Sustainable plant nutrition and soil carbon sequestration
(Nova Science Publishers, Inc., 2022) Brajesh K. Dwivedi; Ashutosh K. Srivastava; Vijai Krishna
During the last 200 years, increasing anthropogenic activities have substantially increased the level of atmospheric carbon. Because of their significance in the earth's carbon cycle, mechanisms regulating carbon fixation in soils have received a lot of attention in recent years. Two-thirds of the planet's terrestrial organic carbon deposits are stored in soils as terrestrial carbon pools. Soil organic carbon has a gradual turnover pattern in terrestrial ecosystems and thus there is a massive possibility to capture atmospheric CO2 in soil ecosystems. Depending upon soil management practices it can be served as a cause or sink for atmospheric CO2. Sustainable management systems and practices such as conservation agriculture, agroforestry, and application of biochar are emerging and promising tools for soil carbon sequestration. Increasing soil carbon storage in a system simultaneously improves soil health by increasing infiltration rate, soil biota and fertility, nutrient cycling, and decrease in soil erosion process, soil compaction, and carbon emissions. As a consequence, it is necessary to research the processes governing carbon flux in soils, which are poorly defined in diverse environments under anthropogenic interventions, thereby establishing soil as a potential sink for atmospheric CO2 and limiting climate change. Therefore, the present chapter aims to review the basic mechanism leading to carbon stabilization in soils and new practices and technological developments in agricultural and cropland sciences for carbon sequestration. © 2022 Nova Science Publishers, Inc..
