Summary: This study assessed the long-term effects of biochar on soil organic carbon (SOC) accumulation through an 8-year field experiment. The results showed that the application of 3% and 5% biochar increased the content of macroaggregates, decreased the content of microaggregates, and significantly improved the stability of soil aggregates. Additionally, the application of 3% and 5% biochar had significant effects on SOC accumulation in all aggregate fractions, while the application of 1% biochar did not. These findings suggest that long-term application of 3% and 5% biochar is beneficial for enhancing SOC accumulation in clay loam soil and improving the stability of the soil carbon pool.

Summary: This study evaluated the impact of subsoiling depth on soil aggregation and SOC storage in the North China Plains. The results showed that subsoiling to a depth of 35 cm resulted in significantly higher proportions of macro-aggregates in the soil compared to conventional tillage depth. Additionally, subsoiling to depths of 30, 35, and 40 cm increased the mean weight diameter of wet aggregates in the soil by 39.5%, 57.7%, and 54.1% respectively, compared to conventional tillage depth. In the 0-40 cm soil layer, subsoiling to depths of 35 and 40 cm resulted in significantly higher SOC storage compared to conventional tillage depth, with increases of 12.7%, 18.5%, and 16.5% respectively.

Summary: Conservation agriculture (CA) is an important measure adopted worldwide to enhance soil organic carbon (SOC) for mitigating climate change. However, the impact of no-till and crop rotations, two principles of CA, on the protection of soil aggregates is still not fully understood. A field experiment conducted in the North China Plain showed that a legume-based no-till system significantly improved soil macro-aggregation, increased the conversion rate of straw C input, and reduced C loss.

Summary: Tillage practices have a significant impact on soil nutrient retention, soil structure, and stability. This study aimed to establish universal principles for soil stability and erosion resistance. Through field surveys and laboratory experiments, we found that different tillage practices had varying effects on soil stability and erosion resistance. No tillage was the most effective method for reducing soil erodibility, while subsoil tillage and soil compaction enhanced soil fertility and controlled soil erosion. This research provides valuable insights for selecting appropriate tillage methods in red soil hilly regions.

Summary: This study examined the effects of long-term low-phosphorus cropping systems in subtropical Queensland, Australia. It found that tillage practices and nitrogen fertilization did not significantly impact total phosphorus levels or various forms of phosphorus in the soil, but did result in pH changes and significant effects on soil organic carbon concentrations. While the use of no-tillage practices may increase soil organic carbon content in low-input soils, it does not necessarily lead to a concomitant increase in organic phosphorus, which is crucial for soil fertility and functioning.

Summary: Soil organic carbon (SOC) is an important indicator of soil health. In addition to SOC, other biological indicators can also provide information about soil carbon dynamics and microbial activity. This study examined the drivers of these indicators, their relationships, and the effects of soil health practices on indicator values. The results showed that the indicators were influenced by temperature, precipitation, and clay content. There were strong correlations among the indicators, especially between SOC and permanganate oxidizable C. Soil health practices such as reduced tillage and cover crop inclusion had positive effects on indicator values. The response to these practices was more pronounced in areas with higher precipitation. Based on cost, sensitivity, interpretability, and availability, a 24-hour potential C mineralization assay was identified as the most beneficial measurement to be conducted with SOC.

Summary: This study assessed the impact of physical disturbance on soil microbial communities and the potential carbon mineralization (Cmin). The results showed that the type of cropping system, the intensity of physical disturbance, and soil pH can influence microbial sensitivity to physical disturbance. The enriched sequences under soils managed with minimal physical disturbance were associated with organisms capable of producing extracellular polymeric substances and adapting to environmental stressors.

Summary: Soil carbon sequestration plays a crucial role in the sustainable development of agriculture. This study found that returning crop residue to the soil improved soil carbon sequestration capacity, but excessive residue mulching caused soil stratification, which was not beneficial for soil quality improvement. A strategic cultivation management mode that combines tillage and residue return can optimize soil management in a wheat-peanut rotation system and enhance soil carbon sequestration capacity.

Summary: This study used Discrete Element Modeling (DEM) to simulate the rupture of soil aggregates with different shapes but the same assumed distributions of cementing agents. The results showed that the Weibull modulus can be used to describe the heterogeneity of particle binding forces within the aggregate, and the sensitivity of this modulus to the heterogeneity of the binding force distribution increases with aggregate sphericity.

