Abstract:
... Burning crop residues is a common way to remove them during the final stages of crop ripening in China. To conduct research effectively, it is critical to reliably and quantitatively estimate the extent and location of a burned area. Here, we investigated three publicly available burned area products—MCD64A1, FireCCI 5.1, and the Copernicus Burnt Area—and evaluated their relative performance at es ...

Abstract:
... Crop residues are effective for the prevention of soil erosion. The crop residue cover (CRC) can be mapped by remote sensing. Different morphologies of crop residue will affect the spectral reflectance, reducing the accuracy of CRC estimation by multispectral data. However, the influence of residue morphology is not fully considered on the accuracy of CRC mapping using satellite images. In additio ...

Abstract:
... Crop residue input plays a central role in regulating soil organic carbon (SOC) storage. Ten long-term field experiments were used to ascertain the changes in SOC in response to differing rates of crop residues. The amount of C input from crop residues varied significantly between and within sites due to soil-environmental conditions, management and cropping systems. Initial SOC stocks ranged from ...

Abstract:
... The sustainable management of waste from agricultural crops represents an urgent challenge. One possible solution considers waste as possible secondary raw materials for specific uses. Among these, the use of agricultural waste as a product for the assembly of panels for the sound absorption of living environments represents a particularly suitable solution. In this study, the acoustic properties ...

Abstract:
... Air pollution has emerged as a leading global health risk in recent decades, where its health impacts are primarily focused on urban areas. In India, semi-urban and rural areas are also emerging as air pollution hotspots. As these regions are out of focus, the current study monitored air pollution (PM₂.₅) at a rural district of Punjab in North India and attempted to study the associated health imp ...

Abstract:
... The response of the carbon (C) cycle to global warming in terrestrial ecosystems is a major issue that must be considered when predicting future climate change. Due to warming simultaneously affects both vegetation and soil, therefore the response of soil organic carbon (SOC) has shown contradictory results in different warming experiments. A 7-year soil warming experiment using plastic film mulch ...

Abstract:
... Dilution ratios (DRs) and burning conditions obviously affect particle number size distributions (PNSD), chemical compositions, and mixing states. These impacts for domestic solid fuel burning were investigated. For honeycomb briquettes, total particle number emission factors (EFPN) under DR150 for flaming and smoldering were (7.1 ± 0.8) × 10¹⁵ and (19.6 ± 5.9) × 10¹⁶ particles kg–¹, respectively. ...

Abstract:
... Soil erosion in croplands has a strong impact on global carbon (C) cycle. Assessment of erosional effects on soil organic carbon (SOC) dynamics in agricultural soils suffers from the difficulty of distinguishing the erosional effects and complex interaction processes between erosion and C cycling. To simulate the effects of soil erosion, a plots experiment including six erosion levels (0, 5, 10, 2 ...

Abstract:
... Soil organic carbon (SOC) is closely tied to soil health. However, additional biological indicators may also provide insight about C dynamics and microbial activity. We used SOC and the other C indicators (potential C mineralization, permanganate oxidizable C, water extractable organic C, and β-glucosidase enzyme activity) from the North American Project to Evaluate Soil Health Measurements to exa ...

This study examines the key structural units present in water- and methanol-soluble organic carbon (WSOC, MSOC) fraction of OA from emission sources (traffic and biomass cooking) and an urban background location in India. Proton nuclear magnetic resonance (¹H NMR) spectroscopy was emplo ...

Abstract:
... Crop rotations and residue management contribute to the sustainability of the soil and environment and reduction of fertiliser use. However, appropriate crop and residue level combinations have yet to be determined to maximise productivity, while ensuring the preservation of soil resources in different agricultural production systems. The experiment evaluated production and soil chemical propertie ...

Abstract:
... Phosphorus (P) within crop residues is released to soils and thus is expected to partially replace the application of chemical P. However, whether and how P availability responds to a reduction in chemical P under crop residue mulching is still poorly understood.

Abstract:
... Accurate estimations of soil cover parameters (fractional coverage of crop residue [f cᵣ], crop [f c], and bare soil [f bₛ]) in croplands can assist in decision-making for agricultural management organisations and are important for understanding the interrelations between global changes and terrestrial ecosystems. In recent decades, optical remote sensing has been widely used for mapping f c, f cᵣ ...

Abstract:
... In vitro ruminal fermentation is considered an efficient way to degrade crop residue. To better understand the microbial communities and their functions during in vitro ruminal fermentation, the microbiome and short chain fatty acid (SCFA) production were investigated using the metagenomic sequencing and rumen simulation technique (RUSITEC) system. A total of 1677 metagenome-assembled genomes (MAG ...

Abstract:
... Climate change is expected with the ever rising human population on the planet earth. The different anthropogenic activities have resulted in increased levels of greenhouse gases (GHGs), higher temperatures, aberrant precipitation patterns, and other climate changes, calling for advanced restitution techniques. Renewable energy sources have gained momentum over the past few years under changing cl ...
... Modern agriculture has evolved technological innovations to sustain crop productivity. Recent advances in biorefinery technology use crop residue as feedstock, but this raises carbon sequestration concerns as biorefining utilizes carbon that would otherwise be returned to the soil thus causing a decline in crop productivity. Furthermore, biorefining generates abundant lignin waste that significant ...

Abstract:
... Fertilization practices change soil organic carbon content and distribution, which is relevant to crop rotation and soil aggregates. However, how fertilization management under corn–soybean rotation affects soil organic carbon and aggregate stability at different soil depths in Mollisols is unclear. The effects of 6–yr fertilization under corn–soybean rotation on aggregate stability, soil organic ...
... Although considerable knowledge exists on the impact of crop residues on soil N availability, information about their impact on nitrification specifically is lacking. The unique physiologies of ammonia oxidizing archaea (AOA) suggests their activities might respond differently to crop residue amendment compared to ammonia oxidizing bacteria (AOB). An incubation study was conducted on two widely di ...
... The impact of biochar on C storage and nutrient cycling when co-applied with other non-pyrolyzed organic amendments is still uncertain. Therefore, an incubation experiment for 120 days was conducted to understand the potential of biochar for C accretion and nutrient release when co-applied with non-pyrolyzed organic materials like crop residue (rice residue) and manure (animal manure). The results ...
