3,4-dimethylpyrazole (DMPZ), when used as a nitrification inhibitor, exhibits volatility, poor thermal stability, high production costs, and limited functionality restricted to nitrogen fixation. To address these limitations introduce novel phosphorus-solubilizing soil-loosening abilities, herein, poly (acrylamide-co-acrylic acid)-encapsulated NI (P(AA-co-AM)-e-NI) is synthesized by incorporating linear P(AM-co-AA) macromolecular structures into systems. The P(AA-co-AM)-e-NI demonstrates an obvious phase transition from glassy state rubbery state, with glass temperature of ~150 °C. Only 5 wt% the weight loss occurs at 220 °C, meeting requirements high-tower melt granulation process (≥165 °C). DMPZ content in 1.067 wt%, representing 120% increase compared our previous products (0.484 wt%). can effectively reduce abundance ammonia-oxidizing bacteria prolong duration during which fertilizers exist form ammonium nitrogen. It also cooperatively enhance conversion insoluble phosphorus soluble presence (NH4+-N). In addition, upon adding soils, soil bulk density hardness decrease 9.2% 10.5%, respectively, permeability increases showing that it has good ability capacity regulate environment.
