Nitrogen Hotspots on the Farm—A Practice-Oriented Approach
Agronomy, 2022 The proactive management of nitrogen (N) on a farm is the best way to protect the environment against N pollution. The farm is the basic business unit, where simple and low-cost methods of identifying and ameliorating weaknesses (nitrogen hotspots) in ...

EFFECT OF MICROBIOLOGICAL TREATMENT ON THE NUTRITIVE VALUE OF CORN SILAGE [PDF]
Arab Universities Journal of Agricultural Sciences, 2016 The current study aimed to investigate the effect of microbiological treatment on improving the nutritive value of corn silage as animal feed. Dried whole corn plants were prepared and two ground silos (0.5 ton each) wereused for ensiling whole corn ...

Ab initio Screening of a Sulfur Desorbed MoS$_2$ Photocatalyst for Nitrogen Fixation [PDF]
arXiv, 2017 The following study investigates the thermodynamic reaction barriers during nitrogen fixation for an inorganic sulfur desorbed photocatalyst Molybdenum disulfide surface. The design space is investigated using an density functional theory (DFT) method within a space bound by MMoS$_2$ M=Mo,Fe,Co.

Interaction of ammonium with birnessite: Evidence of a chemical and structural transformation in alkaline aqueous medium [PDF]
arXiv, 2022 The ammonium cation interaction with Na-birnessite in aqueous alkaline medium was studied. Solution and solid analysis give evidence that birnessite is not only acting as a cationic exchanger toward NH4+. The surface analysis performed by XPS showed that N1s spectra are characterized by the existence of two different environments: one assignable to an ...

Analysis of Photocatalytic Nitrogen Fixation on Rutile TiO$_2$(110) [PDF]
arXiv, 2017 Photocatalytic nitrogen fixation provides a promising route to produce reactive nitrogen compounds at benign conditions. Titania has been reported as an active photocatalyst for reduction of dinitrogen to ammonia; however there is little fundamental understanding of how this process occurs. In this work the rutile (110) model surface is hypothesized to
