Undisturbed primary forests store large amounts of organic carbon (OC) in the soil, making them a valuable carbon sink for mitigating climate change [1,2].Nowadays, a growing number of primary forests are being converted to plantations, secondary forests, and other land uses due to climate change and human disturbance [3,4,5].It causes a …
Based on large-scale soil radiocarbon (∆ 14 C) measurements on the Tibetan Plateau, we found that plant carbon input was the major contributor to topsoil carbon destabilisation despite the significant associations of topsoil ∆ 14 C with climatic and mineral variables as well as SOM chemical composition. By contrast, mineral protection by ...
Root exudates can either promote or impede the formation of stable, mineral-associated soil organic carbon (MAOC). Yet, carbon stabilisation in MAOC is decoupled from changes in the total soil ...
To be able to grow, develop, and produce at their best, plants must have specific elements or compounds called plant essential nutrients. A plant that lacks an essential nutrient cannot complete its life cycle — the seed may not germinate; the plant may not be able to develop roots, stems, leaves, or flowers properly; or it may not be able to produce seeds …
As shown in Figure 31.3, carbon is a key part of plant biomolecules, followed by oxygen (45 percent) and hydrogen (6 percent), which are the next two most abundant elements in plants. Figure 31.3 Cellulose, the main structural component of the plant cell wall, makes up over thirty percent of plant matter.
Biochar is a nature-based green solution to lift soil carbon storage and mitigate carbon release. Here, we propose a novel concept of biochar carbon pump (BCP) that bridges microbial carbon pump (MCP) and mineral carbon pump (MnCP), facilitating effective carbon sequestration. The BCP functions to promote carbon storage by …

Making Minerals. Carbon mineralization is the process by which carbon dioxide becomes a solid mineral, such as a carbonate. It is a chemical reaction that happens when certain rocks are exposed to carbon dioxide. The biggest advantage of carbon mineralization is that the carbon cannot escape back to the atmosphere.
Mineral-associated soil carbon buildup is poorly explained by microbial necromass production (a common hypothesis). During litter decomposition, these processes are decoupled by priming effects ...
Australian clean technology developer, Mineral Carbonation International (MCi) is constructing a world-first mobile demonstration plant at our site. MCi uses an engineering process to transform captured carbon dioxide (CO 2 ) emissions into solid materials known as 'carbonates' that can be used to manufacture a range of building and ...
Plants are able to continuously acquire carbon from the air (in the form of carbon dioxide); however, as stationary organisms, nutrient acquisition can become a challenge if the soil becomes depleted of a particular nutrient. Most land plants address this challenge by continually growing roots throughout the soil as they mine for minerals and ...
Carbon (C) CO 2 45 per cent. ... In this chapter, a brief overview of the history of plant mineral nutrition is provided. Soil serves as the source of nutrient elements, and so the availability of ...
CO 2 generated from power plants or industrial sources can be captured, compressed, and stored in reactive geologic formations where CO 2 in the fluid form …
Mineral nutrients required for plants in concentration exceeding one part per million (ppm) or 1–150 g per kg of plant dry matter are called macronutrients (C, H, O, N, P, K, Ca, Mg, S), and those required in concentration below 1 ppm are micronutrients or 0.1–100 mg per kg of plant dry matter (Fe, Mn, Cu, Zn, Mo, B and Cl).
Soil organic carbon (SOC) is an integral component of terrestrial ecosystems and plays an important role in ecosystem resilience and productivity.
The critical roles of minerals in OM persistence and accumulation in soils were further introduced in the "soil mineral carbon ... it is imperative to systematically consider plant-microbe ...
Carbon, hydrogen, and oxygen are de-rived from the atmosphere and soil water. The remain-ing 13 essential elements (nitrogen, phosphorus, po-tassium, calcium, …
Enhanced mineral protection of plant carbon under acid addition stimulated the accumulation of MAOC. Our result showed that acid addition significantly increased the MAOC in 10–20 cm soil, which is inconsistent with our second hypothesis. The increased MAOC depends on the balance between stabilizing the newly transformed carbon from …
Particulate and mineral-associated soil organic carbon have different climate sensitivity and distributions in Europe, according to analyses of measurements of soil carbon fractions from 352 topsoils.
a Mineral-associated organic carbon (MOC; g C kg −1 soil) as a function of clay and silt content (CS; %) across sites. The maximum slope (fit as the 95th quantile) for each soil type represents ...
Carbon addition in the form of plant litter or root exudates weakly affected relative growth of taxa (p = 0.09) compared to the soil type (p < 0.01). ... Clay minerals affect soil carbon ...
Carbon removed through surficial mineralization, for example, is challenging to account for and monitor because oceans, coasts and soils, where mine tailings and crushed rocks are spread, are open systems (as compared to a closed-system DAC plant). Observing the amount of carbon removed through subsurface mineralization also has …
Plant Mineral Nutrition Green plants take in and use carbon dioxide and water in photosynthesis, and the resulting glucose and other carbohydrates therefore contain the chemical elements carbon (C), hydrogen (H) and oxygen (O). Other classes of organic compound are built up using other elements. In addition to C, H and O, proteins contain ...
Elements mainly derived from soil in inorganic form are known as mineral elements.The three main sources of nutrients for plants are air, water, and soil. Elements obtained from air are known as non-mineral elements, such as carbon, oxygen, and hydrogen.Irrigation water is also a source of mineral elements from dissolved salts, …
Soil microorganisms help transform plant inputs into mineral-associated soil organic carbon (SOC) – the largest and slowest-cycling pool of organic carbon on land. However, the microbial traits that influence this process are widely debated. While current theory and biogeochemical models have settled on carbon-use efficiency (CUE) and …
Arbuscular mycorrhizal fungus (AMF) Rhizophagus intraradices, inoculated within the plant compartment, colonized roots of the host plant Avena barbata and grew across an air gap to reach the no-plant compartment.