Summary: This study investigates the response of soil organic carbon (SOC) content to environmental factors in different soil layers in the Mollisol region of Northeast China. The results show that SOC content is primarily influenced by climatic factors, while soil properties play a significant role in the subsoil layer. Furthermore, geographical factors indirectly affect SOC content through their influence on climate factors, with mean annual temperature being the most important factor affecting SOC content.

Summary: Grass-clover leys in crop rotations on dairy farms can help mitigate climate change by sequestering soil organic carbon (SOC). However, accurately quantifying the SOC sequestration potential of grass-clover leys is challenging. This study found that grassland proportion and slurry C-input significantly influenced SOC storage based on a long-term experiment, and also demonstrated that soil nitrogen is stored along with SOC in equal proportions.

Summary: Tillage managements, especially subsoiling with straw residue incorporation, can improve soil aggregate microstructure and microbial community structure, leading to enhanced soil organic carbon (SOC) accumulation in the topsoil and subsoil layers. The variation in SOC within aggregates is primarily influenced by soil microbial characteristics rather than soil aggregate structure characteristics. Bacteria play a significant role in explaining the variation in SOC within aggregates. The interaction mechanism between pore characteristics, microbial structure, and SOC differs between the topsoil and subsoil layers, affecting the influx of organic C, pore size distribution, and microbial adaptability.

Summary: Soil organic carbon (SOC) is important for soil fertility, crop yield, and climate change mitigation. This study examined the effects of different tillage practices on SOC accumulation in paddy fields and its relationship with soil bacteria in southern China. The results showed that no-tillage (NT) increased rice residue carbon inputs, SOC content, and CO2 flux compared to reduced tillage (RT) and conventional tillage (CT). NT also significantly altered the soil bacterial community. The study suggests that the rapid increase in paddy SOC is influenced by both residue C input and the degradation functions regulated by soil bacteria.

Summary: Soil structure plays a crucial role in environmentally relevant soil processes, and the effects of freeze-thaw on soil structure depend on its preexistent strength and cohesion. Management choices such as tillage and plant cover strongly influence soil structure and its response to freeze-thaw. The study found that freeze-thaw caused crumbling of soil around coarse macropores, creating new very fine macropores and expanding previously indiscernible macropores.

Summary: The tillage and rice residue management practices have effects on the vertical distribution of microbial necromass and plant residues in rice paddy soils. The no-tillage (NT) practice resulted in higher microbial-derived carbon (C) in the soil, but did not significantly affect microbial-derived C contents and soil organic carbon (SOC) mineralization. However, it significantly decreased plant-derived C contents in the total SOC.

Summary: This experiment aimed to study the vertical and horizontal stresses during repeated wheeling from a lightweight autonomous robot and compare the measurements with calculations. The results showed a significant increase in mean ground pressure with repeated wheeling, measured values of maximum vertical stresses were 32% larger than the ones predicted by the model. These findings suggest that using static loads from this machine as inputs in models can result in inaccurate predictions of soil-tyre interface parameters.

Summary: The increasing size of agricultural machinery has led to increased risk of soil compaction. Lightweight autonomous robots have been proposed as a solution, but they may increase the area affected by traffic and repeated wheeling. This study evaluated the effects of load and repeated wheeling from a lightweight autonomous robot on soil physical properties. The results showed that load configuration and the number of passes both had significant effects on rut depth, apparent cohesion, penetration resistance, air permeability, and effective air-filled porosity.

Summary: This study investigated the correlation between different fractions of glomalin-related soil protein (GRSP) and fatty acid fractions in soil, as well as the impact of conservation agriculture practices on arbuscular mycorrhizal fungi (AMF) biomass and GRSP content. The results showed a positive correlation between easily extractable (EE) GRSP and phospholipid fatty acid (PLFA) 16:1 omega 5, indicating the complexity of GRSP dynamics and the need for further research. Additionally, mechanical soil management had a greater impact on AMF biomass and EE-GRSP compared to residue management, suggesting that tillage practices exert a stronger influence on AMF abundance and GRSP content than residue management.
