Ammonium nitrate (AN) is a strong oxidizer that undergoes phase transitions and thermal decomposition at relatively low temperatures. This—as verified by historical facts—constitutes challenge for the fire department during rescue operations. AN also highly reactive material widely used production of, i.a., fertilizers explosives. The latter are popular not only in military applications but ind...

We compared the results of a long-term (65 years) experiment in a South African grassland with the world's longest-running ecological experiment, the Park Grass study at Rothamsted, U.K. The climate is warm and humid in South Africa and cool and temperate in England. The African grassland has been fertilized with two forms of nitrogen applied at four levels, phosphorus and lime in a crossed des...

nitrogen is the primary nutrient that shows deficiency in saline areas, therefore, proper nitrogen fertilizer management is one of the strategies to achieve higher wheat grain yield.  a field experiments in a saline soil was performed on wheat with a factorial arrangement in randomized complete block design with four replications, in rostagh area, 25 km from yazd. the first factor was nitrogen ...

For the granulation of nitrate-sulfate-carbonate melt, prilling method is applied using a tower. The composition and properties new types fertilizers were studied. It shown that with ratio NH 4 NO 3 : СаСО (NH ) 2 SO = 100: 24: 1 product contains 28,03% - N, 0,50% , 10% СаО has granule strength 6.03 MPa, which much higher than pure granules (1.32 MPa). absorption AN 4.82 g. With an increase in ...

Controlledrelease fertilizers (CRFs) offer an excellent option to improve nutrients uptake by plants and reduce the environmental hazards due to excess release of chemicals. Polymer-coated fertilizers, compared to the other types of CRF, are by far the most intensively researched topic because of their great characteristics. Polymercoated fertilizers, which are less sensitive to the soil and en...

The aim of the study is to determine chemical and physical properties gallstones Antalya province. In line with this, mineralogical characteristics 1243 gallstone samples from 69 patients were analyzed, using scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FTIR) analysis. 
 Cholesterol, carbonate apatite, calcium carbonate, phosphate bilirubinate, protein conten...

The link between anthropogenic emissions of carbon dioxide, increasing atmospheric CO2 levels, and concomitantly increasing global temperatures is established and accepted. The use of aqueous ammonia, to capture CO2 and produce an inexpensive nitrogen fertilizer, ammonium bicarbonate (ABC), is believed to be a feasible approach to CO2 sequestration. Due to the varying concentrations of reactant...

Abstract A recently proposed combination of headspace liquid-phase microextraction with an optical immersion probe (HS-LPME-OIP) was adapted for the spectrophotometric determination ammonium. The developed method is based on conversion ammonium ions to ammonia in a 0.15 M sodium hydroxide solution, followed by absorption 200 µL Nessler's reagent solution preliminary diluted distilled water (1:1...
