Urea is a common fertilizer in delayed‐flood rice production in the United States, and its use worldwide has increased dramatically in recent decades. This study aimed to directly quantify urea‐N persistence in floodwater and soil used for rice production. We conducted a set of three laboratory experiments to investigate urea‐N presence in the floodwater and soil. Untreated urea was applied to dry or wet soil and flooded immediately or urea treated with the urease inhibitor N‐(n‐butyl… 
Vertical distribution of fertilizer nitrogen from surface water flooding of a silt loam and clay soil used for rice production
Nitrogen (N) fertilizer retention and short‐term vertical redistribution into soil affect N balance and N‐use efficiency in rice (Oryza sativa L.) production systems. A series of experiments was
Ammonia Volatilization, Rice Yield, and Nitrogen Uptake Responses to Simulated Rainfall and Urease Inhibitor
The effect of rainfall between urea application and flood establishment on rice (Oryza sativa L.) grain yield has not been studied. We compared the effects of simulated rainfall amount and
Nitrogen Source Effects on Methane Emissions From Drill-Seeded, Delayed-Flood Rice Production
ABSTRACT Rice (Oryza sativa L.) cultivation is unique compared with the production of most other upland row crops in that rice is typically produced under flooded-soil conditions, which can result in
Long-term urea fertilization alters the composition and increases the abundance of soil ureolytic bacterial communities in an upland soil
TLDR
The results suggest that long-term intensive urea fertilization may increase the risk of N loss through ammonia volatilization and increase therisk of soil degradation due to the collapse of soil microbial diversity.
Influence of urease inhibitor on mineral nitrogen content in soil and productivity of winter wheat
The research was performed in 2019-2020 LAMMC at Rumokai Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry. The soil was calcaric luvisol, the granulometric

Nitrogen Fertilizer Sources and Timing before Flooding Dry‐Seeded, Delayed‐Flood Rice
Urea is the primary N source used for the large preflood N application in delayed-Rood rice (Oryza sativa L.) production in the southern United States. Urea is prone to substantial NH 3

Urea transformation was studied under a laboratory-simulated flooded soil condition, where the soil columns were preincubated for 3 months with 2 cm of standing water. Urea distributions in the

The immediate profitability and long-term sustainability of domestic crop production have been threatened by increasing N fertilizer costs. Currently, there is no soil test which can accurately
Escalating Worldwide use of Urea – A Global Change Contributing to Coastal Eutrophication
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.
Uptake of urea by estuarine bacteria
TLDR
It is demonstrated that urea uptake rates by estuarine bacteria are variable and often unpredictable, but occasionally, urea take-up can be of importance similar to NH 4 + and DFAA.
THE EFFECT OF SOIL ENVIRONMENT AND FERTILIZER MODIFICATIONS ON THE RATE OF UREA HYDROLYSIS
As part of an effort to model the behavior of urea by computer simulation, we studied the problems associated with modeling urea hydrolysis. Incubation experiments with a variety of soils were used
Urease activity in cultures and field populations of the toxic dinoflagellate Alexandrium
TLDR
It is demonstrated that axenic laboratory cultures of the toxic dinoflagellate, Alexandrium fundyense strain CB301A and A. catenella strain TN9A were able to grow on urea as a sole nitrogen source in the presence of nickel, which suggests that these Alexandrium species hydrolyze urea into ammonia with the enzyme urease rather than adenosine triphosphate urea amidolyase.
Algal growth on organic compounds as nitrogen sources
TLDR
The results are consistent with the proposition that components of the DON pool are not only an important potential, direct or indirect N source for phytoplankton, but also that different algal species can exploit these sources with varying capabilities so that different N substrates may selectively stimulate the development of dominantAlgal species.
Utilization of Urea by Some Marine PHYTOPLANKTERS1
TLDR
It appears, from data on natural urea concentrations and urea uptake rates by S. costata, that urea can be ,a significant N source for at least one common inshore phytoplankter and at least three offshore marine phy toplankton can grow as rapidly on urea as on nitrate or ammonia.
