Application

  • Biological and chemical nitrification inhibitors exhibited different effects on soil gross N nitrification rate and N(2)O production: a (15)N microcosm study.: This study examines the effects of biological and chemical nitrification inhibitors, including 2-Chloro-6-(trichloromethyl)pyridine, on soil nitrogen processes. The findings highlight the differential impacts on soil nitrogen dynamics and greenhouse gas emissions (Lan et al., 2023).
  • Nitrous oxide emissions from manured soils as a function of various nitrification inhibitor rates and soil moisture contents.: This paper explores the relationship between nitrification inhibitor application rates, including 2-Chloro-6-(trichloromethyl)pyridine, and soil moisture on nitrous oxide emissions, providing insights into optimizing inhibitor use for environmental benefits (Lin and Hernandez-Ramirez, 2020).
  • Nitrate losses in subsurface drainage from a corn-soybean rotation as affected by fall and spring application of nitrogen and nitrapyrin.: Investigating the seasonal application of nitrapyrin, a derivative of 2-Chloro-6-(trichloromethyl)pyridine, this study assesses its efficacy in reducing nitrate leaching and improving nitrogen use efficiency in agricultural systems (Randall and Vetsch, 2005).
  • Oxidation of Nitrapyrin to 6-Chloropicolinic Acid by the Ammonia-Oxidizing Bacterium Nitrosomonas europaea.: This foundational research elucidates the microbial degradation pathway of nitrapyrin, contributing to our understanding of its environmental fate and persistence (Vannelli and Hooper, 1992).

The nitrapyrin was easily adsorbed by soil, but most current studies have focused on comparing the effects of nitrapyrin application at different soil organic matter levels and in different soil types. The adsorption kinetics and isotherm adsorption of the nitrification

It has been shown that UV-A (lambda=320-400 nm) and UV-B (lambda=280-320 nm) inhibit photosynthesis, nitrogen fixation and nitrification. The purpose of this study was to determine the effects, if any, on denitrification in a microbial community inhabiting the intertidal. The

Nitrate production by Nitrosomonas europaea in inorganic liquid medium containing ammonium was limited by reduction in pH. In the presence of montmorillonite and vermiculite, expanding clays with high cation-exchange-capacity (CEC), nitrite yield was increased, ammonia oxidation continued at pH values
