Summary: The characteristics of runoff and soil loss on slopes and their responses to soil conservation measures and soil properties have been studied using runoff and sediment data from runoff plots with two contrasting soils in northeastern China. The implemented soil conservation measures effectively control soil loss, but downslope ridge tillage and bare plots have higher soil loss rates. The black soil region in northeastern China, especially the Phaeozenm soil, should be given priority for implementing soil conservation measures.

Summary: This paper presents an in-depth review of the assessment of rainfall erosivity in Brazil over the past three decades. The most commonly used erosivity index in the country is EI30, and pluviographic rainfall data and regression equations are the main methods for obtaining erosivity values. Annual rainfall erosivity in Brazil ranges from 59 to 26,891 MJ mm ha(-1)h(-1) year(-1), with the lowest values found in the Northeast region and the highest in the North. Kriging is the most widespread technique for obtaining rainfall erosivity maps in Brazil. The Southeast region has the highest number of erosivity studies, while the North lacks erosivity information. Recent advancements include the use of synthetic series of rainfall and remote sensing products, as well as machine learning techniques for interpolation. Future research is expected to focus on these methodologies and the assessment of future patterns of rainfall erosivity in Brazil. This review provides updated findings on rainfall erosivity assessment in Brazil and contributes to soil and water management planning at a national scale.

Summary: No-till farming is widely used in grain production in Brazil, but it leads to soil degradation due to the lack of runoff control and low phytomass input. Surface runoff transports chemical elements impacting water quality. This study evaluated the influence of phytomass amount, chiseling, and terracing on nutrient loss in surface runoff and sediment. The findings showed that nutrient concentrations varied, but the dissolved fraction of surface runoff was the major contributor to nutrient loss during high-magnitude rainfall events. Increased phytomass and the presence of terraces affected nutrient losses.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.
