Abstract

Grasslands play a major role in maintaining the stability and resiliency of ecosystems. This project explored the role that grazing system management could play to influence carbon sequestration and methane oxidation.

Key Question

Can grazing management be used to manipulate soil carbon sequestration (SOC) and cow enteric methane emissions to reduce net greenhouse gas emissions?

Findings

Over three years, the particular stocking system used did not affect SOC sequestration in cool season grass pastures that were established for at least 22 years. In contrast, cow enteric methane emissions could be reduced by limiting daily forage allowance to less than three percent of bodyweight. But, to utilize this strategy without adversely affecting calf production, cattle must be bred and/or selected for improved feed efficiency.
