“…On the other hand, the coefficient of variation of the soil preparation quality parameters presented an average of 19.70%. It can be associated with the variability of the physical attributes in the experimental area, as explained by Francetto et al (2021). The obtained results illustrate the difference in the operational speed over WS, ER, HCV, OS and PDB.…”

Operational speed influences the soil preparation quality, the first established according to the working set performance and its traction capacity. The experiment's objective is to determine the influence of working speed on energy and operational performance of an agricultural tractor with Full-Powershift transmission when performing a harrowing operation. We conducted the experiment using lines, in a randomized block design. It had four operational soil preparation speeds, with seven repetitions, totaling 28 experimental units. We measured the following parameters per worked area: slipping, engine rotation, specific and per hour fuel consumption, strength, power, and yield on the drawbar and operating speed. Additionally, we analyzed soil profilometry parameters concerning the mobilized area and working thickness. We also evaluated the variance of the collected data and, when significant, submitted it to a regression test. The data showed that higher operating speeds result in greater operational performance and reduction of the energy demand of the mechanized set under study. In addition, this increase doesn't have a beneficial effect on grid fluctuation, not affecting the quality of soil preparation.

“…Excessive open furrow forces of the furrow opener will cause excessive energy consumption. Excessive disturbance to the soil will reduce the soil backfill rate and inconsistent backfill depth, which will lead to excessive volatilization of liquid fertilizer, environmental pollution, and it will influence crop absorption [14][15][16]. The current working speed of the deep application machine of liquid fertilizer is typically limited to 6 km h −1 , and the high speed will cause excessive disturbance of soil and affect the effect of fertilization [17,18].…”

Coupled Bionic Design of Liquid Fertilizer Deep Application Type Opener Based on Sturgeon Streamline to Enhance Opening Performance in Cold Soils of Northeast China

Liquid fertilizer has many advantages, such as low production cost and little environmental pollution. Liquid fertilizer open furrow strip application method is widely used in fertilizer application operation. The widely used core-share furrow opener has a high operational resistance, disturbing the soil, hurting the crop roots, causing the liquid fertilizer to volatilize and deteriorating the fertilization effect. In this study, based on the streamline curve of the sturgeon body, we designed several bionic sturgeon liquid fertilizer deep application openers by combining bionics and analyzed the effects of several openers under different operating speeds on open furrow resistances and soil disturbance based on the discrete element method. The mechanism of open furrow resistances reduction and efficient soil backfill of the bionic structure were verified by indoor soil bin tests. The test results show that, compared with the core-share type furrow opener, both open furrow resistances and soil disturbance of the bionic sturgeon liquid fertilizer deep application opener are smaller. This study provides theoretical and practical references for the design of liquid fertilizer deep application openers.
