Soil carbon sequestration by root exudates
Did you know?
WebThe most significant pathway for carbon to enter the soil is through the root-mycorrhizal fungal network, which facilitates carbon sequestration and storage through root and hyphae exudates, turnover, and formation and stabilization of soil aggregates that protect organic matter from decomposition (Frey et al. 2024, Jones et al. 2009, Schmidt ...
WebRoot exudates can help to sequester carbon in forests. Forest soils sequester more soil carbon compared with cropland soils [. 4. ]. The SOC content in forests is close to 702 Gt for soil layers up to 100 cm, which is further divided into topsoils, 0–30 cm (342.6) and subsoils, 30–100 cm (359.5) [. WebAny carbon capture scheme must include corrections for the CO 2 emission during the sequestration process itself, such as fuel burned in growing, harvesting, transporting, drying, and compacting biomass, as well as manufacturing the polyethylene landfill liner, etc. Moreover, a small credit must be given for carbon in soil and plant roots.
WebNov 13, 2024 · For nearly 2 decades, researchers in the soil science community have studied and estimated the potential of sequestering carbon in soil organic matter (2, 3).The premise is inherently rational: nearly 10,000 years of cultivated agriculture has reduced global soil carbon by 116 Gt (), an amount equivalent to more than a decade of the present rates of … WebThird, we will take advantage of pre-existing differences in the 13C of soil organic matter in ambient and elevated CO2 soils to examine the total flux of C from roots and mycorrhizal fungi to soil. Roots will grow into in-growth cores filled with soil from one of the two CO2 treatments in a reciprocal transplant design (i.e. ambient CO2 roots ...
