Microbial impact on climate-smart agricultural practices

Abstract

Microbes play a fundamental role in the subsistence of all ecosystem processes. As a result, soil microorganisms are integral parts of several biogeochemical cycles and agroecosystem resilience functions against organic matter degradation, soil nutrient deficiency, and reducing greenhouse gas (GHG) emissions. In recent years, studies have shown that agriculture and associated land-use change remains a major source of biogenic GHGs, such as carbon dioxide (CO2), methane, and nitrous oxide. In this study, we provided a systematic selection of novel experimental studies to highlight the impact of climate change consequences such as elevated CO2, temperature, and drought on microbial functions in different agroecosystems. The role of microbes in climate-smart agriculture management strategies to influence crop yield, soil carbon sequestration, GHG mitigation, and climate change adaptation was expounded.
