Marginal land conversion to perennial energy crops with biomass removal enhances soil carbon sequestration

However, the effects of perennial energy crop cultivation on soil organic carbon sequestration and its underlying mechanism in marginal land remain incomplete. In bulk and root zone, respectively, the naturally occurring 13C signature from soil to 60 cm depth was used to determine the energy crops' U201derived C. In the bulk zone, the mean residence time of old C was higher under switchgrass than Miscanthus in the switchgrass range of 0 to 0 u201360 cm, but in the root zone, the same was held at 0 u201320 cm. According to the partial least squares path model, perennial energy crop cultivation raises soil C stock by increasing C4u2010derived C input and reduced mineralization. In conclusion, marginal land conversion to perennial energy crops is a win-win for C sequestration to combat climate change and sustain the growing bioenergy industry with biomass supply.

The role of soil carbon sequestration in enhancing human resilience in tackling global crises including pandemics

In this context, agricultural production and nutritious foods are closely related to soil health and the diversity of their biome, which are reliant on organic carbon materials as a fuel and nutrient source. We describe pathways for how the loss of soil carbon from farming could be reversed by changes in our food systems. In addition to mitigating and adapting to climate change, we find that soil carbon plays a significant role in improving environmental and human health.

Estimating growth, loss and potential carbon sequestration of farmed kelp: a case study of Saccharina latissima at Strangford Lough, Northern Ireland

Many governments are evaluating marine carbon sequestration techniques for their ability to minimize climate change's adverse effects. This study found the potential carbon sequestration of cultivated macroalgae by determining the amount of biomass released into the environment from a kelp, Saccharina latissima farm in Strangford Lough, Northern Ireland, estimating the rate of carbon sequestration of cultivated macroalgae. Following blade failure, a mere 41% of the cultivated kelp's net primary productivity was lost before harvest, or equivalent to a total sequestered carbon equivalent for the site during the cultivation period. We calculated that a median of 4. 4 kg of carbon sequestered per 100 meters longline at the site during the cultivation period was lost prior to harvest. These findings are essential for those promoting the sustainable growth of the macroalgae cultivation industry in the region, and are highly relevant for the development of UN Sustainable Development Goal 13 and Goal 14.

Influence of Heterogeneous Caprock on the Safety of Carbon Sequestration and Carbon Displacement

We first selected the injection-production technique of fixed gas injection rate at the top of the reservoir and constant pressure oil production at the bottom of the reservoir in this paper. Secondly, the production of porosity and permeability in the caprock is investigated, and four designs of caprock models are established: homogeneous caprock, layered homogeneous caprock, heterogeneous caprock, and layered heterogeneous caprock. Finally, the intrusion quantity and migration characteristics of CO 2 in caprock of four schemes are investigated, as well as caprock distribution and caprock are determined, as well as pressure distribution caprock. In addition, the oil recovery ratio, geological CO 2 storage, and the amount of CO 2 intrusion in caprock under different injection-production conditions in this model are also investigated.

Estimating Biomass and Carbon Sequestration Capacity of Phragmites australis Using Remote Sensing and Growth Dynamics Modeling: A Case Study in Beijing Hanshiqiao Wetland Nature Reserve, China

In Beijing, China, the Hanshiqiyao Wetland Nature Reserve is a huge P. australis wetland and provides an excellent case study location for such a purpose in urban setting. The maximum AGB and below-ground biomass of P. australis in the HWNR is 2. 93 g m u22122, respectively, which are higher than the reported level from nearby sites with similar latitudes, presumably due to the high nutrient supply and more suitable floodplain conditions in the HWNR. The annual carbon sequestration capacity of P. australis in the HWNR was estimated to be 2040. 73 gC m U22122 yr u22121 yr, which was also highly dependent on nutrient availability, resulting in a 12% rise in the annual carbon sequestration capacity, which was also found to be highly dependent on nutrient availability. u22121 yr u22121 yr u22121 yr u22122 yr t u y t sequestration capacity u22121 t n u22121 n u22121 yr t u22121 yr u22121 yr u22121 u22122121 a u22121 u202121 u22121 u.

Conversion of degraded agricultural landscapes to a smallholder agroforestry system and carbon sequestration in drylands

U2013 Purpose This paper aims to provide the evidence on how carbon sequestration in terrestrial ecosystems may contribute to reduced atmospheric CO 2 levels by the use of appropriate cropping methods, such as agroforestry. Composite soil samples were collected from three soil depths for soil carbon analysis. U2013 -2013 There was a significant difference in vegetation and soil carbon stocks among the different land use/land cover types, according to the underlying data. The potential carbon stock was the highest in the vegetation discovered in sparsely planted land and in soil in bushland. The amount of sequestered carbon was found to be proportional to species diversity, tree number, and tree species. Among the various land use/land cover types, vegetation and soil carbon ratios showed a good relationship with soil and total carbon.

Carbon Sequestration in Support of the “4 per 1000” Initiative Using Compost and Stable Biochar from Hazelnut Shells and Sunflower Husks

The achievement of carbon freeness until 2050 would necessitate the deployment of negative carbon pollution controls such as the production and soil incorporation of biochar made from pyrolyzed plant-based residues. When the biomass was carbonized in a fixed bed reactor, in a rotary kiln, and in a screw reactor, the carbon sequestration potential of biochar from hazelnut shells and sunflower husks was determined. For all annual crop areas and orchards, an annual soil organic carbon increase of 2. 5 million tonnes C will be needed, with amendment rates of 2. 2 Mt C a u22121 for all vineyards and orchards. The study shows in principle that the application of compost and biochar mixtures for achieving the u201d target, but that additional soil management plans for sequestering C would be needed.

Microalgal-Based Carbon Sequestration by Converting LNG-Fired Waste CO 2 into Red Gold Astaxanthin: The Potential Applicability

To reduce the average global temperature, the combinatorial approach of anthropogenic activities and CO 2 sequestration is becoming a global research trend. Despite the debate regarding the quality and safety of the products in the food and feed industry, microalgae have been widely used to capture CO 2 from industrial flue gas. The flue gas-based bioproducts could be used for animal health-based biofuels in the future.

Effect of Hydraulic Retention Time on Carbon Sequestration during the Two-Stage Anammox Process

In a biological treatment process, hydraulic retention time has a certain effect on the reactor's operation. This paper examined the effect of HRT on carbon sequestration in a two-stage anaerobic ammonium oxidation process, using a partial nitrification reactor and an ammox reactor to determine the correct carbon sequestration operating conditions. The results of microbial analysis reveal that the carbon-fixing gene cbbL R1 was present in the sludge samples during the anammox and partial nitrification phases, as well as a Calvin cycle carbon sequestration pathway during the growth process.

Effect of Biowastes on Soil Remediation, Plant Productivity and Soil Organic Carbon Sequestration: A Review

High anthropogenic activities are inevitably contributing to soil erosion, so soil health and safety are becoming a significant concern. Biowastes, due to their high percentage of organic compounds, can be used to improve soil quality, plant growth, and microbial activity that leads to higher humus production. Increased carbon sequestration by biowaste use aids in combating climate change and global warming. Biowaste amendments soil growth and plant growth, which are linked to increases soil growth and plant growth caused by increases soil growth and plant growth as a result of an increase in shoot and root length, biomass production, grain yield, chlorophyll content, and decreased oxidative stress. However, biowaste application to soils is a debatable topic due to the potential negative effect of elevated heavy metal content and dangers of their incorporation in soils. In this article, we summarize the latest evidence on the effects of biowastes on soil remediation, plant growth, and soil organic carbon sequestration.
