Article Abstract
Decarboxylative alkylation of carboxylic acids with easily oxidizable functional groups such as phenol and indole functionalities was achieved using a catalytic amount of basic iron(III) acetate, Fe(OAc)(OH), in the presence of benzimidazole under 427 nm LED irradiation. Kinetic analyses of this catalytic reaction revealed that the reaction rate is first-order in alkenes and is linearly correlated with the light intensity; the faster reaction rate for the benzimidazole-ligated species was consistent with the increased absorbance in the visible light region. Wide functional group tolerance for the easily oxidizable groups is ascribed to the weak oxidation ability of the in situ-generated oxo-bridged iron clusters compared with other iron(III) species.

Peatlands are one of the most important terrestrial carbon storage reservoirs. The response of soil labile organic carbon fractions to environmental changes is a pivotal indicator for assessing the stability of soil organic carbon pools. Soil enzymes act as primary participants in the biogeochemical processes of peatlands, significantly influence the material cycling and energy flow.

To investigate the impact of different tillage practices on the organic carbon pool and the stoichiometry characteristics of extracellular enzymes in black soil farmland， a continuous 6-year field experiment was conducted. This study evaluated the effects of conventional tillage （CT）， no-till with straw mulching （NTS）， subsoiling tillage with straw strip mulching （STS）， and moldboard plowing with straw returning （MPS） on active organic carbon components， organic carbon pool， enzyme activity， and enzyme stoichiometric characteristics in the 0-40 cm soil layer. The results showed that compared with those in the CT treatment， the NTS， STS， and MPS treatments significantly increased the contents of easily oxidizable organic carbon （EOC）， particulate organic carbon （POC）， soil organic carbon （SOC）， carbon pool index （CPI）， and carbon pool management index （CPMI） in the 0-40 cm soil layer， with increases of 7.

Litter plays a crucial role in the formation and turnover of soil organic carbon (SOC). However, its impact on SOC in black soils with varying degradation levels remains unclear. With the typical black soils in northeastern China with different simulated degradation levels (slight, moderate, and severe), we comparatively analyzed the changes in total organic carbon (TOC), easily oxidizable organic carbon (EOC), particulate organic carbon (POC), dissolved organic carbon (DOC), and microbial biomass carbon (MBC) under silver poplar litter addition (LP) and maize straw addition (MS) versus a treatment without litter addition (CK) at 45 days (early stage), 90 days (mid stage), and 135 days (late stage) after litter addition in a field in-situ experiment.

It is crucial to lessen secondary pollution of plastic film mulching (PFM) in drylands, where high and stable yielding of crops are highly dependent on PFM. To explore the solution, field investigations were conducted in dryland maize using the plastic films with four different thicknesses (0.015, 0.

Reducing chemical fertilizer use while enhancing soil organic carbon (SOC) stability, through straw return and biochar amendment presents an integrated strategy for climate change mitigation and sustainable agriculture. However, the effectiveness of their carbon (C) sequestration potential and organic C pool stability is influenced by varing environmental conditions. This study investigated the effects of straw and biochar on C sequestration potential and SOC pool stability in jasmine garden soil in Fuzhou, China.
