Carbon Footprint of Mediterranean Pasture-Based Native Beef: Effects of Agronomic Practices and Pasture Management under Different Climate Change Scenarios

Animals, 2020
A better understanding of soil organic carbon (SOC) dynamics is needed when assessing the carbon footprint (CFP) of livestock products and the effectiveness of possible agriculture mitigation strategies.

Direct biological fixation provides a freshwater sink for N2O

Nature Communications, 2023
Nitrous oxide (N2O) is a potent climate gas, with its strong warming potential and ozone-depleting properties both focusing research on N2O sources. Although a sink for N2O through biological fixation has been observed in the Pacific, the regulation of ...

Tracing N2O formation in full-scale wastewater treatment with natural abundance isotopes indicates control by organic substrate and process settings

Water Research X, 2022
Nitrous oxide (N2O) dominates greenhouse gas emissions in wastewater treatment plants (WWTPs). Formation of N2O occurs during biological nitrogen removal, involves multiple microbial pathways, and is typically very dynamic.

Nitrous Oxide Consumption in Oxygenated and Anoxic Estuarine Waters

Geophysical Research Letters, 2022
Estuaries emit a large but highly uncertain amount of Nitrous oxide (N2O) into the atmosphere. To better understand N2O cycling processes in estuaries, we provide the first direct observations of N2O consumption in the seasonally anoxic Chesapeake Bay ...

Mineralization dynamics of different commercial organic fertilizers from agro-industry organic waste recycling: an incubation experiment

Plant, Soil and Environment, 2014
The mineralization process of different commercial organic fertilizers was investigated in controlled laboratory conditions. The soil was mixed with the following organic fertilizers: Emos CAP®, Organ CAP®, Sic Stal® and urea (as a control) at the rate ...

Combination of nitrous oxide and the modified inflation‐deflation method for identifying the intersegmental plane in segmentectomy: A randomized controlled trial

Thoracic Cancer, 2021
Background During thoracoscopic segmentectomy, accurately and rapidly identifying the intersegmental plane (ISP) is of great importance. This study aimed to investigate the effect and safety of a nitrous oxide (N2O)/oxygen (O2) inspired mixture on the ...

Nitrogen addition turns a temperate peatland from a near-zero source into a strong sink of nitrous oxide

Plant, Soil and Environment, 2022
Peatlands, as important global nitrogen (N) pools, are potential sources of nitrous oxide (N2O) emissions. We measured N2O flux dynamics in Hani peatland in a growing season with simulating warming and N addition for 12 years in the Changbai Mountains ...

Proper interpretation of dissolved nitrous oxide isotopes, production pathways, and emissions requires a modelling approach. [PDF]

PLoS ONE, 2014
Stable isotopes ([Formula: see text]15N and [Formula: see text]18O) of the greenhouse gas N2O provide information about the sources and processes leading to N2O production and emission from aquatic ecosystems to the atmosphere.
