Summary: The results of this study suggest that the use of no-till (NT) can effectively mitigate soil organic carbon (SOC) losses during the conversion of grassland to arable land. However, the tillage method does not affect the SOC content in the subsoil layer.

Summary: This study investigated the influence of long-term conventional tillage on the water-physical, chemical properties, and composition of chernozems. The results showed that tillage deteriorated the water-physical properties of the soil and affected the organic matter composition. The study also found that long-term plowing decreased aliphatic structures and increased aromatic structures in soils. To improve soil fertility and carbon sequestration potential, it is important to implement conservation tillage practices and prevent degradation processes.

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: This study examined the impacts of minimum tillage and no-till systems on soil organic carbon (SOC) levels in the inland Pacific Northwest region of the USA. The results showed that no-till did not result in higher SOC levels compared to minimum tillage. Therefore, judicious tillage can be considered as an option for sustainable production.

Summary: The study found that the stabilization of C in the surface soil layers of long-term no-till systems is affected by the C saturation deficit in MAOM, as well as the quality of the added litter. When the C stabilization in MAOM is low, C tends to accumulate in relatively stable forms in labile and intra-aggregate fractions.

Summary: The aim of this study was to understand the impact of the combination of no-till and cover cropping on soil organic carbon (SOC) and soil respiration. The results showed that for soils with high initial SOC contents, there was no significant difference in SOC and respiration between the conservation practices and conventional practices. However, for soils with low initial SOC contents, the conservation practices significantly increased SOC and respiration.

Summary: The study found that repeated sorption of identical DOM solutions led to a stabilization in MOM formation efficiency, while depletion of high-affinity compounds further decreased MOM formation efficiency. Although continued exchange between DOM and MOM molecules altered the composition of DOM, it did not impact MOM formation efficiencies. The interactions between the sorptivities of DOM components and mineral surface chemistry explain the legacy effects that regulate fluxes and distribution of organic matter in the soil.

Summary: Soil organic carbon sequestration is a promising method for mitigating climate change, and the formation of mineral-associated organic carbon (MAOC) plays a crucial role. Previous studies have suggested that the ability of soils to accumulate MAOC is limited by the amount of clay and silt particles. However, our analysis of soil samples from different land uses found that there was no detectable upper limit of MAOC content, challenging the notion that soil texture is the main limiting factor. Additionally, we observed a negative correlation between C content in the fine fraction and fine fraction content, further questioning the existing understanding of MAOC accumulation.

Summary: No-till is a top soil conservation practice, but may need enhancement as a carbon sequestration strategy. Companion practices such as increasing cover crops and crop rotation complexity can boost no-till performance and sequester more carbon in the soil.

Summary: The application of calcium- and magnesium-rich silicates in soil can capture and store carbon dioxide while also stabilizing soil organic matter. This study found that adding finely ground silicate rock mining residues to soil increased soil pH, inorganic carbon content, and soil-exchangeable calcium and magnesium. Furthermore, it increased mineral-associated organic matter by supplying secondary minerals and associated sites for organic matter sorption. However, the effect of silicate rock on microaggregates and carbon within was counteracted by the presence of plants, which decreased soil-exchangeable magnesium and calcium contents.

Summary: This study examined the accumulation of SOC in different tillage systems for over 34 years and found that no-till farming does not increase SOC stocks near the surface, but does increase with cumulative depth compared to moldboard plow. Results also indicate that deep soil sampling can affect conclusions about tillage system impacts on SOC stocks.

Summary: This study reviewed the mechanisms affecting SOC stability in NT systems, including priming effects, molecular structure of SOC, aggregate protection, association with soil minerals, microbial properties, and environmental effects. NT improves macro-aggregation and lowers SOC mineralization compared with CT. Chemical protection and higher microbial activity in NT contribute to SOC stabilization in the long term.

Summary: Soil carbon sequestration (SCS) refers to the uptake of carbon from the atmosphere and its storage in soil, with soil microbial community (SMC) playing a crucial role. Agricultural practices that improve SCS can alter SMC, soil organic matter, and soil aggregates. However, more research is needed to fully understand their contribution to SCS.

Summary: This study aimed to investigate the effects of labile organic carbon (LOC) input on the turnover of soil organic matter (SOM) in subtropical forests. The findings showed that LOC input reduced the priming effects of SOM decomposition and aided carbon storage in the soil.

Summary: This study developed and tested a soil conditioner based on APTES-modified LHS, showing improvement in soil structure and water stability with increased microbial activity and plant survival. Experimental results support the successful use of APTES-modified HS as a soil amendment, suggesting the formation of extended siloxane networks as the main mechanism for the observed improvement in soil structure.

Summary: The experiments investigated the leaching of copper(II) during soil washing with ultrafresh water under salinity pulsing, finding that the destruction of soil aggregates led to the leaching of copper(II) from soddy-podzolic soil, which was more resistant to damage compared to typical chernozem. It was concluded that leaching models for copper(II) should take into account the dissolved organic matter for soddy-podzolic soil and the content of aromatic fragments in the organic matter for typical chernozem. A conceptual model for Cu(II) leaching during soil washing with fresh water under salinity pulsing was developed.

Summary: The study examined the impact of thermochemolysis conditions on the fatty acid composition in soil, revealing that an excess of derivatizing agent at high pyrolysis temperature can decrease yield and relative abundance. Optimal conditions for assaying fatty acid content were found to be within the temperature range of 300-500 degrees C and 15-40 mmol/g C TMAH. It was also determined that the time of soil exposure to TMAH before analysis does not affect the results of thermochemolysis.

Summary: In this review, the changes in Fusarium taxonomy with the development of microbiological methods are described, including the ecological traits of this genus and the identification methods in soils, particularly for the detection of phytopathogenic representatives of Fusarium and their mycotoxins. The negative effects of soil-borne phytopathogenic Fusarium on agricultural plants and current methods for its control are discussed. Integrated approaches for the risk assessment of Fusarium diseases are necessary due to the complexity and polymorphism of Fusarium species.

Summary: Layers were removed from macroaggregates of Protocalcic Chernozems through successive abrasion, and the effects of particle size and processing time on organic matter quality and molecular structure were investigated. The results showed that particles with 0.5 mm size processed on the rotator for at least 10 hours exhibited favorable properties. In addition, clear differences in organic matter quality and molecular structure were observed between the peripheral and inner parts of the aggregates of the unmanaged fallow.
