While the global increase in the use of nitrogen-based fertilizers has been well recognized, another change in fertilizer usage has simultaneously occurred: a shift toward urea-based products. Worldwide use of urea has increased more than 100-fold in the past 4 decades and now constitutes >50% of global nitrogenous fertilizer usage. Global urea usage extends beyond agricultural applications; urea is also used extensively in animal feeds and in manufacturing processes. This change has occurred… 
Organic Nitrogen Runoff in Coastal Marshes: Effects on Ecosystem Denitrification
Since the 1970s, a shift from inorganic to organic nitrogen-based fertilizer has occurred worldwide, and now urea constitutes greater than 50 % of the global nitrogenous fertilizer usage. As a
Distribution and regulation of urea in lakes of central North America
Summary 1. Urea accounts for ∼50% of global nitrogen (N)-based fertiliser; however, little is known of the factors regulating its distribution and abundance in freshwaters. Improved understanding
Persistence and Surface Transport of Urea-Nitrogen: A Rainfall Simulation Study.
TLDR
This rainfall simulation study sought to assess the potential for different N fertilizers and manures to contribute to urea in runoff from a Coastal Plain soil on the Eastern Shore of Maryland and highlighted the potential of simple management options, such as shallow incorporation or timing, to greatly reduce urea runoff losses.
Distribution and regulation of urea in lakes of central North
SUMMARY 1. Urea accounts for � 50% of global nitrogen (N)-based fertiliser; however, little is known of the factors regulating its distribution and abundance in freshwaters. Improved understanding of
From hogs to HABs: impacts of industrial farming in the US on nitrogen and phosphorus and greenhouse gas pollution

TLDR
How nutrient inputs—from fertilizer and CAFOs—as well as atmospheric NH3 and greenhouse gas emissions, are changing regionally within the US and how these changes compare with nutrient inputs from human wastewater is provided.
Nitrogen in the Yaqui Valley: Sources, Transfers, and Consequences
In nitrogen fertilizer management, as in so many other ways, the Yaqui Valley represents a microcosm for the study of changes that are happening all over the world. Over the last thirty years,
Fertilizers and nitrate pollution of surface and ground water: an increasingly pervasive global problem
Nitrate pollution of ground and surface water bodies all over the world is generally linked with continually increasing global fertilizer nitrogen (N) use. But after 1990, with more fertilizer N
Urea Release by Intermittently Saturated Sediments from a Coastal Agricultural Landscape.
TLDR
It is postulate that concentrations of urea-N in ditches that greatly exceed environmental thresholds are mediated by biological production in sediments and release to stagnant surface water, which could elevate the risk of harmful algal blooms downstream in receiving waters despite the dilution effect.
Differential Drawdown of Ammonium, Nitrate, and Urea by Freshwater Chlorophytes and Cyanobacteria1
TLDR
The findings support the emerging urea–cyanoHAB link and the potential importance of urea in freshwater eutrophication and the need to understand how urea influences phytoplankton community composition may be instrumental in predicting bloom dynamics.

Concentrations of dissolved urea were monitored in several Chesapeake Bay tributaries from 1998 to 2002. Urea is a commonly used agricultural fertilizer and is also a breakdown product of poultry
Agricultural runoff fuels large phytoplankton blooms in vulnerable areas of the ocean
TLDR
It is demonstrated that nitrogen-deficient areas of the tropical and subtropical oceans are acutely vulnerable to nitrogen pollution, and it is projected that by the year 2050, 27–59% of all nitrogen fertilizer will be applied in developing regions located upstream of nitrogen- deficient marine ecosystems.

Significance of bacteria in urea dynamics in coastal surface waters
TLDR
The significance of bacteria as urea producers should be incorporated into models of nitrogen regeneration in surface waters, as in typical seawater samples, which have >l00 nM urea, the bacterial ureolysis system is always near-saturated.

Abstract There is a need in the marine research and management communities for a clear operational definition of the term, eutrophication. I propose the following: This definition is consistent with

TLDR
The potential for different sources of N, including DON, to stimulate differ- ent components of the algal community, and for the phytoplankton and bacteria to respond differently to N and P is demonstrated.
