Ammonium nitrate (AN) is commonly used as a fertilizer and is the fundamental ingredient of industrial explosives [1]. It has been observed that one of the most important factors that affect explosive performance of ammonium nitrate and fuel oil is the prills volume of porosity. The large amount of porosity identified in explosive grade AN prills allows for an absorption rate between 12 and 16 ...

Biobased nitrogen (N) fertilizers derived from animal manure can substitute synthetic mineral N fertilizer and contribute to more sustainable agriculture. Practitioners need obtain a reliable estimation of the biobased fertilizers’ value. This study compared estimates for pig slurry (PS) liquid fraction digestate (LFD) using laboratory incubation plant-growing experiments. A no-N treatment was ...

Ammonium nitrate (AN) is produced by the reaction of ammonia and nitric acid, and a waste condensate is obtained. The condensate contains pure AN in concentration up to 10g/L. The salt content in the condensate is too high to discharge immediately into the river thus it must be treated. This study is concerned with the treatment of condensates from an industrial AN production by combination of ...

At 7:51 p.m. on 17 April 2013, an explosion rocked the town of West, Texas, when fertilizer-grade ammonium nitrate stored at the West Fertilizer Company blew up with the explosive force of 12.5 tons of TNT. Fifteen people died, and 260 were injured. More than 150 offsite buildings were destroyed by the blast and subsequent fire, among them a middle school, a high school, a nursing home, and an ...

Most of the nutrients in wastewater come from human urine and their recycling for agricultural purposes is very limited. After source separation, can be treated to produce various urine-based fertilizers. This study aims characterize nitrogen use efficiency different Nine fertilizers were compared together with ammonium nitrate cattle slurry a greenhouse pot trial English rye-grass, (Lolium per...

A nitrogen (N) source comparison study was conducted to further evaluate the effects of inorganic N source and placement on growing-season and non-crop period soil nitrous oxide (NO). Commercially available controlled-release N fertilizers were evaluated for their potential to reduce NO emissions from a clay loam soil compared with conventionally used granular urea and urea-ammonium nitrate (UA...

Nitrous oxide (N2O) is an important greenhouse gas and a primary cause of stratospheric ozone destruction. Despite its importance, there remain missing sources in the N2O budget. Here we report the formation of atmospheric nitrous oxide from the decomposition of ammonium nitrate via an abiotic mechanism that is favorable in the presence of light, relative humidity and a surface. This source of ...

Bolivia and Chile. These diverse countries hold not only striking beauty throughout these regions, but also vast natural resources. In the Atacama Desert region, the discovery of such important natural resources have left residual problems lingering in the economic and political relations between these South American nations, and still cause tensions today. This paper explores historic disputes...

Embryonic mortality in many aquatic animals, including most amphibian species, is usually very high. In addition to mechanical and chemical defences, some species have developed behavioural patterns that can increase egg survival. For example, females of some newt species protect their eggs by wrapping them in leaves of aquatic plants. We have studied the effects of ammonium nitrate (nominal co...
