Overview

Tim J. Clough is affiliated with Lincoln University in New Zealand. The research primarily spans the fields of Environmental Science and Agricultural and Biological Sciences, with a strong focus on soil-related studies and sustainability.

The main subfields of study encompass Soil Science, Environmental Chemistry, Ecology, Environmental Engineering, and Civil and Structural Engineering. Key topics in their work include Soil Carbon and Nitrogen Dynamics, Soil and Water Nutrient Dynamics, Peatlands and Wetlands Ecology, Soil and Unsaturated Flow, Wastewater Treatment and Nitrogen Removal, Microbial Fuel Cells and Bioremediation, and Groundwater flow and contamination studies.

Selected recent publications illustrate the scope of Tim J. Clough's research:

Mitigation of nitrous oxide emissions in the context of nitrogen loss reduction from agroecosystems: managing hot spots and hot moments (2020), published in Current Opinion in Environmental Sustainability
Global Research Alliance N₂O chamber methodology guidelines: Design considerations (2020), published in Journal of Environmental Quality
