Abstract Biochar-based sulfidized nano-sized zero-valent iron (SNZVI/BC) can effectively immobilize cadmium (Cd) in contaminated paddy soils. However, the synergistic effects between biochar and SNZVI on Cd immobilization, as well underlying mechanisms remain unclear. Herein, a soil microcosm incubation experiment was performed to investigate immobilization performance of SNZVI/BC towards soil. Results indicated that addition at dosage 3% significantly lessened concentration available from 14.9 (without addition) 9.9 mg kg −1 with an efficiency 33.3%, indicating effect. The sequential extraction results proportion residual increased 8.1 10.3%, manifesting transformation unstable fractions steadier specie after application SNZVI/BC. Also, pH, organic matter, dissolved carbon, which altered bacterial community soil, enriching relative abundances functional microbes (e.g., Bacillus , Clostridium Desulfosporosinus ). These microorganisms further facilitated generation ammonium, nitrate, ferrous enhancing nutrients’ availability. direct interaction 2+ physicochemical properties, responded played important roles Overall, biochar-based is promising candidate for effective improvement availability Graphical

Agrochemical residues and nitrous oxide (N2O) emissions have caused considerable threats to agricultural soil ecology. Nanoscale zerovalent iron (nZVI) nitrification inhibitors might be complementary each other diminish agrochemical N2O enhance bacterial community diversities. Compared the control, nZVI application declined paclobutrazol by 5.9% but also decreased co-occurrence network node. Combined Dicyandiamide applications significantly emission rates promoted Shannon diversity of community. The increased pH, ammonium nitrogen, Actinobacteriota could promote dissipation. generated double-edged sword effects positively decreasing negatively influencing multifunctionalities. in diminishing promoting diversities simultaneously.

The interaction of herbicides in the nitrogen cycle and their consequences on soil health agricultural production are essential topics agronomic research. In this systematic review article, we have synthesized recent studies subject. results revealed that indiscriminate use can negative effects vital processes cycle, such as reduced enzymatic activity microbial respiration. Moreover, alter composition, affecting cycling-related activities. Symbiotic fixation is also impaired, resulting a reduction population nitrogen-fixing bacteria decrease availability nutrient soil. These compromise fertility release to plants. Therefore, sustainable practices must be adopted, considering cycling efficiency preservation natural resources. This understanding crucial for guiding appropriate management strategies aimed at minimizing ensuring productivity.
