Summary: This study found that no-tillage systems and cover crop management can improve soil organic carbon, total nitrogen, available phosphorus, exchangeable potassium-magnesium, bulk density, soil penetration resistance, and substrate-induced respiration which serve as indicators of soil health. The combination of no-till and rye cover crops appears to be a promising technique for enhancing SOC and soil health in Andisols. The melanic index values suggest that the soil is fulvic Andisols with low degree of humification, indicating that the no-till with rye system can enhance SOC and soil health.

Summary: This study assessed the impact of Strip-till and No-till technologies on the labile fractions of soil organic matter and soil structure. Sensitivity indicators were identified to monitor changes in the labile fractions of soil organic matter over a short-term period.

Summary: The accumulation of soil organic matter (SOM) is crucial for the functioning of agroecosystems. However, the influence of soil properties and agricultural management practices on SOM dynamics is often overlooked. This study used a network of farm fields in the USA to assess the effects of soil properties and management variables on SOM, total organic carbon (TOC), and total nitrogen (TN). The results showed that poorly drained soil, tile-drained fields, high clay content soil, and high biomass crop rotations were associated with greater SOM, TOC, and TN.

Summary: This paper investigates the influence of organic matter on the properties of cement-stabilized soil, focusing on the influence weights and mechanisms of fulvic acid and humic acid. The unconfined compressive strength test and electrical resistivity test are conducted to explore the impacts of FA/HA values and curing time on the mechanical properties and microstructure of cemented soil. The research reveals the influence laws of FA/HA and curing time on the microstructure of cemented soil and establishes quantitative relationship equations between FA/HA and curing time and the properties of cemented soil.

Summary: Climate projection requires accurate understanding of SOC decomposition and its response to warming. This study provides direct evidence of the rapid turnover of lignin-derived phenols compared to slower-cycling components of SOC, and reveals that temperature mainly regulates lignin turnover while slow-cycling components are strongly influenced by mineral association. These findings suggest that warming may greatly accelerate lignin decomposition, especially in soils with weak mineral associations.

Summary: Large quantities of mineral phosphorus fertilizer applied to intensively cultivated organic soils can cause rapid build-up of this nutrient and result in P loss through subsurface tile drainage water. Utilizing drainage water management (DWM) can effectively mitigate these losses and is a potential strategy for P retention in organic soils.

Summary: Compared to organic rotation systems, perennial grain agroecosystems can increase soil organic matter and microbial activities. However, a more diverse perennial grain cultivation does not lead to higher microbial biomass and activities compared to monoculture.

Summary: This study investigated the role of nutrients, particularly C and N, released from litter decomposition of different tree species on enzymatic activity and soil organic matter stabilization. The study showed a strong correlation between enzymatic activity and the amount of dissolved organic carbon (DOC) released during litter decomposition. Different tree species also had an impact on the carbon and nitrogen content of soil organic matter.

Summary: The study reveals that despite increased application of nitrogen fertilizers and straw incorporation, the SOC sequestration rate in continuous paddy soils was only 0.021 g C kg(-1) yr(-1) over 37 years, while new paddy soils developed from uplands had a rate of 0.145 g C kg(-1) yr(-1, indicating a declining trend in SOC sequestration efficiency over time with rice cultivation.

Summary: This article proposes a framework for spatially-detailed mapping of soil organic matter (SOM) based on cross-wavelet transform (XWT), which addresses the challenge of remotely sensed SOM mapping in dryland regions. By extracting ecologically meaningful features from intra-annual vegetation and soil-related endmember records and integrating machine learning approaches, the framework provides more accurate and reliable estimates of SOM and improves understanding of land degradation neutrality in dryland systems.

Summary: The study found that abandoning agricultural land led to changes in soil hydrophobicity and humic substances structure, affecting the functional properties of the soil. Land use influenced the humification process of soil organic matter, while changes in water regime influenced the transformation direction of SOM.

Summary: Organic matter amendment is used to improve soil quality in agricultural and urban settings, including supporting local food production and reclaiming disturbed soils in urban regions. Compost and biochar had the greatest improvement on soil organic matter content, while biosolids had greater nutrient benefits. The application of organic matter amendments also improved chemical and physical soil quality parameters. However, there are still gaps in the literature regarding the effects of amendments in urban gardens, soil depth greater than 30 cm, and the persistence of soil organic matter.
