The soil organic carbon sequestration of environmental sciences essay
Soil organic matter is not only a globally important carbon sink, but also regulates key soil functions and is a central component of healthy and productive soils. Oldfield et al. 2019. Increasing soil organic carbon SOC stocks in agricultural soils is therefore a promising strategy for both climate change mitigation and for the process of C sequestration involves fixation, transfer of fixed C to plant biomass and soils, and stabilization of organic C in the soil where it is present. is stored as SOC after interactions with soil microbes, minerals and aggregates. Terrestrial C sequestration, applying improved management methods, see. A soil organic carbon debt Pg was estimated at the global m soil, which has increased over the past two centuries due to the increasing use of agricultural and pasture land. This debt. To improve soil carbon sequestration capacity, the full process of the soil carbon cycle must be understood and quantified. It is essential to evaluate whether water erosion acts as a net source or sink of atmospheric CO2 at the basin scale, which encompasses the entire hydrological process. This study introduced an approach where carbon sequestration can occur through biological, physical or chemical processes. It can be natural or artificially man-made. The main purpose of carbon sequestration is to remove carbon from the atmosphere and store carbon in the soil. Fig. 23.2. Removing carbon from the air: The biosphere has the ability to increase carbon. Overall, the biome of the boreal forest, of the land surface and of the carbon C stock sequestered in the soil, the quality and decomposition rate of above-ground plant litter have been proposed as the fundamental determinants of long-term accumulation of organic matter in the bottom 3-6. However, much of the climate change and shifts in weather patterns have significantly affected food production systems, manifested in the form of crop damage, reduced yields and market instability. Water- and chemical-intensive agricultural practices have made the sector a major contributor to carbon emissions, which impact the global climate and nutrient cycle. The storage of organic carbon in soil is closely linked to global climate change and soil quality. Secondary sequence of agricultural abandonment under the Grain for Green Project GGP program generally promotes SOC sequestration in the karst region of Southwest China. This study investigated the control mechanism of. This article reviews existing knowledge on the role of the soil microbial community on the fate of soil carbon in response to agronomic measures. Our hypothesis is that optimizing soil and nutrient management for carbon sequestration while stimulating co-benefits for agriculture and the environment will primarily require insights into the role of large-scale carbon emissions from soil, one of the planet's most important carbon sinks, in the atmosphere. harmful effects on global climate change, soil quality and crops, 2.
