Summary: The study found that adding biochar could increase soil pH and saturated moisture, while aged biochar had more oxygen-containing functional groups and exhibited higher hydrophilicity and polarity. The sorption mechanism of unamended soil with SPY primarily resulted from the weak hydrophobic distribution. Both fresh and aged biochar-amended soil increased SPY sorption due to improved H-bonding interaction between SPY and biochar surface functional groups.

Summary: This study investigated the effects and mechanisms of microplastics (MPs) on the sorption-desorption, bioaccessibility, and bioavailability of cadmium (Cd) in paddy soil. The experiments showed that MPs significantly reduced Cd sorption in soil by covering the soil active sites and interrupting formation of CdCO3 and Cd3P2 precipitates. This led to an increase in Cd bioaccessibility and bioavailability in soil. The findings provide new insights into the impacts of MPs on the fate and risk of heavy metals in agricultural soil.

Summary: The study found that the application of glyphosate (2592 g a.i. ha(-1)) and the sequential application of glyphosate can result in higher levels of intoxication. However, the combination of B. subtilis BV02 with glyphosate (2592 g a.i. ha(-1)) can prevent losses in relative chlorophyll a and b values and the total chlorophyll index. Soybean yield is reduced when plants are subjected to a sequential application of glyphosate.

Summary: The widespread occurrence of herbicide-resistant weeds and more variable weather conditions across the United States has made weed control in many crops more challenging. Preemergence herbicides with soil residual activity have resurged as the foundation for early season weed control in many crops. Field experiments were conducted to evaluate the weed control efficacy of solo and premix preemergence herbicides in conventional tillage corn. The results showed that herbicides with two or more site of action (SOA) provided greater weed control than herbicides with a single SOA, indicating that at least two SOA herbicides applied preemergence result in better early season weed control. The efficacy of the herbicide treatments varied according to the weed community composition and environmental conditions.

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.
