Implementing continue straw returning practices and optimizing nitrogen application can mitigate nitrogen losses and enhance nitrogen use efficiency (NUE) in dryland. N-labeled technique offers a robust approach for tracking fertilizer nitrogen fate and assessing nitrogen use efficiency. Based on the continue (>6 yr) experiment, we conducted a two-year experiment (2020 and 2021) to evaluate the effects of straw returning and nitrogen management under plastic film mulching on N recovery rates, NO emissions and maize yield with three treatments: no straw returning with 225 kg N·ha under plastic film mulching (RP-N), straw returning with 225 kg N·ha under plastic film mulching (RPS-N), and straw returning with 20% nitrogen reduction (180 kg N·ha) under plastic film mulching (RPS-N).

Plastic film mulching is commonly used in the Loess Plateau region. Incorporating slow-release fertilizers as a replacement for urea within this practice can reduce nitrogen losses and enhance crop productivity.

Therefore, we conducted a comprehensive meta-analysis of 2103 paired observations, examining GGE, soil organic carbon (SOC) and plant carbon in plant mixtures and monocultures. Our findings indicate that plant mixtures decrease soil NO emissions by 21.

Deep eutectic solvents (DESs) are considered as designable solvents, which has attracted intensive attention for CO capture. Here, a series of binary DESs are synthesized through one-step mixing with the starting materials of protic ionic liquid (PIL) and amine.

Especially, aromatic VOCs including benzene, toluene, ethylbenzene, and xylene (BTEX) are important indoor air pollutants. Developing highly efficient porous adsorbents with broad applicability remains a major challenge.
View Article and Find Full Text PDFLow-viscous homologue-paired liquids (HPLs) are designed and employed as special non-ionic deep eutectic solvents for selective separation of SO from CO and N. The HPLs are found to have excellent inherent properties (, low cost, volatility and viscosity), high absorption capacity, fast absorption rate, and moderate Lewis acid-base interaction with SO. Regeneration experiments are done to show their excellent recyclability, and industrial desulfurization is exemplified in a small column with suitable parameters to show their potential as SO absorbents.
