Summary: Livestock grazing in riparian areas has both positive and negative effects on vegetation. While reserving riparian areas can benefit native vegetation, livestock grazing can reduce exotic vegetation cover at the cost of native vegetation and ground condition. Quantitative monitoring and evaluation of cost-benefit trade-offs are essential for guiding reservation decisions.

Summary: This study examines the seasonal characteristics of vegetation greening in China and its association with soil moisture and temperature changes. Using high-resolution datasets, the study finds that 56.8% of land area in China experienced a greening trend while 6.6% experienced a browning trend. The findings suggest that soil heat and water conditions play a significant role in translating global warming signals.

Summary: This study investigated the characteristics of a grassland vegetation community at different grazing gradients and growing seasons and its impact on soil moisture (SM) inversion using remote sensing data. The calibrated water cloud model (WCM) achieved accurate prediction results of SM inversion, with NDWI1 producing higher estimation accuracy than NDWI2. The developed WCM has the potential to enhance SM prediction capacity in typical grasslands.

Summary: Accurate global soil moisture data are crucial for modeling land surface hydrological cycles and monitoring climate change. In this study, a new soil moisture retrieval method based on robust regression is proposed to address the issue of noise in observations. The results show that the proposed method has better performance compared to linear regression methods and can accurately estimate soil moisture.

Summary: The study in the ecologically fragile Mongolian Plateau reveals a significant decrease in soil moisture with groundwater as the dominant influence. Precipitation and potential evapotranspiration are the main control factors for soil moisture spatiotemporal variability, with interactions among factors playing a crucial role.Meteorological forcing is not the sole dominator of soil moisture spatiotemporal variability, and different factors have varying influences across ecological zones.

Summary: The NASA SMAP satellite mission aims to produce enhanced resolution surface soil moisture products by combining L-band active and passive microwave measurements. This study tested the covariation between active and passive signals using numerical simulations and global satellite observations, focusing on the role of vegetation canopy in modulating the active-passive relationship. The results show that a linear relationship between backscatter and emissivity can be established under various vegetation conditions, with decreasing coupling between active and passive signals with increasing vegetation water content.

Summary: This study investigated the changes in vegetation and soil properties over time in natural and artificial vegetation types. It found that natural vegetation improved both plant community and soil properties, while artificial vegetation only improved soil nutrients but caused soil desiccation which is difficult to recover.

Summary: The study investigated the impact of vegetation restoration on soil moisture dynamics on the Loess Plateau of China using earth system reanalysis data and the Community Land Model (CLM). Results showed that while the surface layer soil moisture responded positively to vegetation restoration, the subsurface and deeper soil layers had negative responses. Overall, there was a decreasing trend in soil moisture during the simulation period, with significant differences observed spatially and seasonally.

Summary: The research demonstrates that utilizing soil moisture and vegetation optical depth data from NASA's SMAP mission can improve the prediction accuracy of leaf area index, with a more significant impact on grasslands. Soil moisture is more important in arid regions, while vegetation optical depth has a lesser influence.

Summary: This study evaluated the impacts of soil moisture and drought on vegetation phenology in the Mongolian Plateau. The results showed a negative trend in soil moisture and an increase in drought, which had significant effects on vegetation phenology. The study also found strong seasonal variations in the influence of soil moisture on vegetation, which decreased with soil depth.

Summary: The survey found that most organic corn growers in the region had small farms with diversified livestock operations, and emphasized soil fertility and health management. Organic corn growers heavily relied on moldboard plow tillage, and all producers had positive net returns to labor and management in 2017. These findings have implications for assessing the sustainability of organic farming systems and designing research programs to meet the needs of the diverse organic farming population in the region.

Summary: Kernza(R) intermediate wheatgrass is a novel perennial cool-season grass that can be used as a dual-purpose grain and forage crop through intercropping with medium red clover or corn-soybean-spelt rotation. The sustainability of this cropping system is highly dependent on how the hay or straw co-product is used and the extent to which external inputs can be substituted with locally available renewable resources.
