“…Conventional tillage showed a certain advantage with respect to maize yield, which was significantly higher than those with RT and NT. Under the conditions of NT and RT, the volumetric weight of the soil was large and the plow bottoms remained hard ( Hua, Guo & Zhang, 2008 ; Gong & Lv, 2014 ; Ma et al, 2014 ), while CT greatly disturbed the soil, which can break the plow bottom to a certain extent and increase the distribution of the root systems in deep soils ( Zhai et al, 2017 ; Wang et al, 2020b ), both of which are conducive to increases in crop yield. Nevertheless, while the yield of the CT treatment was high, the HI was significantly lower than those of the NT and SS treatments.…”

“… Zhang et al (2015) also found that crop yields increased under NT. Meanwhile, SS can break compacted hardpan layers, reduce soil strengths, improve water use efficiencies ( Wang et al, 2020a ; Wang et al, 2020b ), promote crop growth, and improve crop yields ( Jr & Aase, 2003 ). Some studies have shown that there is a significant positive correlation between maize yield and SOC content ( Xu et al, 2019 ), the latter of which can be directly affected by tillage methods.…”

“…Studies have shown that, compared to traditional tillage, conservation tillage (represented by less or no-tillage) can effectively improve the physical properties of soil, increase the water holding capacity, simplify operations, and reduce the mechanical input; therefore, it is widely used in practical production [6,45,46] . For example, in many arid and semiarid areas, no-tillage or shallow RT is adopted to prevent frequent and large-scale disturbance of soil [23,47] ; however, in some areas, tillage is adopted year after year to obtain higher yields or increased soil moisture content for sowing [48] . However, the disadvantages of the long-term use of a single tillage pattern have gradually emerged [15,49] ; for example, no-tillage in successive years causes the plough layer to become shallow, which restricts the penetration of the root system [50] .…”

“…This practice shows high potential for SOC preservation in the deeper soil layer and for prevention of carbon loss from the surface layer. Subsoil has high potential for the storage of additional soil organic carbon because of the large number of unsaturated mineral surfaces and environmental conditions that impede SOC decomposition, e.g., a more constant moisture and temperature regime or oxygen limitation [75]. Subsoiling can break compacted hardpan layers and it reduces soil strengths and improves water use efficiencies [75][76][77].…”
