The burning of agricultural straw is a pressing environmental issue, and identifying effective strategies for the rational utilization of straw resources is decisive for achieving sustainable development. Owing to its high carbon content and exceptional stability, straw biochar produced via pyrolysis has emerged as a key focus in multidisciplinary...

Context: Increasing global demand for wheat necessitates heightened the nitrogen (N) input. However, this amplifies nitrous oxide (N2O) emissions, impairing global climate change. Objectives: To address this dual challenge of meeting crop demands while curbing N2O emissions, a two-years (2022–2023) field study was carried out in Central University...

The world emphasizing economic progress has degenerated its existing natural resources through overexploitation and exhausting anthropogenic activities. Water, a critical natural resource, has gone through various degrees of deterioration where metal toxicity is one of the most amplified sectors. Several publications have articulated the changes in...

Nitrous oxide (N 2 O) is considered a major contributor to global climate change in addition to carbon dioxide and methane. A significant quantity of N 2 O emission originates from agriculture, largely from high rates of fertiliser application. We studied N 2 O emissions from wheat field to evaluate the effect of different forms of fertilisers and...

Nitrous oxide is a greenhouse gas with high global warming potential emitted from agricultural sources. The effects of tillage practices and different levels of N fertiliser on seasonal fluxes of N 2 O were investigated in a field planted with the wheat variety Sonalika. The experiment was conducted during 2012-13 and 2013-14 under conventional til...

We investigated nitrous oxide (N 2 O) emission from an irrigated rice field over two years to evaluate the management of nitrogenous fertiliser and its effect on reducing emissions. Four forms of nitrogenous fertilisers: NPK at the recommended application rate, starch-urea matrix (SUM) + PK, neem-coated urea + PK and urea alone (urea without coatin...

Agricultural tillage practices and fertilizer play an important role in production and consumption of greenhouse gases (GHGs), which contribute to global climate change. Nitrous oxide (N 2 O) is a major GHG with high global warming potential produced by agricultural systems. This study assessed the yield and N 2 O emission from rice cropping system...

Agricultural soil acts as a source and sink of important greenhouse gases (GHGs) like methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2). Rice paddies have been a major concern to scientific community, because they produce the threatening and long-lasting GHGs mainly CH4 and N2O. Around 30% and 11% of global agricultural CH4 and N2O, resp...

In the modern era, due to urbanization, industrialization, and anthropogenic activities in the catchment, greenhouse gas (GHG; CO2, CH4, and N2O) emissions from freshwater ecosystems received scientific attention because of global warming and future climate impacts. A developing country like India contributes a huge share (4% of global) of GHGs fro...

Nitrogen (N) application to agricultural fields warrants curtailing nitrous oxide (N2O) emission and ammonia (NH3) volatilization for improved use efficiency with a less environmental footprint of N. As a means of mitigating N2O emissions, the efficacy of nitrification inhibitors (NIs) is well established but the efficacy of NIs in reducing NH3 vol...

The world entering the Anthropocene is highly witnessed through changes observed in Earth’s natural processes. The most important events are the climate change and global warming. Since industrialization, there has been an increment in average global temperature by ~10C as a consequence of increased rate of greenhouse gases (GHGs) emission. Phen...

Metal recycling is drawing high interest in the context declining natural resources and the future circular economy. Smelter dust from copper extraction plants contains copper (Cu), which is both an economic loss and a pollution issue. There is therefore a need for techniques to recover Cu from ultrafine dust. Here we tested sulfation roasting, wat...

Environmental contamination is one of the paramount concerns engulfing the entire world. Being nondegradable in nature, heavy metals (e.g., Ni, Cd, Cu, As, Hg, and Pb) are significant pollutants of soil and aquatic ecosystems. Although numerous technologies have been employed to remove toxic metals from contaminated sites, there is still need for m...

The burgeoning population and continuous increase in developmental activities are the major cause of rampant release of numerous environmental contaminants. These contaminants pollute the soil, air and water and ultimately enter the food chain. Several physical, chemical and biological techniques have been developed to remove these contaminants; ho...

Wetlands are one of the most productive ecosystems that support diverse habitats and biodiversity and are known for its various ecosystem goods and services. About half of global wetlands have found to be lost, and the conditions of remaining wetlands are deteriorating due to natural as well as anthropogenic cause. The negative economic, social, an...

This work dealt with the determination of the suitability of sorption of Volatile Organic Compounds (VOCs) on biochars prepared from neem, sugarcane and bamboo feedstocks. Six different VOCs namely benzene, toluene, methyl chloride, xylene, chloroform and carbon tetrachloride were used in a laboratory-scale set-up on non-activated biochars prepared...

Nonferrous metallurgical wastes like tailings, dross, dust, etc. are the potential resource of metals values. The technologies for recovery of valuable metals from these waste materials are under development. New recycling concept for metal-containing waste is developed to turn waste into a valuable resource and valorizing of the waste and residue...

Identification of the combination of tillage and N fertilization practices that reduce agricultural Nitrous oxide (N 2 O) emissions while maintaining productivity is strongly required in the Indian subcontinent. This study investigated the effects of tillage in combination with different levels of nitrogen fertilizer on N 2 O emissions from a rice...

Global climate change is one of the most prominent and complex environmental problems caused by increasing concentrations of atmospheric greenhouse gases. Rice paddies are an important anthropo-genic source of nitrous oxide (N 2 O), a greenhouse gas approximately 298 times stronger than carbon dioxide. Identifying a suitable mitigation method for N...

Amendment of local organic residues has been gaining worldwide attention for mitigation of agricultural greenhouse gases. Four treatments having different C-N ratios, including conventional Nitrogenous fertilizer (NPK), Cow dung (C:N = 25:1), Rice straw (C:N = 41:1) and Poultry manure (C:N = 15:1) were applied in the field to measure nitrous oxide...
