Sensing Technologies to Uncover the Effects of Crop Root Systems on Greenhouse Gas Emissions

Abstract

Altering the rhizosphere of crops to reduce greenhouse gas (GHG) emissions and enhance carbon sequestration can be an effective strategy for combating global warming. However, research on the relationship between crop root traits and GHG emissions is limited and lacks comprehensive understanding. This review outlines the general mechanisms of GHG production and emission, summarizes the sensing technologies for the rhizosphere and GHGs along with their challenges, and discusses the potential of altering crop root traits to reduce GHG emissions based on the latest research to facilitate advancements in this field. Additionally, the trade-offs between GHG emission reduction and carbon sequestration are shown and the practical measures for global warming prevention are discussed.
