Abstract
Purpose The oxidation of ammonium (NH4+) to nitrate(NO3−) in the soil is an important biogeochemical process,which has major environmental implications as it can contribute to NO3− leaching and nitrous oxide (N2O) emissions.Nitrification inhibitors have been used to slow down this process to reduce NO3−leaching and N2O emissions from agricultural land.The objective of this study was to determine the effectiveness of a liquid formulation of 3,4-Dimethylpyrazole phosphate (DMPP) compared with a dicyandiamide (DCD) solution in inhibiting the growth of ammonium-oxidizing bacteria (AOB) and ammonium oxidizing archaea (AOA) and slowing down the rate of NH4+ oxidation in soil.
Materials and methods An incubation study was conducted to determine the effect of liquid DMPP and a DCD solution on AOB and AOA population growth and on the rate of NH4+ oxidation following the application of an ammonium source in the form of animal urine at the equivalent rate of 1,000 kg N ha−1 in six grazed grassland soils.
Results and discussion The results showed that the growth of the AOB population,as measured by the functional amoA gene copy numbers,was effectively inhibited by both DMPP and DCD.This inhibition by both inhibitors significantly decreased the ammonium oxidation rate constants in all six soils.The half-lives of ammonium in the soils were significantly (

氧化铵 (NH4 +)，nitrate(NO3−) 在土壤中的目的，是重要的生物地球化学过程，它可以有助于 NO3− 浸和一氧化二氮 (N2O) 排放有着重大的环境影响。硝化抑制剂已被用来减缓这个过程，减少农业土地的 NO3−leaching 和一氧化二氮排放。这项研究的目的是氧化的要确定有效性的 3，4-二甲基吡唑磷 (DMPP) 的液剂抑制生长的氨氧化细菌 （AOB）、 铵氧化古 (AOA） 和 NH4 + 在土壤中速率减慢双氰胺 (DCD) 解决方案相比。
材料和方法来确定液体 DMPP 与 DCD 解决方案影响 AOB 与 AOA 人口增长和 NH4 + 铵源动物尿量为 1000 公斤 N ha−1 六放牧的草地土壤中的等效速度的形式申请后的氧化速率进行孵化研究。
结果和讨论结果表明 AOB 人口的增长功能 amoA 基因拷贝数，以衡量被有效地抑制由 DMPP 和 DCD。这两种抑制剂抑制大幅度减少所有六个土壤中的铵氧化速率常数。土壤中铵的半衰期，显著 (< 0.05） 由 31 增至 58 天尿治疗时已应用 DCD 或 DMPP 109–285 天。没有显著差异 NH4 + 氧化率之间有 DMPP 和 DCD 跨六土壤处理。这些结果表明 DMPP 和 DCD 都有可能被用来治疗放牧的结论草地土壤硝态氮淋失贡献和氧化亚氮排放量减少。
