Nitrogen fertilizer is essential for boosting agricultural yields and food production. However, agricultural subsidies often drive the inefficient application of fertilizer, leading to significant costs for farms, the environment, and economies. Scientific evidence indicates that nitrogen...

Synthetic fertilizers are essential to sustaining the world's population, but their production is responsible for 1.8-2.4 percent of global greenhouse gas emissions. Clean hydrogen holds growing potential (amid falling costs) to decarbonize fertilizer production. Hydrogen produces synthetic...

Reactive nitrogen (N) and phosphorus (P) pollution in Germany is mainly caused by production of cattle meat and milk, which is mostly consumed domestically. This pollution comes at a high external costs not yet addressed by current policies. We explore scenarios where reduced domestic cattle...

Seasonal variation in intensive agricultural land use patterns and its spatial scale effects on water nitrogen (N) and phosphorus (P) concentrations in watersheds have always been major concerns. However, the relationships and contributions of the important land use metrics to the pond water N...

Approximately one-third of all food produced globally goes to waste, promoting a growing demand to recycle and recover wasted nutrients using sustainable waste management technologies such as composting and anaerobic digestion. Organic end-products from composting and anaerobic digestion have...

In this study, the effects of sawdust + hulls (CK) and rice straw stalks + mushroom waste (T1) as auxiliary materials on nitrogen as well as microbial structure in the composting process when composted with chicken manure were investigated. At the end of composting, the nitrogen loss of T1 was...

Nitrogen pollution in medium-to-small rivers often brings about eutrophication to lakes. In this work, a composite technique consisting of retention pond (RP)-subsurface flow constructed wetland (SFCW)-stabilization pond (SP) was proposed in the present study. Results showed that RP-SFCW-SP can...

Nitrogen (N) is essential for crop growth and development under stress. The photosynthetic capacity of crops depends on the leaf N content (Na ), and leaf N allocation is an important factor affecting net photosynthetic rate (Pn ). However, the relationship between N supply and leaf N allocation...

Dryland ecosystems are generally drought-stressed and have low soil fertility. While the negative effects of drought on vegetation productivity are undisputed, it is unclear whether drought limits vegetation productivity alone or in combination with nitrogen (N) deficiency. To address this...

Resource recovery from wastewater is a key element for the effective implementation of circular economy in wastewater treatment plants (WWTPs). Usually, biological nitrification-denitrification processes are used in WWTPs to remove nitrogen from wastewater to protect the receiving aquatic...

Global atmospheric nitrogen (N) deposition have profound effects on terrestrial ecosystems. This study synthesized data from 54 papers and carried out a meta-analysis of experimental N-addition effects on 14 variables related to soil dissolved organic carbon and N (DOC and DON) dynamics....

Straw returning has been widely used as nitrogen (N) reduction measure in the North China Plain in recent years. But, little is known of the optimal plant density and N application rate of cotton under straw returning by now. In the present study, a short season cotton SCRC66 was used to study...

Plastic film mulching and gravel mulching in combination with fertilization are widely used to increase crop yields and water use efficiency (WUE) in arid and semi-arid areas, but soil surface mulching may stimulate soil organic carbon (SOC) mineralization, therefore, film mulching with manure...

Plastisphere refers to biofilm forming on microplastics (MPs) surface, but the difference in microbial communities between pelagic and benthic plastisphere and their subsequent functions especially driving biogeochemical cycle is rarely studied. Here, MPs were incubated for 28 d in pelagic...

Soil nitrogen (N) status is pivotal information for evaluating the role of the forest N cycle in forest function evolution with environmental changes. However, soil N levels and processes in forests receiving high anthropogenic N inputs remain less investigated, which hinders understanding the...

Herein, the decomposition temperatures and gases of nitrogen species formed in carbon materials were investigated via high-temperature temperature-programmed desorption (TPD) analysis of nitrogen-doped carbon with a shell-like structure of several layers of graphene as a model material, and the...

Nitrogen, in practice, has been an integral input component in our food production system. The application of synthetic nitrogen in agriculture, which was essential with high yield varieties, has been moving parallel since green revolution. Amendment and regulation of agriculture related acts,...

Lightning provides nitrogen fixation that fertilizes crops, but there have been no estimates on how this naturally provided input affects actual production and incentivizes farm behaviors. Based on a decades-long panel of US counties with geo-referenced lightning activities, I find lightning...

The nitrogen management on the Romanian permanent grasslands is dependent on various factors, but the traditional practices and agri-environment EU funded payment schemes are playing the most important roles. At the same time, policies and farmers are mainly acting against reducing the nitrogen...

An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0,...

Tef is one of the mostly important food grain sources of livelihood for farmers of the Aneded district in North Western Ethiopia. Nevertheless, the productivity of the crop is noticeably low due to limited use of improved variety and inappropriate use of rate of nitrogen fertilizer. Therefore,...

The fallout of nitrogen pollution is considered one of the largest global externalities facing the world, impacting air, water, soil, and human health. This paper combines data from the Demographic and Health Survey data set across India, Vietnam, and 33 African countries to analyze the causal...

Environmental policies are becoming an important part of agricultural policy portfolio in the EU, which is binding on Croatia. This paper seeks to evaluate potential sectoral effects of several nitrogen pollution reduction policy measures within CGE model for Croatia. Finding appropriate...

The fallout of nitrogen pollution is considered one of the largest global externalities facing the world, impacting air, water, soil, and human health. This paper combines data from the Demographic and Health Survey data set across India, Vietnam, and 33 African countries to analyze the causal...

The aim of this research was to determine the impact of various nitrogen fertilization systems in soya cultivation on quality and quantity of crop, as well as to examine the economic aspects of sustainable farming. The study was based on research carried out in the Variety Assessment Research...

All the scenarios and models made up by the most titled scientists in biology, agriculture, geophysics, and human health prove that the four main resources of the existence of the biosphere are so polluted that it is a matter of time until a major collapse of human existence occurs. The problem...
