Abstract Rice paddies account for ~9% or the world’s cropland area and are characterized by environmental conditions promoting soil organic carbon storage, methane emissions to a lesser extent nitrous oxide emissions. Here, we synthesize data from 612 sites across 51 countries estimate global stocks in paddy soils determine main factors affecting storage. Paddy (0–100 cm) contain 18 Pg worldwide. decrease with increasing mean annual temperature pH, whereas precipitation clay content had minor impacts. Meta-analysis shows that can be increased through several management practices. However, greenhouse gas mitigation storage is generally outweighed increases Our results emphasize key role of cycle, importance minimizing anthropogenic

Greenhouse gases emission from agricultural soil: A review

Journal of Agriculture and Food Research, Journal Year: 2023, Volume and Issue: 11, P. 100533 - 100533

Published: Feb. 16, 2023

The demand for agricultural goods is currently higher than it has ever been before due to the expansion of world population. This resulted in conversion grassland into areas, development high-energy-intensive agriculture production systems, and use additional chemical organic inputs systems. output greenhouse gases (GHGs) also increased same way. Carbon dioxide (CO2), Nitrous Oxide (N2O), Methane (CH4) most significant (GHGS) that are producing a variety disastrous consequences climate change. Despite fact CH4 N2O released smaller amounts CO2, they have larger Global Warming Potential CO2. analysis begins with an examination variables contribute gas emissions, which covers both inorganic factors (such as nitrogen, phosphorus, potassium fertilizers) (Animal manure, composted bio-solids, crop species). study underlines need more research intricate interactions physical, chemical, biological elements near future. Field crops other cereals, such legumes, oilseeds, vegetables, fruits, account amount (GHG) emissions. Precision may be viable option increasing efficiency. Optimal management practices should implemented farm field settings through methodical, site-specific approaches.

Management Strategies to Mitigate N2O Emissions in Agriculture

Life, Journal Year: 2022, Volume and Issue: 12(3), P. 439 - 439

The concentration of greenhouse gases (GHGs) in the atmosphere has been increasing since beginning industrial revolution. Nitrous oxide (N2O) is one mightiest GHGs, and agriculture main sources N2O emissions. In this paper, we reviewed mechanisms triggering emissions role agricultural practices their mitigation. amount produced from soil through combined processes nitrification denitrification profoundly influenced by temperature, moisture, carbon, nitrogen oxygen contents. These factors can be manipulated to a significant extent field management practices, influencing emission. relationships between occurrence regulating it are an important premise for devising mitigation strategies. Here, evaluated various options literature found that effectively reduced intervening on time method N supply (30–40%, with peaks up 80%), tillage irrigation (both non-univocal way), use amendments, such as biochar lime (up slow-release fertilizers and/or inhibitors 50%), plant treatment arbuscular mycorrhizal fungi 75%), appropriate crop rotations schemes integrated nutrient (in way). conclusion, acting (fertilizer type, dose, time, method, etc.) most straightforward way achieve reductions without compromising yields. However, tuning rest (tillage, irrigation, rotation, principles good also advisable, fetch abatement vs. risk unexpected rise, which incurred unwary management.

The greatest challenge for the agriculture sector in twenty-first century is to increase agricultural production feed burgeoning global population while maintaining soil health and integrity of agroecosystem. Currently, application biochar widely implemented as an effective means boosting sustainable having a negligible influence on ecosystems environment. In comparison traditional biochar, nano-biochar (nano-BC) boasts enhanced specific surface area, adsorption capacity, mobility properties within soil, allowing it promote properties, crop growth, environmental remediation. Additionally, carbon sequestration reduction methane nitrous oxide emissions from can be achieved with nano-BC applications, contributing climate change mitigation. Nonetheless, due cost-effectiveness, sustainability, friendliness, waste-derived may emerge most viable alternative conventional waste management strategies, circular bioeconomy broader goal achieving Sustainable Development Goals (SDGs). However, it's important note that research still its nascent stages. Potential risks, including toxicity aquatic terrestrial environments, necessitate extensive field investigations.

Although nitrogen (N) is the most limiting nutrient for agricultural production, its overuse associated with environmental pollution, increased concentration of greenhouse gases, and several human animal health implications. These implications are greatly affected by biochemical transformations losses N such as volatilization, leaching, runoff, denitrification. Half globally produced fertilizers used to grow three major cereals—rice, wheat, maize—and their current level recovery approximately 30–50%. The continuously increasing application fertilizers, despite lower cereals, can further intensify leftover N. To address these implications, improvement in use efficiency (NUE) adopting efficient agronomic practices modern breeding biotechnological tools developing cultivars requires immediate attention. Conventional marker-assisted selection methods be map quantitative trait loci, introgression elite germplasm leads creation better NUE.
