  • 2018 - Fellow of the Soil Science Society of America (SSSA)

Overview

What is she best known for?

The fields of study she is best known for:

  • Ecology
  • Agriculture
  • Carbon dioxide

Claudia Wagner-Riddle mostly deals with Nitrous oxide, Greenhouse gas, Agronomy, Soil water and Fertilizer. Her study in Nitrous oxide is interdisciplinary in nature, drawing from both Environmental chemistry, Denitrification, Trace gas and Environmental engineering. Claudia Wagner-Riddle interconnects Eucalyptus, Methane, Land use, land-use change and forestry and Manure in the investigation of issues within Greenhouse gas.

Her Agronomy research includes themes of Biomass and Agriculture. Her work carried out in the field of Soil water brings together such families of science as Atmospheric sciences, Nitrogen cycle, Precipitation and Temporal scales. Her work is dedicated to discovering how Fertilizer, Nitrate are connected with Nitrogen dioxide and Animal science and other disciplines.

Her most cited work include:

  • Intensive measurement of nitrous oxide emissions from a corn–soybean–wheat rotation under two contrasting management systems over 5 years (209 citations)
  • Estimation of N2O emissions from agricultural soils in Canada. I. Development of a country-specific methodology (200 citations)
  • Estimates of nitrous oxide emissions from agricultural fields over 28 months (193 citations)

What are the main themes of her work throughout her whole career to date?

Claudia Wagner-Riddle spends much of her time researching Agronomy, Greenhouse gas, Manure, Nitrous oxide and Methane. Her studies in Agronomy integrate themes in fields like Soil water and Leaching. Her work deals with themes such as Cover crop, Waste management, Agriculture and Environmental protection, which intersect with Greenhouse gas.

The various areas that she examines in her Manure study include Slurry and Animal science. Her biological study deals with issues like Atmospheric sciences, which deal with fields such as Wind speed and Climate change. Her Methane research includes elements of Biogas and Environmental engineering.

She most often published in these fields:

  • Agronomy (35.29%)
  • Greenhouse gas (30.48%)
  • Manure (30.48%)

What were the highlights of her more recent work (between 2018-2021)?

  • Greenhouse gas (30.48%)
  • Nitrous oxide (29.41%)
  • Agronomy (35.29%)

In recent papers she was focusing on the following fields of study:

Her main research concerns Greenhouse gas, Nitrous oxide, Agronomy, Fertilizer and Manure. Her biological study spans a wide range of topics, including Cover crop, Environmental engineering, Methane and Environmental protection. Her Nitrous oxide research is multidisciplinary, incorporating perspectives in Nitrogen fertilizer, Legume, Climate change and Atmospheric sciences.

While the research belongs to areas of Agronomy, she spends her time largely on the problem of Soil management, intersecting her research to questions surrounding Contamination and Groundwater. Her Fertilizer research incorporates themes from Soil water, Leaching, Nitrification, Crop yield and Nitrate. Her study looks at the relationship between Manure and fields such as Animal science, as well as how they intersect with chemical problems.

Between 2018 and 2021, her most popular works were:

  • Modifying fertilizer rate and application method reduces environmental nitrogen losses and increases corn yield in Ontario. (9 citations)
  • Short-term response of soil N-cycling genes and transcripts to fertilization with nitrification and urease inhibitors, and relationship with field-scale N2O emissions (9 citations)
  • Quantifying the relationships between soil fraction mass, fraction carbon, and total soil carbon to assess mechanisms of physical protection (9 citations)

In her most recent research, the most cited papers focused on:

  • Ecology
  • Agriculture
  • Carbon dioxide

Her primary scientific interests are in Agronomy, Nitrous oxide, Soil water, Fertilizer and Greenhouse gas. Her research in Nitrous oxide intersects with topics in Nitrogen fertilizer, Atmospheric sciences and Sowing. Her Atmospheric sciences study incorporates themes from Agriculture and Spring.

Her Soil water study combines topics from a wide range of disciplines, such as Animal science and Drainage. In her study, Tile drainage, Manure management, Silage and Manure is inextricably linked to Leaching, which falls within the broad field of Fertilizer. When carried out as part of a general Greenhouse gas research project, her work on Enteric fermentation and Carbon footprint is frequently linked to work in Productivity, Life-cycle assessment and Profitability index, therefore connecting diverse disciplines of study.
