“…With respect to studied factors separately, data shown in Table (4) revealed that wheat and peanut yield components (straw, grains and seeds) of both studied crops were significantly stimulated due to applied both nitrogen fertilizers sources encapsulated with polymer as compared to control treatments; this may be due to caking occuring in case of coated ammonium nitrate due to Van der Waals force, which are electrostatic and moisture bonding forces when particles come into contact. The deviation of particle shape from round or spherical increased the area of particle contact and thereby increased caking (Lotspeich and Petr ,2014). Furthermore, coated urea was more effective as compared to ammonium nitrate for increasing the yield components at both studied seasons, probably due to high solubility of ammonium nitrate fertilizers that increase concentration of soluble salts in the root zone and osmotic stress, specific injuries to plant at different growth stages thus decreasing yield (Fenn and Hossner, 1985) and (Hassan et al 2010).…”

A field experiment was carried out at El-Ismailia Agriculture Research Station farm, Agric. Res. Center (ARC), Egypt during two successive seasons (2015/2016). The institute farm is located at 30o 35' 41.9" N latitude and 32o 16' 45.8" E longitude. Wheat plants (Triticum aestivum L., CV. Giza 168) was planted during winter season (2015) and peanut plants (Arachis hypogaea) was planted during summer season (2016) in a sandy soil under sprinkler irrigation system, to improve the soil chemical properties, eliminate or reduce labor intensive of fertilizers losses, as well as increase in apparent nutrient recovery, through improving the nutritional status, minimize nitrogen loss, maintaining growth and yield of both wheat and peanut crops. Two sources of nitrogen fertilization were used, urea and ammonium nitrate with two rates (75% and 100% from the recommended dose) along with four rates of polymer (Hydrogel 0%, Hydrogel 1%, Hydrogel 2%, Hydrogel 3%) as a coating film material. Moreover, samples of the same nitrogen fertilizers were coated with the same four rates of polymers to be then incubated under laboratory condition to study the cumulative released percentage versus time, from both N-sources, along with the different rates of polymers; finally a field experiment was conducted. With regard to incubation experiment, results indicated that, the release of nitrogen from uncoated N-sources showed rapid and highly increase during the first two hours; the increase reached 94.35 % and 98.36% for both urea and ammonium nitrate respectively, uncoated urea being more responded as compared to uncoated ammonium nitrate. Generally, presence of polymer, as a coating material, caused slow gradual increase for soluble nitrogen as time goes up to 15 days as compared to without polymer treatment.The calculation of swelling ratio of hydrogel estimated that every one gram of hydrogel was swollen by uptake of 500 ml of water, this means that every 1 gram coating material from the used polymer absorbed 500 gm from the water. Also, Field Emission Scanning Electron Microscope noted that, the coated urea was smaller diameter, denser, more uniform and much smoother surface as compared to ammonium nitrate. On the contrary, the cross section of the coating shell of ammonium nitrate had a larger diameter, rough surface with large cavities along with both open and closed porosity.With regard to field experiment, results revealed that, the pH values in the soil after harvesting were significantly affected by both coated N-sources, as compared to uncoated treatments, for both tested crops; pH values increased significantly with time in presence of urea as compared to ammonium nitrate. Moreover, increasing the rate of nitrogen fertilization along with increasing the rate of applied polymer caused a significant increase in EC values during both tested seasons. Values representing nitrogen and potassium availability in soil, total contents (straw and grains or seeds) and yield components for both tested crops increased significantly in both co...

“…The morphology of the ammonium nitrate has been studied by [6][7][8][9][10][11][12][13]. Biessikirski et al reported that the surface of ammonium nitrate porous prill (AN-PP) was highly deformed and was characterized by the presence of numerous wrinkles, which influenced the absorption index [6].…”

“…Moreover, they presented the formation of the prill surface during the heating process. Lotspeich and Petr reported that fertilizer based ammonium nitrate (AN-F) possessed pumice-like surface [8]. In turn, in the cross-section of whole AN-PP prill, the presence of wrinkles was found [8].…”

Ammonium nitrate fuel oil (ANFO) samples based on fertilizer (AN-F) and ammonium nitrate porous prill (AN-PP) were studied. Tests were carried out using both a thermogravimetric analyzer and differential scanning calorimetry (TGA/DSC). Furthermore, the scanning electron microscopy analysis (SEM) of ammonium nitrate(V) (AN) concerning either their surface or cross-section was performed. Based on the SEM results, it was shown that the surface of AN-F grains was flat and slightly deformed, while the AN-PP surface was wrinkled and deformed. Furthermore, the various steps of thermogravimetric process exhibited continuous AN phase transition according to precise temperatures. From TGA analysis, a significant mass loss was found as a result of ANFO decomposition. Direct comparison of SEM and TGA/DCS data led to the conclusion that ANFO based on AN-F was characterized by lower absorption of FO in contrast to AN-PP.

The aim of the present study is to limit the detonation properties of ammonimum nitrate fertilizers used in agriculture. The results presented in this paper are obtained by using analytical methods. This study also evaluated the physiochemical properties of nitrogenous fertilizers such as the specific heat, explosive enthalpy, and the effects of dolomite and fly ash additives that have been suggested for increasing the nutritional content of ammonium nitrate fertilizers. The results obtained regarding additives differ from those of previous studies. The present study produced important results regarding additives, and efforts were made to limit certain physical properties such as the detonation enthalpy and detonation velocity. KEYWORDS
