Enhancement of Biochar Carbon Sequestration Through Mineral Regulation: Effects and Mechanisms
Fan Yang, Pengxiao Gao, Lin Chi, Zhongyu Gao, Yajun Wang, Liu Luo, Bo Liu, Xinyue Liu, Jingke Sima
ABSTRACT:
The conversion of waste biomass into biochar through inert pyrolysis represents a promising strategy for carbon sequestration. However, biochar production is often accompanied by the release of small molecular chemical substances during pyrolysis, and the resulting biochar is susceptible to environmental degradation. To enhance the carbon retention rate of biochar during pyrolysis and its stability in the environment, this study explored the incorporation of various metal soluble salts (CaCl2, Ca(H2PO4)2, MgCl2, FeCl3) and clay minerals ...
Long-term trends of streamwater chemistry in an agricultural watershed: Effects of anthropogenic and climatic factors
Fengchao Sun, Rob A. Rioux, William A. Miller-Brown, Bibek Shrestha, James B. Shanley, Noah J. Planavsky, Peter A. Raymond, James E. Saiers
ABSTRACT:
The chemistry of headwater streams is a key indicator of the health of riparian zones and surrounding terrestrial ecosystems. This chemistry is shaped by biogeochemical processes, including chemical weathering, and anthropogenic activities that interact with one another and are sensitive to climate. Elucidating trends in streamwater chemistry and the drivers that underpin them is essential for informing land-management decisions and anticipating water-quality issues that may affect downstream ...
Supplementing Enhanced Weathering With Organic Amendments Accelerates the Net Climate Benefit of Soil Amendments in Rangeland Soils
Tyler L. Anthony, Andrew R. Jones, Whendee L. Silver
ABSTRACT:
Carbon dioxide (CO2) removal (carbon dioxide removal (CDR)) that combines decreased greenhouse gas emissions with atmospheric CO2 reduction is needed to limit climate change. Enhanced rock weathering (ERW) of ground silicate minerals is an emerging CDR technology with the potential to decrease atmospheric CO2. However, there are few multi-year field studies and considerable uncertainty in field-rates of ERW. We explored combining finely ground metabasaltic rock with other soil CDR technologies (compost and biochar amendments) to stimulate carbon (C) sequestration. The combined ground ...
Micronutrients and contaminants in the grazing and agricultural soils of Kashmir Valley, India
Ishfaq Mir
ABSTRACT:
Soil plays a critical role in determining the food nutrition at the base of the food chain, which makes it essential for food safety. This study demonstrates how micronutrient deficiencies and pollution from hazardous elements may affect crop productivity as well as human and animal health. In the Kashmir valley’s Bandipora-Ganderbal region, 200 top soils were examined to ascertain the toxicity risks and trace element deficiencies. With mean values of 44,759 ± 6072, 120 ± 23, 114 ± 18, 89 ± 22, 44 ± 8, 33 ± 7, 23 ± 4, 19 ± 4, and 11 ± 5 respectively, the concentrations (mg kg⁻¹) vary from Fe: 31,326 to 77,420, ...
Nature based solutions in soil restoration for improving agricultural productivity
Kancheti Mrunalini, Biswaranjan Behera, Somasundaram Jayaraman, Purushothaman Abhilash, Pradeep Dubey, G. Narayanaswamy, J.V.N.S Prasad, Kv Rao, Pandian Krishnan, Pratibha Gudapaty, Srinivasrao Ch
ABSTRACT:
Soil is a living and dynamic body, which is prone to degradation under conventional agricultural practices. Healthy soil is one of the most important pillars of sustainability as it delivers several ecosystem services along with its control on microbial activity, nutrient recycling, and decomposition. Nature-based solutions can play an important role in restoring soil quality for enhanced agricultural productivity and sustainabili...
In-field carbon dioxide removal via weathering of crushed basalt applied to acidic tropical agricultural soil
Fredrick J. Holden, Kalu Davies, Michael I. Bird, Ruby Hume, Hannah Green, David J. Beerling, Paul N. Nelson
ABSTRACT:
Enhanced weathering (EW) of silicate rocks such as basalt provides a potential carbon dioxide removal (CDR) technology for combatting climate change. Modelling and mesocosm studies suggest significant CDR via EW but there are few field studies. This study aimed to directly measure in-field CDR via EW of basalt applied to sugarcane on acidic (pH 5.8, 0–0.25 m) Ultisol in tropical northeastern Australia, where weathering potential is high. Coarsely crushed basalt produced as a byproduct of gravel manufacture (<5 mm) was ...
