Potato growth, nitrogen balance, quality, and productivity response to water-nitrogen regulation in a cold and arid environment

open access: yesFrontiers in Plant Science
BackgroundThe pervasively imprudent practices of irrigation and nitrogen (N) application within Oasis Cool Irrigation zones have led to significant soil nitrogen loss and a marked decrease in water and nitrogen use efficiency.MethodsTo address this ...

Designing a Sustainable Temporary Grassland System by Monitoring Nitrogen Use Efficiency

open access: yesAgronomy, 2020
Assessing the efficiency of nitrogen application is a valuable first step in establishing an optimum N fertilizer management plan. The aim of this study was to elaborate a sustainable N management system for sown grassland installed in temperate regions,

Perennial Forage Trial Dr. Heather [PDF]

open access: yes, 2015
In 2015, the University of Vermont Extension Northwest Crops and Soils Program initiated a trial investigating forage yield, quality, and nitrogen use efficiency of cool season perennial grasses alone and in combination with red clover. The grass species

The Dual Origin Of The Nitrogen Deficiency In Comets: Selective Volatile Trapping In The Nebula And Postaccretion Radiogenic Heating [PDF]

open access: yes, 2012
We propose a scenario that explains the apparent nitrogen deficiency in comets in away that is consistent with the fact that the surfaces of Pluto and Triton are dominated by nitrogen-rich ice.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Effect of biochar and nitrogen management on nitrous oxide emissions in the Brazilian savanna (cerrado). [PDF]

open access: yes, 2012
The increase in nitrogen prices and demand for sustainable production gave importance to studies on strategies that increase nitrogen use efficiency. Two experiments were conducted aiming to test the effect of Eucalyptus sp charcoal on nitrous oxide (N2O)
