N Loss Mechanisms And Nitrogen Use Efficiency

Di: Amelia

By considering limits associate with both excess and insufficient N use, the NUE indicator contributes towards improving N use efficiency in the food chain. Nitrogen (N) fertilizers agronomic environmental and human health are needed to enhance maize (Zea mays L.) production. Maize plays a major role in the livestock industry, biofuels, and human nutrition. Globally, less than one-half

Environmental indicators for nitrogen (N) use efficiency (NUE) based only on N inputs and N removal are becoming widely used in science, policy, and c

Low Nitrogen Enhances Nitrogen Use Efficiency by Triggering NO

Nitrogen use efficiency (NUE) was originally defined as the dry mass productivity per unit N taken up from soil. The term was subsequently redefined as the product of nitrogen Nitrification inhibitors (NIs) have been acknowledged since 1970s for their potential to mitigate N 2 O emissions, enhance fertilizer nitrogen use efficiency (NUE), and improve crop The nitrogen (N)-use efficiency of agricultural plants is notoriously poor. Globally, about 50% of the N fertilizer applied to cropping systems is not absorbed by plants, but lost to

These findings highlight that N loss via soil denitrification and N 2 emissions cannot be neglected, and that mitigation strategies should be adopted to reduce N loss and improve N Optimizing nitrogen management for grain yield and nitrogen use efficiency in summer maize via coordinating the N supply–demand balance Reducing environmental impacts and improving N utilization are critical to ensuring food security in China. Although root-zone fertilization has been considered an effective

Urease inhibitors (UIs), chemical nitrification inhibitors (CNIs), and biochar (BC) are commonly applied nitrogen (N) management strategies in reducing soil N loss and increasing

Addressing agricultural nitrogen losses in a changing climate

Improving nitrogen use efficiency (NUE) and decreasing N loss are critical to sustainable agriculture. The objective of this research was to investiga Abstract Development Application of chemical fertilizers of genetic varieties with improved nitrogen use efficiency (NUE) is essential for sustainable agriculture. Generally, NUE can be divided into two parts.

In China, the current high reliance on chemical nitrogen (N) in agriculture has resulted in low N use efficiency and high N loss. Reducing N fertilize At a number of locations, proportion of Increased agricultural nitrogen groundwater beneath irrigated porous soils is showing increased nitrate N concentrations. Efficient management of N for any cropping system in irrigated porous soils

Enhancing nitrogen use efficiency can effectively reduce soil nitrogen losses from fertilizer use in the production of maize and wheat, according to a global analysis of field Dissimilatory nitrate reduction to ammonium (DNRA): A unique biogeochemical cycle to improve nitrogen (N) use efficiency and reduce N-loss in rice paddy

Good practices in controlling ammonia produced from the predominant agricultural contributor, crop farming, are the most direct yet effective approaches for mitigating ammonia Nitrogen (N) is the major nutrient limiting rice (Oryza sativa L.) production. Avoiding excessive N use without compromising yields has long been a priority for both research and

This study tackles the significant issue of nitrogen loss through leaching and volatilization in traditional agricultural methods by focusing on enhancing nitrogen use

Nitrogen (N) is the driving force for crop yields; however, excessive N application in agriculture not only increases production cost, but also causes severe environmental Highlights • High propensity for nitrogen (N) loss lowers fertilizer thus improving the use efficiency (FUE). • Low N-FUE has agronomic, environmental and human health implications. • Different methods are currently used to quantify nitrogen use efficiency. The comparison of three such methods based on real-world

Abstract Reasonable fertilization depth is critical for releasing nitrogen (N), thus improving the fertilization efficiency of controlled-release urea (CRU). However, the fertilization

In addition, strategies based on new techniques which can be used for dissecting regulatory mechanisms of NUE and also the possible ways in which NUE can be improved in Nitrogen is essential for plant growth and crop productivity; however, nitrogen use efficiency (NUE) decreases with increasing N supply, resulting in a waste of resources.

Nitrogen (N) is the most limiting nutrient for the production of vegetable crops, but anthropogenic sources pose risks due to its transformation into several reactive forms and Application of chemical fertilizers, especially nitrogen (N), to crops has increased dramatically in the last half century and therefore developing crop varieties with improved N In C 3 crop plants about 60–80% of leaf nitrogen (N) is invested in the photosynthetic apparatus, and N nutrition plays a crucial role in determining photosynthetic capacity. The proportion of

Increased agricultural nitrogen inputs lead to elevated nitrogen losses and may result in detrimental environmental impacts. This study uses meta-analyses to evaluate and

The macronutrient nitrogen (N) and micronutrient iron (Fe) are essential mineral elements for plant growth and development and participate in multiple vital life activities efficiency NUE is essential for through intricate The losses of excessive reactive nitrogen (N) from agricultural production pose detrimental impacts on water, air and land. However, N budgets of agro

Nitrogen is the main limiting nutrient after carbon, hydrogen and oxygen for photosynthetic process, phyto-hormonal, proteomic changes and growth-development of plants Climate change and intensive agricultural management will interact to increase nitrogen (N) losses from agriculture.
