“…In this study, the soil bulk density of each soil layer with subsoiling tillage (SF, RF‐S, and TP‐S) was lower than that of other treatments, and the soil porosity was higher than that of other treatments. This was consistent with the research conclusions of Zhang and Wang (Wang et al, 2021; Zhang et al, 2015). This is because the subsoiling operation breaks the plow layer, deepens the thickness of the soil plow layer, improves the soil structure, makes the soil loose and porous, and results in higher soil porosity (Gao et al, 2021; Li, Zhu et al, 2014).…”

Conventional tillage is still widely practiced in phaeozems sloping farmland, which leads to serious soil erosion. Adopting effective farming methods is crucial for mitigating soil erosion. To prevent and control soil and water loss in phaeozems sloping farmland, field experiments were conducted in 2022 using three tillage methods and their combination modes: subsoiling tillage (SF), ridge tillage and pitting field (RF), ridge tillage and pitting field + subsoiling tillage (RF‐S), contour tillage (TP), contour tillage + ridge tillage and pitting field (TP‐R), and contour tillage + subsoiling tillage (TP‐S). The study aimed to assess the impact these different tillage methods on soil and water conservation. The results showed that the contour tillage + ridge field treatment significantly reduced surface runoff and soil loss (p < 0.05), with no observed nutrient loss. Compared with other treatments, this method significantly reduced runoff, erosion, and nutrient loss. In contrast, the contour tillage + subsoiling tillage treatment significantly decreased the soil three‐phase R‐value, improved the soil texture, and exhibited higher yield, harvest index, and water use efficiency (WUE) compared to alternative treatments. Overall, the comprehensive findings indicate that contour tillage + subsoiling tillage can reduce soil erosion, enhance soil quality, and improve the WUE, all while maintaining high production capacity. Furthermore, the results of this study provide a theoretical basis for conserving soil and water resources, improving soil fertility, and increasing farmland yield in the phaeozems area of northeast China.

“…Therefore, long-term chemical fertilizer application significantly increased micro-aggregate content, improving the TOPC in micro-aggregates and their contribution to TOC in bulk soil. The reason was that micro-aggregates have a higher specific surface area, which could increase aggregates’ CPC ( Zhang et al., 2020b ). On the other hand, insufficient external organic carbon supply might promote the decomposition of SOC, which would then trigger the first decomposition of macro-aggregates combined organic carbon, lowering the TOPC in those macro-aggregates ( Mustafa et al., 2021 ).…”

Current research has long focused on soil organic carbon and soil aggregates stability. However, the effects of different long-term fertilization on the composition of yellow soil aggregates and the characteristics of the occurrence of organic carbon in the karst region of Southwest China are still unclear. Based on a 25-year long-term located experiment on yellow soil, soil samples from the 0–20 cm soil layer were collected and treated with different fertilizers (CK: unfertilized control; NPK: chemical fertilizer; 1/4 M + 3/4 NP: 25% chemical fertilizer replaced by 25% organic fertilizer; 1/2 M + 1/2 NP: 50% chemical fertilizer replaced by organic fertilizer; and M: organic fertilizer). In water-stable aggregates, soil aggregates stability, total organic carbon (TOC), easily oxidized organic carbon (EOC), carbon preservation capacity (CPC), and carbon pool management index (CPMI) were analyzed. The findings demonstrated that the order of the average weight diameter (MWD), geometric mean diameter (GWD), and macro-aggregate content (R0.25) of stable water aggregates was M > CK > 1/2M +1/2NP > 1/4M +3/4NP> NPK. The MWD, GWD, and R0.25 of NPK treatment significantly decreased by 32.6%, 43.2%, and 7.0 percentage points, respectively, compared to CK treatment. The order of TOC and EOC content in aggregates of different particle sizes was M > 1/2M +1/2NP > 1/4M +3/4NP> CK > NPK, and it increased as the rate of organic fertilizer increased. In macro-aggregates and bulk soil, the CPC of TOC (TOPC) and EOC (EOPC), as well as CPMI, were arranged as M > 1/2M +1/2NP > 1/4M +3/4NP> CK > NPK, but the opposite was true for micro-aggregates. In bulk soil treated with organic fertilizer, the TOPC, EOPC, and CPMI significantly increased by 27.4%–53.8%, 29.7%–78.1%, 29.7–82.2 percentage points, respectively, compared to NPK treatment. Redundancy analysis and stepwise regression analysis show that TOC was the main physical and chemical factor affecting the aggregates stability, and the TOPC in micro-aggregates has the most direct impact. In conclusion, the primary cause of the decrease in SOC caused by the long-term application of chemical fertilizer was the loss of organic carbon in macro-aggregates. An essential method to increase soil nutrient supply and improve yellow soil productivity was to apply an organic fertilizer to increase aggregates stability, storage and activity of SOC in macro-aggregates.

“…With the improvement of the level of mechanization in China, soil is gradually compacted due to the frequent operation of heavy agricultural machinery and tools in the farmland [1][2][3]. As one of the core technologies of conservation tillage, subsoiling practice has been employed to remove soil compaction and restore soil productivity [4][5][6][7]. Subsoiling technology mainly consists of natural, chemical, biological, and mechanical methods [2,8].…”

“…Additionally, less topsoil disturbance helps to conserve soil and reduce soil water evaporation [17][18][19]. The disturbance extent of soil at different depths often are used as an important indicator for subsoiler performance evaluation, and some studies have demonstrated that soil properties had significant effects on crop growth [6,16]. However, there are few reports on the variation and persistence of the impacts of soil disturbance amount at different depths (after subsoiling practice) with time.…”

Variation of Subsoiling Effect at Wing Mounting Heights on Soil Properties and Crop Growth in Wheat–Maize Cropping System

Subsoiling is an effective practice to promote better soil water infiltration and crop growth. The information regarding the variation and persistence of subsoiling effects with different soil disturbance on soil properties and crop growth was absent in previous research. In this study, the effects of wing mounting height (h) (75–155 mm) during subsoiling on soil disturbance at various layers, soil properties and crop performance were investigated using in situ field experiments from 2019 to 2021 in winter wheat–summer maize rotations. The experimental field soil was covered with crop stubble and crop straw was removed before subsoiling or sowing the next crop. The analysis of variance (ANOVA) was used to assess different subsoiling treatment effects on tested variables, including soil moisture content, bulk density, plant diameter, plant height, dry root weight, root number, yield, and yield components of crops. Means between subsoiling treatments were compared using Duncan’s multiple range tests. Based on ANOVA outputs, the h significantly (p < 0.05) affected soil moisture content in the first growing season of winter wheat (WW1), soil bulk density, number of roots and panicle number and grain yield of WW1, and thousand kernel weight (TKW) of both WW1 and summer maize (SM). Decreasing h overall gave better soil properties and crop performance. Decreased subsoiling effects were found on aspects of insignificant difference in subsequent grain yield of SM and winter wheat in the second growing season (WW2). These findings had implications for designing higher-performance winged subsoilers, as well as selection of subsoiling frequency.
