Geoengineering is a proposed action to manipulate Earth's climate in order to counteract global warming from anthropogenic greenhouse gas emissions. We investigate the potential of a specific geoengineering technique, carbon sequestration by artificially enhanced silicate weathering via the dissolution of olivine. This approach would not only operate against rising temperatures but would also o...

This study investigated the quantitative and qualitative attributes of liquid product biochar obtained from pyrolysis woody biomass (rubberwood sawdust (RWS)) non-woody biomasses (oil palm trunk (OPT) oil fronds (OPF)). The prepared was pyrolyzed at temperatures 500 °C, 550 600 °C by using an agitated bed reactor, then yields characteristics were determined. results showed that in respective ra...

Healthy soils are important to ensure satisfactory crop growth and yield. Poultry litter (PL), as an organic fertilizer, has proven supply the soil with essential macro micronutrients, enhance fertility, improve productivity. Integrating this treatment potential physical biological properties by increasing carbon, C. However, rapid decomposition mineralization of PL, particularly in hot humid s...

The paper analyzes nonlinear optimal control of integral–differential equations that describe the optimal management of a forest taking into account intra-species competition and carbon sequestration. The objective function includes the revenues from timber production, operational expenses, and the net benefits from carbon sequestration. A dual system is derived and a necessary extremum conditi...

The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...

The formation of soil inorganic carbon in saline–alkali lands is great significance for enhancing sequestration. As the mechanisms, addition to discovered abiotic microbial mechanisms remain unclear. To address this, microbes were isolated from farmland Yellow River Delta north China. Then, their capacity carbonate precipitation was determined. Ten strains obtained soil. Of these, seven (four b...

Compost amendments to grasslands have been proposed as a strategy to mitigate climate change through carbon (C) sequestration, yet little research exists exploring the net mitigation potential or the long-term impacts of this strategy. We used field data and the DAYCENT biogeochemical model to investigate the climate change mitigation potential of compost amendments to grasslands in California,...

Peatlands play an important role in the global carbon (C) cycle due to their large C storage potential. Their C sequestration rates, however, highly vary depending on climatic and geohydrological conditions. Transitional mires are often characterised by floating peat with infiltration of buffered groundwater or surface water. Sphagnum mosses grow on top, producing recalcitrant organic matter an...

The fresh water discharged by large rivers such as the Amazon is transported hundreds to thousands of kilometers away from the coast by surface plumes. The nutrients delivered by these river plumes contribute to enhanced primary production in the ocean, and the sinking flux of this new production results in carbon sequestration. Here, we report that the Amazon River plume supports N(2) fixation...

Abstract Background Nitrogen (N) deposition alters litter decomposition and soil carbon (C) sequestration by influencing the microbial community its enzyme activity. Natural atmospheric N comprises of inorganic (IN) organic (ON) compounds. However, most studies have focused on IN effect C cycling, whereas ON activity is poorly understood. Here we studied effects different forms externally suppl...
