,18]
