“…Soil density (BD) was determined by the ring‐cutting method. After obtaining the wet weight, soil samples were placed in a drying oven at 105°C to constant weight and then reweighed to calculate the soil water content (SW) (Zhang et al, 2022). Concentrations of available nitrogen, available phosphorus, and available potassium were measured using a Continuous Flow Analyzer (Analytical AA3 Auto Analyzer 3HR) after extraction with 0.1 M KCl, 0.5 M NaHCO 3 , and 1 M NH 4 OAc, respectively.…”

Soil organic carbon (SOC) mineralization is a process driven by microorganisms and is considered to be one of the main forms of carbon loss in land restoration. However, the interaction of SOC structures and bacteria that drive SOC mineralization remain unclear. Therefore, four forest succession stages were investigated on the Loess Plateau of Northern China: (1) primary stage Betula platyphylla (BP); (2) transitional stage which were two mixed communities of Populus davidiana and Quercus wutaishanica with different proportions (PQ1); (3) (PQ2) and (4) the late stage was climax communities of Quercus wutaishanica (QW). The Illumina sequencing of the 16S rRNA gene and Fourier transformation infrared (FTIR‐ATR) spectroscopy were used to clarify the regulation mechanism of microbial activity on SOC mineralization during forest succession through the perspective of SOC structures. Our results indicated higher aromatics‐C in QW contributed to decreased SOC mineralization ratio (SMR). Redundancy analysis confirmed SOC structures–bacteria interaction and revealed the groups Acidobacteria correlated with recalcitrant SOC structures while Proteobacteria and Bacteroides correlated with labile SOC structures, respectively. Moreover, the partial least squares path model revealed that the SOC and C:N ratio act on soil bacteria community characteristics, and the higher abundance of Acidobacteria and the increase of aromatics‐C decreased SMR. Collectively, these findings highlight the importance of bacteria–SOC structures interaction in decreased SMR and contribute to an improved understanding of how forest succession regulates carbon mineralization.

“…Xuan Yang [19], using APSIM (Agricultural Production Systems sIMulator)-based simulation modelling and data collected in Xifeng, Gansu, China, found that conservation tillage has better performance for soil water storage, reducing soil evaporation and reducing evapotranspiration, while only plant transpiration is greater compared with conventional tillage. Qi Zhang [20] conducted a long-term experiment in Ganjing, Heyang County, Shaanxi Province, China. This study showed that no-tillage reduced water consumption by 10.6% compared with conventional tillage over the entire growing season, and no-tillage could increase the water use efficiency as well.…”

In the context of climate change, agricultural cultivation, as one of the most vulnerable sectors, is under threat. Extreme weather and climate conditions have caused a series of problems, such as yield loss, more serious pests and diseases, and declining biodiversity. Conservation tillage is considered a potential method to improve climate resilience, yet the intrinsic mechanism of how conservation tillage functions to improve the climate resilience of agriculture is uncertain. Here, we performed document analysis to explore how conservation tillage stabilizes and increases crop yield and reduces greenhouse gases. We reviewed the definition of resilience and proposed the practice of conservation tillage. Our research found that conservation tillage has the potential of improving soil health and reducing greenhouse gases to enhance climate resilience. Although there is some evidence demonstrating that conservation tillage has a negative impact on crop yield and greenhouse gases, we still advocate the adoption of conservation tillage according to local conditions. We suggest that choosing proper practices, such as crop rotation, the use of cover crops, and holistic grazing, when used along with conservation tillage, can maximize the benefits of conservation tillage and alleviate the possible negative effects of this practice.

“…influenced, the edaphic conditions moderated by agronomic measures become the crux for depressing soil evaporation. Tillage practices with variable mulching options are favorable for the optimization of edaphic conditions (Naveen et al, 2021); therefore, they have been widely proposed to conserve soil water (Zhang et al, 2022). In this study, wheat uniquely received no-till with plastic film mulching (NT) from previous maize, which lowered soil evaporation during the wheat-growing season.…”

Excessive nitrogen (N) fertilizer has threatened the survivability and sustainability of agriculture. Improving N productivity is promising to address the above issue. Therefore, the field experiment, which investigated the effect of no-till and N fertilizer reduction on water use and N productivity of spring wheat (Triticum aestivum L.), was conducted at Wuwei experimental station in northwestern China. There were two tillage practices (conventional tillage, CT; and no-till with previous plastic film mulching, NT) and three N fertilizer rates (135 kg N ha–1, N1; 180 kg N ha–1, N2; and 225 kg N ha–1, N3). The results showed that NT lowered soil evaporation (SE) by 22.4% while increasing the ratio of transpiration to evapotranspiration (T/ET) by 13.6%, compared with CT. In addition, NT improved the total N accumulation by 11.5% and enhanced N translocation (NT) quantity, rate, and contribution by a range of 6.2–23.3%. Ultimately, NT increased grain yield (GY), N partial factor productivity, and N harvest index by 13.4, 13.1, and 26.0%, respectively. Overall, N1 increased SE (13.6%) but decreased T/ET (6.1%) compared with N3. While, N2 enhanced NT quantity, rate, and contribution by a range of 6.0–15.2%. With the integration of NT, N2 achieved the same level of GY and N harvest index as N3 and promoted N partial factor productivity by 11.7%. The significant positive correlation of NT relative to T/ET and GY indicated that improving T/ET was essential for achieving higher NT. Therefore, we concluded that no-till coupled with N fertilizer rate at 180 kg N ha–1 was a preferable management option to boost the N productivity of spring wheat in arid areas.
