“…Others suggest that the physical effects of subsoiling do not usually last more than 1–2 years, after which the plow pan reappeared 27 . Our previous study has demonstrated that rotary tillage after subsoiling with an interval of two years contributed to enhancing GY and water use efficiency (WUE) 2,28,29 . However, studies on interval subsoiling tillage regime have focused mainly on the soil moisture content, nitrogen accumulation and translocation and the accumulation of dry matter under irrigated conditions in the 3HP 2,28,30 .…”

Excessive tillage and soil compaction threaten the sustainable farmlands in the Huang-Huai-Hai Plains of China. Our study explores tillage practices to improve soil and root ecology and promote productivity in the winter wheat fields. We tested the impact of plowing, rotary, strip rotary tillage and strip rotary tillage with a two-year subsoiling interval (SRS) on wheat yield and root quality. SRS decreased soil bulk density compared with other treatments, resulting in lower soil penetration resistance. Root morphology and weight density decreased with the increased soil depth and was higher in SRS. Moreover, SRS increased the indoleacetic acid and trans zeatin riboside levels corresponding to greater TTC reduction activities, the total and active absorption root area. SRS increased the superoxide dismutase and catalase activities and soluble protein concentration and decreased the malondialdehyde concentration. The first two factors extracted using 11 root attributes in various soil layers through principal component analysis were selected as the integrated indicators for the minimum data set, and their integrated score was calculated to quantify the root quality. Our study suggests that SRS could significantly improve root morphology and enhance the root activity in subsoil layers, thus, delaying root senescence and increasing winter wheat yield.

“…In fallow studies, subsoil is considered only in the case of subsoil remediation and when comparing soil layers (Chintu et al, 2004; Gill et al, 2012; Gregory et al, 2016). Subsoiling, which is a general tillage method in northern China (He, Shi & Yu, 2019), will be applied in our study farmlands. Therefore, it is necessary to study the subsoil to improve the soil quality.…”

Fallow management can improve the soil nutrients in the topsoil and upper subsoil. However, little is known about the effects of short-term (one year) fallowing with different treatments, such as vegetation and fertilization, on subsoil (20–40 cm) properties. We conducted field trials to explore the changes in subsoil properties in response to such treatments in the Yellow River Delta region in China. Different vegetation and fertilization treatments were applied, and we measured the carbon and nitrogen contents, microbial biomass and microbial community structure in the subsoil. Fallowing without manure resulted in the storage of more total nitrogen (16.38%) than fallowing with manure, and meadow vegetation improved the ammonium nitrogen content (45.71%) relative to spontaneous vegetation. Spontaneous vegetation with manure improved the microbial biomass nitrogen (P < 0.05). Although the impact of short-term fallowing on microbial community structure was low, an effect of management was observed for some genera. Blastopirellula, Lysobacter, and Acidobacteria Gp6 showed significant differences among fallow treatments by the end of the year (P < 0.05). Blastopirellula abundance was related to the microbial biomass nitrogen and nitrogen mineralization rate in the subsoil. Manure retained a high abundance of Lysobacter, which may strengthen soil-borne disease resistance. The response of Acidobacteria Gp6 showed that meadow vegetation without manure may not benefit future crops. Although the treatments did not significantly improve microbial community structure in the one-year period, annual fallowing improved certain subsoil properties and increased the number of functional genera, which may enhance crop productivity in the future.

“…Most of the soil physical and chemical properties were signi cantly affected by tillage disturbance. Previous studies have shown that the reason for the signi cant decrease in OM is that tillage improves soil aeration and break down soil aggregates to enhance microbial activity for decomposition (He et al 2019), thus OM degradation was accelerated. Moreover, ooding creates anoxic conditions and enhances Ca 2 -P phosphate and Ca 8 -P phosphate in soil, both of which are essential components of soil AP pool.…”

Understanding the effects of tillage on the community composition and diversity of bacteria and archaea is useful for the long-term sustainable utilization of black soil. In this study, non-disturbed virgin black soil (NDBS) in the past 60 years, and the adjacent black soil under the arable land farming (DFBS) and paddy rice (PBS) for 3 years were chosen to investigate the microbial characteristics and their relationship with physical and chemical properties. The microbial diversity was investigated using 16S rRNA genes high-throughput sequencing technique and its relationship with soil physic-chemical properties was analyzed by redundancy analysis. The diversity of archaea decreased significantly after arable land farming. After conversion from arable land farming to rice paddy, the diversity of bacteria increased significantly, while the diversity of archaea increased significantly. In DFBS, the available phosphorus increased significantly, yet pH, organic matter and available potassium decreased significantly. However, the pH and available phosphorus increased significantly, organic matter and total nitrogen decreased significantly in PBS. The soil pH had the closest correlation with the microbial diversity. These indicated that tillage disturbance changed the diversity of bacteria and archaea as well as physical and chemical properties in black soil.
