Soil Carbon

This edited book discusses how effective soil carbon management plans and policies will ultimately make agriculture more secure against climate change and soil degradation. It is focused on initiatives to enhance soil organic carbon (SOC) and sequestration by launching different schemes and programs. An approach based on practical aspects of managing SOC in agriculture is provided with clear and concise descriptions. It has more attention to successfully implement plans and policies to meet the required level of SOC restoration.

The book provides an overview relevant to various biological mechanisms that regulate carbon exchanges between the major components and their response to climate change. Climate change has a significant impact on people's lives, energy demand, food security, etc. The soil microbial ecology is vital for assessing terrestrial and aquatic carbon cycles and climate feedback. However, the primary concern is the complexity of the soil microbial community and its severely affected functions due to the climate and other global changes. Global warming comprises an assessment of the dynamic interactions and feedback between microbes, plants, and their physical environment due to climate change.

Soil is a complex system of inorganic and organic materials, living organisms, water, and air. It is home to more than one trillion species of microorganisms. Soil also plays an important role in the global carbon cycle. Because plants absorb carbon from the atmosphere, convert it to plant tissue, and return it to the soil as plant residue, soils globally act as the world’s largest sink of active carbon. Soil has role to play in food production and safety. Soil contamination undermined by modern agricultural practices that deplete soil carbon stocks. Anthropogenic greenhouse gas emissions have been raising recorded temperatures since the Industrial Revolution. Greenhouse gas emissions from agriculture, forestry, and fisheries have almost doubled in the last 50 years and will increase by 30% by 2050 given the current trend. The primacy of arresting climate change is nowhere more evident than the adoption of 195 countries of the first legally binding global climate deal at the Paris Climate Conference in 2015. With atmospheric carbon dioxide (CO2) reaching 400 parts per million in 2016, soils can be an ally in bringing the CO2 level down to a sustainable level if protected for regeneration. Soil protection and regeneration is a technique that involves the conservative rehabilitation of soil ecosystem and farmland.
