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.

Response of Nitrification and Crop Yield to the Presence of NBPT and DCD in a Wheat-Corn Double Cropping System

Agronomy, Journal Year: 2024, Volume and Issue: 14(2), P. 285 - 285

The excessive application of nitrogen fertilizer aggravated the loss in farmland and exerted detrimental effects on soil water environment. Examining N-(n-Butyl)thiophosphoric triamide (NBPT) nitrification inhibitor dicyandiamide (DCD) crop yield wheat-corn double cropping systems would provide valuable insights for improving efficiency ensuring a rational inhibitors. A field experiment lasting one half years was performed winter wheat–summer maize agroecosystem North China. four treatments that were applied included (I) conventional fertilization without inhibitors (CK), (II) with 0.26 g/m2 NBPT (NBPT), (III) 1.00 DCD (DCD), (IV) (NBPT + DCD). results demonstrated combined use better reducing NO3−-N leaching. Nitrification could be inhibited up to 95 days by combining DCD, while 21 DCD. Ammonia-oxidizing archaea (AOA) (R2 = 0.07159, p < 0.01) along ammonia-oxidizing bacteria (AOB) 0.09359, 0.01), rather than complete ammonia oxidizer (comammox), significantly positively correlated content, which indicated ammoxidation process mainly regulated AOA AOB, instead comammox
