What role do microorganisms play in carbon transformation and role of microorganisms in environmental sustainability in climate smart agriculture?
Microorganisms play crucial roles in carbon transformation within various ecosystems, including soil, water, and the atmosphere. Here are some key roles microorganisms play in carbon transformation:
In the context of climate-smart agriculture and environmental sustainability, microorganisms play essential roles in maintaining soil health, nutrient cycling, and greenhouse gas mitigation. Here are some ways microorganisms contribute to these goals:
- Biological Control of Pests and Diseases: Certain microorganisms, such as entomopathogenic fungi and bacteria, can act as biological control agents against pests and diseases in agricultural systems. Integrated pest management strategies that harness the natural antagonistic properties of microorganisms can reduce reliance on synthetic pesticides and promote environmental sustainability.
Microorganisms not only release carbon, but also play a crucial role in its storage and transformation within the soil. Some microbes, like certain bacteria, can fix atmospheric nitrogen, making it available for plants. Others form symbiotic relationships with plant roots, helping them absorb nutrients and water. Beneficial microorganisms found in the plant environment have numerous benefits to the plant ecosystem, including nutrient fixation and solubilization, stress management, phytohormone production, plant phenology, improved yield, and many other positive effects. 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. Microbes found in soil and aquatic environments contribute directly to the ongoing rise in greenhouse gas emissions by producing key greenhouse gases: carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Microbes in aquatic and terrestrial environments produce and consume the greenhouse gases CO2, CH4 and N2O. Microbes contribute significantly to addressing these challenges through nutrient cycling, bioremediation, waste management, renewable energy production, climate change mitigation, ecosystem health maintenance, and enhancing agriculture and food security. Methane consuming microorganisms are critical to maintaining a healthy climate on Earth. Bacteria use methane for metabolism as energy source. Methanotrophic bacteria is consume methane as their only source of energy and convert it to carbon dioxide during their digestive process.
