“…This would result in slower decomposition of the residue and, therefore, a slower SOC mineralization rate (Cui, Li, & Wang, 2017). Similar results have shown that buried crop residue could effectively supplement subsoil soil carbon and nutrients (Hu, Shi, Wang, Gu, & Zhu, 2019;Zhou et al, 2018). In addition, using ploughing tillage can effectively improve the amount of available soil nutrients at depth, as our study observed with higher SOC and N storage in the 20-40 cm soil layer in PZT compared with ZT.…”

“…However, in a 4‐year experiment, Wang et al (2015) confirmed that burying residue into the upper 20 cm of soil can effectively increase soil C and N reserves, and it is a more efficient use of residue C and N than mulching. Zhou et al (2018), based on a 17‐month study, showed that approximately 17–20 cm was an suitable burying depth, and that when residue is buried at this depth, plants can use the nutrients present in the crop residue more effectively.…”

In residue return farming, ploughing and zero‐tillage (syn. no‐till or minimal tillage) rotation may regulate soil physicochemical properties and help reduce erosion and improve productivity; however, the soil physicochemical properties and soil productivity response to ploughing and zero‐tillage rotation remain unclear. This present study evaluates the effects of ploughing and zero‐tillage rotation on soil physicochemical properties and crop productivity based on an 11‐year experiment (2007–2018) on a typical erodible area of the Loess Plateau. Three tillage methods were included: ploughing and zero‐tillage rotation with 1‐year ploughing tillage and 1‐year zero tillage (PZT), ploughing tillage with moldboard plough (PT), and zero tillage (ZT); crop residue was returned in all treatments. After 11 years' we tested, the PZT method showed significantly lower soil water storage in key maize growth stages, less soil organic carbon (SOC) and total nitrogen (N) storage (0–10 cm), and poorer soil structure stability (0–10 cm) when compared with ZT. However, PZT showed significantly higher SOC and N storage (4.5%, 6.5% and 16.3%, 8.6%, respectively) in the 10–20 cm and 20–40 cm soil layers, compared with ZT. In addition, when compared with ZT and PT, PZT significantly decreased soil penetration resistance in 0–10 cm, 10–20 cm, and 20–40 cm soil depths and significantly increased yield of maize by 10.9 and 7.8%, respectively, and of wheat by 11.2 and 9.8%, respectively. This study highlights that combining ploughing and zero tillage with return of crop residue changed soil physicochemical properties and can provide an effective method to improve soil productivity in an erodible field.

“…Straw interlayers significantly increased SOC contents in the present study, mainly due to exogenous organic material inputs with straw applications (Cong et al, 2019). Several studies demonstrated that straw returning to surface soils at rates greater than 9 Mg ha -1 could not increase SOC (Zhou et al, 2018), while straw deep returning as interlayers at rates of 12-18 Mg ha -1 increased SOC content in the third and fourth year after the treatments in this study. The contrasting results are probably because of the differing straw placement in these studies.…”

Soil salinization is a critical environmental issue restricting agricultural production. Straw deep returning as interlayer (40 cm) has been a popularized practice to alleviate salt stress. However, the legacy effects of straw interlayer associated with the straw input amount on soil organic carbon (SOC) and total nitrogen (TN) in saline soil remain unclear. Therefore, a four-year (2015-2018) field experiment was conducted with four levels (i.e., 0, 6, 12 and 18 Mg ha ) of straw returning as interlayer. Compared with no straw interlayer (CK), straw interlayers increased SOC content by 14-32% and 11-57% in 20-40 cm and 40-60 cm, respectively. Lower increases were for soil TN content (8-22% in 20-40 cm and 6-34% in 40-60 cm) than SOC content, which led to increase soil C:N ratio in the 20-60 cm soil depth. Compared with CK, remarkable increases of SOC and soil TN contents in 20-60 cm led to the decrease of stratification ratios (0-20: 20-60 cm), which promoted uniform distributions of SOC and TN in soil profiles. Even though soil parameters ranged widely according to the straw input, straw interlayer with 12 Mg ha had higher SOC, TN, C:N ratio, and lower soil stratification ratio in 2015-2017, which contributed to salt leaching, water retention, and yield increment. These results highlighted the legacy effects of straw interlayers maintained more than four years, which led to an underestimation for previous short-term experiments, and demonstrated a great potential for subsoil fertility and salt-affected soil amelioration.

Heilongjiang province has made great contributions to ensuring the food security of China. Grain production has increased year by year, followed by a large amount of straw—especially the production of corn straw. Straw returning is the best treatment method from the perspective of ecology. This study simulated modern mechanized operation conditions from the field of soil biological characteristics to explore the impact of straw decomposition on the changes in the soil microbial community. In this study, in the black soil region of Northeast China (45°45′27″~45°46′33″ N, 126°35′44″~126°55′54″ E), the orthogonal experimental design was used to experiment for two years (2019–2020), using straw length, amount, and buried depth as returning factors. The carbon source utilization intensity algorithm that was developed by our team was used to extract a single carbon source. A compound mathematical model was constructed based on path analysis and grey relation analysis. This study analyzed the interspecific symbiotic relationship of soil microbes in the process of straw returning and explored the regulatory methods and schemes with which to promote straw decomposition. The results showed that in the first year after straw returning, the cumulative decomposition rate of straw could reach 55.000%; the supplement of the carbon source was glycyl-l-glutamic acid, which was helpful for the decomposition of straw. It was found that cyclodextrin should be added within 90–120 days after straw returning to promote decomposition. In the second year of straw returning, the cumulative decomposition rate of straw can reach 73.523% and the carbon sources α-d-lactose and d-galactonic acid γ-lactone should be supplemented appropriately to promote straw decomposition. This study provides an experimental basis for corn straw returning to the black soil of the cold regions, along with the scientific and technological support for the sustainable development of agriculture and a guarantee of national food security.
