“…Various researchers have confirmed that orchards like citrus, wine grape, apple, olive, peach, hazelnut, and orange could be a substantial sink for atmospheric carbon (Liguori et al, 2009;Granata et al, 2020). Similarly, any agricultural practices, like the use of organic manures or AM fungi, may act as carbon sinks (Shi et al, 2017;Sharma et al, 2018;Verbruggen et al, 2021). Several studies have shown that the application of organic manures improves the physicochemical properties of soil (Evanylo et al, 2008;Bravo et al, 2012;Sharma et al, 2018;Sharma et al, 2021) and ameliorates root development (Baldi et al, 2010;Sarita et al, 2019).…”

Nowadays, rapid increases in anthropogenic activities have resulted in increased greenhouse gases (GHGs; CO2, CH4, N2O) release in the atmosphere, resulting in increased global mean temperature, aberrant precipitation patterns, and several other climate changes that affect ecological and human lives on this planet. This article reviews the adaptation and mitigation of climate change by assessing carbon capture, storage, and utilization by fruit crops. Perennial plants in forests, fruit orchards, and grasslands are efficient sinks of atmospheric carbon, whereas field crops are a great source of GHG due to soil disturbance, emission of CH4 and/or N2O from burning straw, and field management involving direct (fuel) or indirect (chemicals) emissions from fossil fuels. Thus, there is a need to establish sustainable agricultural systems that can minimize emissions and are capable of sequestering carbon within the atmosphere. Fruit orchards and vineyards have great structural characteristics, such as long life cycle; permanent organs such as trunk, branches, and roots; null soil tillage (preserving soil organic matter); high quality and yield, which allow them to accumulate a significant amount of carbon. Hence, the fruit plants have significant potential to sequester carbon in the atmosphere. However, the efficiency of carbon sequestration by different fruit crops and their management systems may vary due to their growth and development patterns, physiological behavior, biomass accumulation, and environmental factors.

“…The weathering rate of silicate minerals depends on several abiotic and biotic factors. Specifically, it increases with increasing surface area (Strefler et al, 2018), while higher pH, lower temperature, and precipitation rates, along with varying soil CO 2 partial pressure can negatively affect the weathering rates (Verbruggen et al, 2021). Biogeochemical and biomechanical activity can also affect weathering rates in soils (Vicca et al, 2022).…”

“…Biogeochemical and biomechanical activity can also affect weathering rates in soils (Vicca et al, 2022). Plants may enhance silicate mineral weathering in soils through their roots and associated mycorrhizal fungi, via diverse mechanisms such as the release of organic acids (Taylor et al, 2009;Thorley et al, 2015;Verbruggen et al, 2021) and secretion of acids or stimulation of acid-generating nitrification by nitrogen-fixing plants (Bolan et al, 1991;Epihov et al, 2017;Perakis and Pett-Ridge, 2019). Invertebrates in soil also contribute to weathering, both chemically, through the action of gut microbiota, and mechanically by biopedturbation (Van Groenigen et al, 2019;Vicca et al, 2022).…”

“…The associated benefits of applying silicate rock dust on soils could promote plant growth and survival rate, through replenishing soil nutrients (Leonardos et al, 1987;Hartmann et al, 2013;Anda et al, 2015) and through increasing plant resilience to external stresses (Beerling et al, 2018). Moreover, mycorrhizal fungi associated with plant roots are one of the main drivers of silicate rock weathering in soils (Taylor et al, 2009;Thorley et al, 2015;Verbruggen et al, 2021). Urban and brownfield soils also present certain advantages for soil enhanced weathering (Manning and Renforth, 2013).…”

Geochemical Negative Emissions Technologies: Part I. Review

et al. 2022

Over the previous two decades, a diverse array of geochemical negative emissions technologies (NETs) have been proposed, which use alkaline minerals for removing and permanently storing atmospheric carbon dioxide (CO2). Geochemical NETs include CO2 mineralization (methods which react alkaline minerals with CO2, producing solid carbonate minerals), enhanced weathering (dispersing alkaline minerals in the environment for CO2 drawdown) and ocean alkalinity enhancement (manipulation of ocean chemistry to remove CO2 from air as dissolved inorganic carbon). CO2 mineralization approaches include in situ (CO2 reacts with alkaline minerals in the Earth's subsurface), surficial (high surface area alkaline minerals found at the Earth's surface are reacted with air or CO2-bearing fluids), and ex situ (high surface area alkaline minerals are transported to sites of concentrated CO2 production). Geochemical NETS may also include an approach to direct air capture (DAC) that harnesses surficial mineralization reactions to remove CO2 from air, and produce concentrated CO2. Overall, these technologies are at an early stage of development with just a few subjected to field trials. In Part I of this work we have reviewed the current state of geochemical NETs, highlighting key features (mineral resources; processes; kinetics; storage durability; synergies with other NETs such as DAC, risks; limitations; co-benefits, environmental impacts and life-cycle assessment). The role of organisms and biological mechanisms in enhancing geochemical NETs is also explored. In Part II, a roadmap is presented to help catalyze the research, development, and deployment of geochemical NETs at the gigaton scale over the coming decades.

“…Given that mycorrhizal fungi depend on their host for C, their influence on ESW is likely to be strongly related to plant activity and plant C allocation. Depending on soil conditions, plants can allocate substantial amounts of C to mycorrhizal fungi (Ven et al, 2020), and thereby stimulate their weathering activity, increasing the release of P and other mineral elements from the silicate minerals (Verbruggen et al, 2021).…”

A number of negative emission technologies (NETs) have been proposed to actively remove CO 2 from the atmosphere, with enhanced silicate weathering (ESW) as a relatively new NET with considerable climate change mitigation potential. Models calibrated to ESW rates in lab experiments estimate the global potential for inorganic carbon sequestration by ESW at about 0.5-5 Gt CO 2 year −1 , suggesting ESW could be an important component of the future NETs mix. In real soils, however, weathering rates may differ strongly from lab conditions. Research on natural weathering has shown that biota such as plants, microbes, and macro-invertebrates can strongly affect weathering rates, but biotic effects were excluded from most ESW lab assessments. Moreover, ESW may alter soil organic carbon sequestration and greenhouse gas emissions by influencing physicochemical and biological processes, which holds the potential to perpetuate even larger negative emissions. Here, we argue that it is likely that the climate change mitigation effect of ESW will be governed by biological processes, emphasizing the need to put these processes on the agenda of this emerging research field.
