Soil carbon storage is a vital ecosystem service, resulting from interactions of ecological processes. Human activities affecting these processes can lead to carbon loss or improved storage.
Effective land-based solutions to climate change mitigation require actions that maximize soil carbon storage without generating surplus nitrogen.
Soil-based carbon sequestration is a way to remove CO2 from the air and store it somewhere it can’t easily escape: in soils, which store carbon in the form of broken-down plant matter.
Physical and chemical stabilisation mechanisms are now known to play a critical role in controlling carbon (C) storage in mineral soils, leading to suggestions that climate warming-induced C...
1. Productive soil. Only about 42 per cent of the carbon in a forest is contained in the plant matter above the ground. The rest is made up of the roots, soil organisms and partially decomposed matter in the soil. 2. Setting down roots. Plant roots grow into deeper layers of soil.
Soil is the largest carbon (C) reservoir in terrestrial ecosystems and plays a crucial role in regulating the global C cycle and climate change. Increasing nitrogen (N) deposition has been widely considered as a critical factor affecting soil organic carbon (SOC) storage, but its effect on SOC components with different stability remains unclear. Here, we analyzed extensive empirical data from ...
Soil organic matter comprising of approximately 58% of soil organic carbon (SOC) is the basis of many soil functions and ecosystem services, including provision of food and fiber, habitats for biodiversity, climate regulation, water filtration and purification, and human heritage.
Soil physical fractioning is an important tool for the understanding of soil carbon storage in the fractions > 53 µm (related to particulate organic carbon), and < 53 µm (related to mineral-associated carbon). Fig. 4 presents the total carbon percentage held in each soil fraction in the four farms.
The objective of this review is to identify measurable biotic or abiotic properties that control soil organic carbon (SOC) storage at different spatial scales and could serve as indicators for an efficient quantification of SOC.
Some carbon is stored in plants—especially woody plants and grasslands—as a result of the biological process of photosynthesis. This process removes CO2 from the atmosphere and transforms it into living plant tissues. Plants also move carbon into soil, producing something called soil organic carbon. Soil contains massive amounts of organic ...
