New research on carbon capture in grasslands

By Scout Nelson

A research project in North Dakota is examining underground carbon storage, which could have positive implications for ranchers.

Rebecca Phillips, who holds a doctorate in environmental sciences and engineering-biochemistry, is spearheading this effort at a ranch near McKenzie in Burleigh County. Her focus is to quantify the carbon that perennial grasses can secure in their root systems over time.

During a recent demonstration, Phillips explained that they aim to capture a comprehensive figure representing the total annual influx of carbon into that ecosystem.

This research could pave the way for ranchers to benefit financially from carbon storage credits, especially as interest from companies in carbon offsets grows.

Heaton noted the lack of similar studies on grasslands, which are typically overshadowed by research focused on croplands. Unlike crops that store carbon mainly above ground, grasslands deposit carbon primarily in their roots, offering a different dynamic in carbon sequestration.

Phillips views cattle as beneficial to natural carbon storage processes, countering the narrative that livestock significantly contribute to greenhouse gas emissions. She said it can fundamentally alter the discourse surrounding beef and cattle, highlighting the role of livestock in enhancing soil carbon levels.

Preliminary findings from the ongoing two-year study reveal that grazed pastures accrue more carbon than ungrazed ones.

The research is thorough, considering various factors that influence carbon dynamics, including the carbon contribution and removal by cattle. Phillips has employed advanced tools like soil sample extractors, sunlight, carbon dioxide, and water vapor monitors, as well as sophisticated rain gauges to gather comprehensive data.

Backed by entities including the North Dakota Industrial Commission, Hess Corporation, and various outdoor agencies, the project aims to develop models that can be applied to other ranches.

As the study progresses, Phillips is optimistic about expanding the research to include methane monitoring, enhancing the potential benefits of this innovative approach to ranch management and environmental conservation.
