Summary: Humic acid, derived from lignite, is a popular organic fertilizer resource that affects the carbon balance of agricultural ecosystems. Through experiments, it was found that the application of humic acid can increase crop yield and soil CO2 emission, with soil NO3--N, available phosphorus, and available potassium being the main factors affecting soil CO2 emission. Furthermore, the level of humic acid use is related to the carbon balance of the ecosystem, as higher levels of humic acid application can increase CO2 sink in the atmosphere.

Summary: Cryogenic vacuum extraction (CVE) is widely used in ecohydrological research for plant water stable isotope analysis. However, recent studies have found that CVE can introduce significant bias in stable isotope analyses, especially in deuterium values. This study conducted rehydration experiments on plant samples and found that the deuterium bias induced by CVE is linearly correlated to the xylem water content, and is influenced by plant organs/species and the isotopic signature of the spiking water.

Summary: We studied root water uptake responses of three revegetation species (Hippophae rhamnoides, Platycladus orientalis, and Robinia pseudoacacia) in the dry and rainy seasons. The results show that Hippophae rhamnoides and Robinia pseudoacacia mainly extract water from the middle soil layer, while Platycladus orientalis extracts water from the deep soil layer. These findings are helpful in selecting the optimal revegetation species for water use.

Summary: In this study, a 98 m soil core from the Loess Plateau of China was sampled and the relationship between pore water isotopic values and hydroclimate history was examined. The results showed that the δO-18 and δH-2 values between 14-50 m were anomalously low, corresponding well to the Little Ice Age period from 1420 to 1870. This identification was consistent with other standard proxies in the region and revealed the temporal dynamics of temperature anomalies. The study highlights the potential of stable isotopes of soil water for paleoclimate reconstruction in deep soils.

Summary: Accurate estimation of groundwater recharge is essential for assessing its spatial variation at different scales. In this study, field variation in groundwater recharge was evaluated using multiple tracers in the deep vadose zone on the Chinese Loess Plateau. The results showed no significant differences in recharge rates among the sites, and the recharge estimates by different tracers' methods did not differ significantly. However, the chloride mass balance method indicated higher variations in recharge rates compared to the peak depth method. Considering the contribution of immobile water, the peak depth method overestimated groundwater recharge. This study provides valuable insights for accurate estimation of groundwater recharge and its variation in the deep vadose zone.

Summary: This study investigates the impacts of water and heat stress on carbon uptake in China and explores the driving mechanisms of droughts using a machine learning model. The results show that droughts are mostly driven by atmospheric dryness, with precipitation, relative humidity, and temperature playing dominant roles. Water and heat stress have negative impacts on carbon assimilation, and drought occurrence is projected to increase significantly in the future. Improving ecosystem resilience to climate warming is crucial in mitigating the negative effects of droughts on carbon uptake.

Summary: With the rapid increase of urbanization, evapotranspiration (ET) in urban forests has become increasingly important in urban hydrology and climate. However, there is still a large uncertainty regarding the factors that regulate ET in urban areas. This study investigates the temporal variations of ET in an urban forest park in Beijing using the eddy-covariance technique. The results show that daily ET is close to zero during winter but reaches 3-6 mm day-1 in summer. Daily ET increases with vapor pressure deficit (VPD) and soil water content (SWC). Monthly ET increases linearly with normalized difference vegetation index and shows a strong correlation with surface conductance (gs), while exhibiting saturated responses to increasing monthly precipitation (PPT). Annual ET ranges from 326 to 566 mm, and soil water replenishment through PPT from the previous year is responsible for the generally higher monthly ET in spring relative to PPT. Biotic factors and PPT seasonality play essential roles in regulating ET at different scales.

Summary: As climate change is expected to increase the intensity and frequency of extreme weather events, it is crucial to assess their impact on cropping systems and explore adaptation options. Process-based crop models (PBCMs) have improved in simulating the impacts of major extreme weather events, but still struggle to reproduce low crop yields under wet conditions. This article provides an overview of the yield-loss mechanisms of excessive rainfall in cereals and the associated modelling approaches, aiming to guide improvements in PBCMs.

Summary: Sustainable rice farming practices are urgently needed to meet increasing food demand, cope with water scarcity, and mitigate climate change. Traditional farming methods that prioritize a single objective have proven to be insufficient, while simultaneously optimizing multiple competing objectives remains less explored. This study optimized farm management to increase rice yield, reduce irrigation water consumption, and tackle the dilemma of reducing GHG emissions. The results suggest that the optimized management can maintain or even increase crop yield, while reducing water demand and GHG emissions by more than 50%.
