Dinitrogen oxide production by a mixed culture of nitrifying bacteria during ammonia shock loading and aeration failure [PDF]

, 2002
A number of experiments was conducted in order to establish if N2O in the exhaust gas from an aerobic consortium of nitrifiers could be used as an indicator for monitoring the nitrification process.

Short-term effects of nitrapyrin, rice straw and its biochar application on N transformation in soils of humid subtropical China

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2018
The features of N transformations in humid subtropical soils vary greatly due to the wide variations of soil properties, particularly soil pH. Purpose: To understand whether the effects of countermeasures regulating N transformation varied with the ...

Simultaneous heterotrophic nitrification and aerobic denitrification potential of Paenibacillus sp. strain GLM-08 isolated from lignite mine waste and its role ammonia removal from mine waste water

Water Science and Technology, 2022
Paenibacillus sp. strain GLM-08 was isolated from a lignite mine waste site in the Barmer basin, Rajasthan, India. The strain is efficient in heterotrophic nitrification and aerobic denitrification. This bacterium could remove approximately more than 95%

Comparison of nitrification inhibitors to restrict nitrate leaching in a maize crop irrigated under mediterranean conditions

, 2010
The aim of this paper was to compare dicyandiamide (DCD) and 3,4 dimethylpyrazole phosphate (DMPP) as inhibitors of ammonium oxidation and nitrate leaching after applying fertilizer to a maize (Zea mays L.) crop grown under Mediterranean conditions.

Effects of Nitrification Inhibitors on Soil Nitrification and Ammonia Volatilization in Three Soils with Different pH

Agronomy, 2021
The application of nitrification inhibitors (NIs) is considered to be an efficient way to delay nitrification, but the effect of NIs combinations on soil nitrification and ammonia (NH3) volatilization are not clear in soils with different pH values.

Contrasting Responses of N₂O Mitigation to Different Nitrification Inhibitors in Tea Plantation Soils

Horticulturae
Tea plantations are a hot-spot source of nitrous oxide (N2O) emissions in the agricultural system. Using nitrification inhibitors (NIs) is a promising way to mitigate agricultural N2O emissions and has been widely tested in many croplands.

Dissipation of nitrapyrin (nitrification inhibitor) in subtropical soils

, 2019
Nitrapyrin (2-chloro-6-(trichloromethyl)pyridine) is a specific nitrification inhibitor, applied in soils for reducing the nitrification process of nitrogenous fertilizers.

Comparison of Nitrification Rates in Blueberry and Forest Soils [PDF]

Journal of the American Society for Horticultural Science, 2002
Highbush blueberries (Vaccinium corymbosum L.) are long lived perennial plants that are grown on acidic soils. The goal of this study was to determine how blueberry cultivation might influence the nitrification capacity of acidic soils by comparing the nitrification potential of blueberry soils to adjacent noncultivated forest soils.
