Summary: The study revealed that soil organic carbon (SOC) content in the Guanzhong Plain decreased significantly with soil depth in the upper 100 cm layer, while it remained relatively low and stable in deeper soil layers. Unlike in the upper layers, SOC in deep soils was primarily influenced by soil properties. Changes in agricultural land use did not significantly impact SOC in both shallow and deep soils of the study area.

Summary: This study compared the effects of different land use management practices on soil organic matter (SOM) composition and found that conservation tillage methods (such as no-tillage and ploughing) were more similar to the soil in tree ecosystems, while conventional tillage methods were different. The study demonstrated that land use can alter the structure and stability of SOM compounds.

Summary: Compared to virgin land, croplands have lower organic carbon storage due to soil tillage and decreased plant inputs. Cover crops grown in-between crops appear to be the most effective method for increasing cropland organic carbon stocks. However, existing studies have limitations and more research is needed for better design and understanding.

Summary: Soil organic carbon (SOC) stocks have significant impacts on climate change, sustainable agricultural development, and environmental management. This study aimed to propose a conceptual framework and quantify the influence of land use change (LUC) and agricultural management practices (AMPs) on SOC stocks. Using a Kriging-based spatial prediction model, SOC stocks were estimated based on field sampled soil data (0-30 cm depth) in 2005 and 2019. Film mulching, drip irrigation, and fertilizer application were chosen as representative AMPs for the region. Results show that SOC stocks increased by 12.7% in the Sangong river basin from 2005 to 2019. The proposed conceptual framework reveals that transitions between land-use types may cause both losses (e.g., -9.49 Gg C from expansion of construction land) and gains (e.g., +3 Gg C from conversion of cultivated land to grassland) in SOC storage. Improved AMPs, such as film mulching, drip irrigation, and fertilizer application, contribute the most (+36.0 Gg C) to the growth of SOC stocks in the stable cultivated land category.

Summary: This study investigates the impacts of land-use change on soil organic carbon (SOC) and nitrogen stocks in North-West Ethiopia. It finds that conversion of natural forest to grazing and cropland leads to significant depletion of C and N stocks. However, eucalyptus plantation shows potential for soil C recovery. The study also highlights the importance of considering the quality of SOM when assessing disturbance impacts on SOC and N stocks.

Summary: Hydrology plays a crucial role in the degradation of emerging organic contaminants in soils. This study investigated the removal and degradation of five organic contaminants under different soil organic matter contents and flow conditions. The results showed that soil saturation and organic matter content can significantly affect the removal and degradation of organic contaminants.

Summary: Almond hulls and shells applied as soil surface amendments can rapidly release potassium, increase soil exchangeable potassium, and improve tree potassium status. This practice helps to recycle potassium, reduce orchard potassium fertilizer demand, and minimize associated costs.

Summary: Research shows significant differences in chlorination rates among soils with different types of organic matter, with forest humus layers exhibiting the highest Clorg formation rates. Chlorination rates decrease rapidly with depth in grassland soils, while agricultural soils exhibit relatively low chlorination rates along the entire depth profile.

Summary: The study evaluated changes in soil erosion and SOC contents under three different land use types in a dry-hot valley in southern China. Results showed significant impacts of land use types on SOC and TSN contents, with forest land having the highest values. The interaction between soil erosion and land use significantly influenced SOC variability in the soil surface layer.

Summary: The study evaluated the impact of alternative land-use systems and agricultural land-use systems on soil organic carbon and soil quality index in Goa State, India. The results showed that cashew had the highest soil organic carbon stock, and the ALUS system had higher levels of labile carbon, available nutrients, and biochemical properties. It is recommended to promote sustainable agriculture with ALUS on hills and AGLUS on coastal plains in Goa State to enhance SOC storage and improve soil quality.

Summary: By analyzing data from the China Rural Household Panel Survey, a panel logit model is used to investigate the effect of land certification on farmers' use of organic fertilizers. The findings demonstrate that land certification increases the likelihood of farmers using organic fertilizer by approximately 15%, with an average expenditure and amount of 35 yuan per mu and 23 kg per mu, respectively. This is primarily achieved by stabilizing farmers' expectations of property rights and enhancing the accessibility of agricultural subsidies. Additionally, the impact varies significantly depending on different production characteristics, property rights, and regional categorizations. Specifically, land certification is advantageous for small-scale farmers engaged in food crop cultivation, farmers with contracted land or lacking experience in land adjustment, and farmers in western regions, while it does not offer benefits to others. The study highlights the significance of land certification in improving cropland quality and serves as a reference for China and other developing countries.

Summary: This study evaluates the use of SOC/clay ratios as guidelines for soil management in England and Wales, suggesting threshold values to indicate soil structural condition. The index provides a method to assess and monitor soil organic matter based on easily measurable soil properties, with significant differences in soil organic matter levels observed across different land use types.

Summary: A meta-analysis conducted on 45 publications and 37 sites revealed that different ecological restoration practices have inconsistent effects on soil inorganic carbon (SIC) stocks. Conversion of cropland to forest and cropland to grassland had negative impacts on SIC stocks, while conversion of desert to cropland and desert to forest had positive impacts. Mean annual temperature, initial SIC stocks, and types of ecological restoration practice were identified as the most crucial factors explaining the variation in SIC stocks.

Summary: Farmers' participatory field trials were conducted in sloping lands of Meghalaya, India over 3 years to identify suitable agronomic management practices and input responsive rice genotypes for sustaining soil health and enhance carrying capacity of Jhum land. Improved Jhum practices significantly increased rice yield, improved soil health, farm profitability, and energy output. High yielding rice varieties outperformed local landraces in terms of yield. Therefore, it is recommended to grow high yielding rice varieties and adopt improved agronomic practices to achieve higher productivity and sustain soil health in Jhum ecosystems of north eastern Himalaya.
