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...

On the rejuvenation of tropical Iaterttes by the incorporation of basalt dust

O. D'HOTMAN DE VILLIERS ABSTRACT: 1. The work of N. Craig and P. Halais of the. Reoherches Station as well as our own research on the soils and climates of the island, having amply shown that our soils of the wet regions are in an extreme state of climatic poor, we have the idea of regenerating them by incorporating powdered basalt. 2. This idea that has worried us for several years and which seems to us to be the logical focus of the genetic study of tropical soils, will bring, we are convinced, a happy revolution in soil science under climates where atmospheric agents are the cause of a deep decomposition by hydrolysis and a rapid exhaustion ...

Further results of studies on the rejuvenation of exhausted soils in humid districts by incorporating basalt dust.

O. D’Hotman de Villiers ABSTRACT: Results are republished of the 1938-41 experiments conducted in Mauritius with powdered basalt and heavy NPK fertilizer applications on sugar-cane crops grown in exhausted lateritic soil. With these are compared the results of the 2nd series of experiments (1944-47) on the same plots, in which, after a bare fallow of 23 months, moderate N and minimum P and K applications were combined with 10 metric tons/arpent of powdered basalt. The 1937 basalt dressings had been 10, 30 and 90 metric tons. Results show a striking residual benefit, especially from the highest basalt application, affecting both cane and sugar ...
