Mineral salt intake effects on faecal-N concentration and the volume and composition of beef cattle urine
(2018-01-01)
The effect of mineral salts on water ingestion and urine volume in cattle has been extensively studied. However, recently, this effect has been investigated as a potential mitigator of environmental aspects related to the ...
Ammonia volatilization in response to coated and conventional urea in maize crop fieldVolatilização de amônia utilizando ureia convencional e revestida na cultura do milho
(2019-05-01)
The properly measurement of gas emissions and nutrient availability to crops using technologies such as polymer-coated urea are required to monitored the possible nitrogen (N) fertilizer pollution in the environment. This ...
Emiliania huxleyi endures N-limitation with an efficient metabolic budgeting and effective ATP synthesis
(2014)
Abstract
Background
Global change will affect patterns of nutrient upwelling in marine environments, potentially becoming even stricter regulators of phytoplankton primary ...
Effect of nitrogen application rate on yield, forage quality, and animal performance in a tropical pasture
(2019-12-01)
A three-year-long field experiment was conducted in a continuous grazing system with a variable stocking rate to evaluate effects of increasing nitrogen levels in Marandu grass (Brachiaria brizantha Hochst ex A. Rich Stapf ...

Effects of supplementation with corn distillers’ dried grains on animal performance, nitrogen balance, and enteric CH4 emissions of young Nellore bulls fed a high-tropical forage diet
(2021-03-01)
The inclusion of corn-dried distillers’ grains (DDG) could be an alternative supplement to increase animal performance, nitrogen efficiency usage (NEU), and decrease enteric methane (CH4) emissions. Our goal was to determine ...
Nitrogen sensing and regulatory networks: It’s about time and space
(2024)
A plant's response to external and internal nitrogen signals/status relies on sensing and signaling mechanisms that operate across spatial and temporal dimensions. From a comprehensive systems biology perspective, this ...
Impact of replacing soybean meal in beef cattle diets with inactive dry yeast, a sugarcane by-product of ethanol distilleries and sugar mills
(Animal Feed Science and Technology, 2018)
Ammonium removal during laboratory culture of the Tehuelche Scallop Aequipecten tehuelchus
(National Shellfisheries Association, 2017-12)
Laboratory-scale research involving marine bivalves maintained in recirculating or closed aquaria requires control of seawater quality parameters. Among them, the total dissolved ammonium nitrogen (TAN), NH 4 + + ammonia ...
