Summary: The long-term effects of no-till management on soil-profile compactibility are still unknown. Previous studies have mainly focused on the upper soil depth, limiting the understanding of compactibility changes at deeper depths. This study investigates the Proctor bulk density, maximum bulk density (MaxBD), critical water content (CWC), and their relationships with soil organic C (SOC) and mean weight diameter (MWD) for different soil depths in long-term tillage experiments. The results show that no-till reduces compactibility only near the surface, while disking reduces compactibility to deeper depths, suggesting that disk tillage may be more effective than no-till in reducing soil compactibility.

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: Aluminum toxicity is a crucial factor affecting crop yield in acid soils. Various techniques to measure exchangeable Al content in soil yield different results, with ICP-AES being the most accurate and efficient method. Application of dolomitic lime or calcium-magnesium silicate can effectively reduce exchangeable Al levels in the upper soil layers, and rotation crops can help improve soil Al availability.

Summary: The global potential for soil organic carbon (SOC) sequestration from 'no-till' (NT) adoption may be more limited than reported in some studies, with SOC gains concentrated in cool, humid temperate regions and minimal gains in the tropics. Further research is needed to improve understanding of tillage practices and their integration into land surface models (LSMs) for more accurate estimates of SOC sequestration from NT adoption, especially in tropical regions.

Summary: Earthworm activity and plant residues have a significant impact on soil organic carbon dynamics. However, the effects of different earthworm species on greenhouse gas emissions and soil organic carbon in different tillage systems are not well understood. This study investigated the impacts of two earthworm species on soil greenhouse gas emissions and organic carbon content in both no-till and conventional tillage soils. The results showed that earthworms increased CO2 and N2O emissions in both tillage systems, but the effects were more pronounced in no-till soils. Additionally, earthworms significantly increased the organic carbon content in no-till soils, but not in conventional tillage soils.

Summary: The increasing cost of fuel and machinery used in conventional tillage systems has made no-till management (NT) an attractive alternative for small-grain producers. However, applying fertilizers to the soil surface under NT could result in pH and soil acidity stratification. This study aimed to assess the soil attributes in the topsoil across different nutrient management levels in three long-term continuous NT wheat studies in the southern Plains of US. The results showed stratification of soil acidity parameters, with higher organic carbon and exchangeable aluminum and lower pH near the soil surface.

Summary: Potassium is a typical yield-limiting nutrient for soybeans in humid tropical regions. The study investigated the effect of fertilization on K balance in a highly weathered Rhodic Hapludox under no-till over 32 years of continuous cropping. It was found that K rates influenced yields over time, leading to either continuous K depletion or accumulation in soil depending on the rates.

Summary: Tillage and nitrogen fertilization have varying effects on soil properties in subtropical climates, especially in Vertisols. This study found that total organic carbon significantly increased with nitrogen fertilization under no-till practices. Total nitrogen concentrations were only influenced by nitrogen fertilization and not affected by tillage. Enzyme activity was affected by nitrogen application and tillage, but bacterial and fungal diversity remained unaffected. Overall, no-till and nitrogen fertilization are important for managing soil properties in this subtropical region, although the impact may be less pronounced over long-term trials.

Summary: We conducted a long-term nitrogen (N) fertilizer study to evaluate the effects of N rates on N losses, N use efficiency (NUE), and soil N content. The study found that NUE of harvested grain varied with N application rates, and the system N loss was mainly through nitrate leaching and atmospheric emissions. Additionally, the changes in soil N content were negative, indicating potential net N loss in the no-till system.

Summary: Recently, the eastern region of Maranhao state in Northeastern Brazil has seen significant land-use change from native vegetation to soybean cultivation. However, this change has resulted in substantial depletion of soil organic carbon (SOC) and nitrogen due to soil characteristics. Two factors, different timeframes after land-use change and contrasting soil management practices, were quantified to assess these impacts. The results showed that SOC stocks decreased by 35% after 8 and 15 years of land-use change, with a decrease in labile carbon and microbial carbon between 20% and 60% during the same period. When comparing soil management practices, no-tillage did not significantly affect SOC stocks, but both labile carbon and microbial carbon decreased by 15% with no-tillage and by 40% with mouldboard plough. These findings highlight the importance of adopting best agricultural management practices to preserve and increase SOC, reducing greenhouse gas emissions and promoting sustainability and profitability.

Summary: This study examines the carbon sequestration capacity of two dominant mangrove species, native Kandelia obovata and exotic Sonneratia apetala, in Qi'ao Island, China. The results show that both species act as strong carbon sinks compared to mudflat reference, with overall ecosystem carbon storage being comparable. However, the non-native species, Sonneratia apetala, exhibits a significantly higher carbon sequestration rate due to fast biomass carbon sequestration. The input of autochthonous source (mangrove tissues) contributes substantially to additional carbon sequestration under mangroves.

Summary: The expansion of agricultural areas worldwide due to growing demand for resources has led to poor soil management and soil physical degradation. This study investigated the effects of land conversion on soil physical properties in the Brazilian Cerrado region, including the conversion of native Cerrado vegetation to pasture and cropland. The results suggest that compaction processes equally reduced soil porosity in both pasture and cropland, but soil penetration resistance and stable mean weight diameter of soil aggregates were higher in pasture. The highest levels of organic carbon were observed in cropland, while the lowest levels occurred in pasture.

Summary: The expansion of sugarcane cultivation in areas currently occupied by low-productivity pastures has led to changes in soil structure and organic matter storage. This study investigated the impact of land-use change on soil organic matter fractions in two contrasting soil types and explored the correlations with soil aggregation and carbon stocks. The findings suggest that converting pasture to sugarcane can increase carbon stocks in clayey soils but decrease carbon stocks in sandy soils.

Summary: Adopting land-uses that contribute with a considerable litter input affects soil organic carbon accumulation and the physical fractions of soil organic matter. This study aimed to determine the impact of agroforestry systems on soil organic carbon content and physical fractions, as well as the influence of seasonality on the compartmentalization of soil organic matter. The results showed significant changes in soil organic carbon contents and physical fractions after a short period of implementing agroforestry systems, with the particulate fraction being particularly affected. The Carbon Management Index was found to be sensitive in detecting changes and revealed that the agroforestry system with the highest species density had the highest carbon accumulation in the soil.

Summary: Climate-smart agriculture (CSA) practices, including no-tillage, cover cropping, organic amendments, and crop-livestock and crop-livestock-forestry systems, have been widely adopted in Brazilian Cerrado and can contribute to climate change mitigation through soil carbon sequestration. A systematic review of 87 papers and 621 data pairs showed that all evaluated CSA practices resulted in average positive rates of soil carbon stock change, indicating soil carbon accretion after adoption. However, further research and statistical comparisons are needed to validate these estimations.

Summary: Reducing soil degradation and its impacts on the environment is a major challenge in the 21st century, especially due to the link between population growth and soil degradation. Beneficial microorganisms, particularly arbuscular mycorrhizal fungi (AMF), play a crucial role in soil amelioration. Glomalin produced by AMF contributes to mitigating soil degradation. Understanding the role of glomalin and AMF in the restoration of degraded soils can improve sustainable restoration efforts.
