“…Soil cone index is an empirical measure of soil shear strength (Chen et al, 2005; Osunbitan et al, 2005) and is widely used as a proxy for the ease of root penetration and for assessment of soil compaction (Bedard et al, 1997; Tessier et al, 1997). Cone index measurements were affected by tillage treatments during all five site‐years ( p ≤ 0.0254) based on the AUC approach (AUC C.I.…”

“…Subsoiling loosens the hardpan and breaks up deep, compacted soil layers without bringing the infertile subsoil to the top layer; and the effects last for up to four years 26 . 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 .…”

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.

“…Mechanical subsoil loosening (subsoiling) can be used to reduce soil strength beneath the plough layer, and has been shown by several investigations to increase root penetration (Marks and Soane, 1987;Hipps and Hodgson, 1988;Olesen and Munkholm, 2007). However, the physical effects of subsoiling often do not last more than 1-2 years, after which the plough pan must be reestablished (Hipps and Hodgson, 1988;Tessier et al, 1997). Our previous research has also shown that the 1-year subsoiling plus 2-years of strip rotary tillage helped to increase wheat yield and water use efficiency (Chu et al, 2010).…”
