ammonium nitrate fertilizer properties

♦ Dense black smoke from fertilizer storage is an indication that significant amounts of combustible materials are involved in the fire and the risk of explosion is increased. Ammonium nitrate is a colourless crystalline substance (melting point 169.6 °C [337.3 °F]). A number of enterprise equipment shutdown, ammonium nitrate supply and demand tension to a substantial increase in price, How to extract calcium ammonium nitrate ammonium nitrate, The high sulfur coal mine using ammonium nitrate explosives. The reaction is violent owing to its highly exothermic nature. Prepared by Douglas B. Beegle, Extension Agronomist. This is called the oxide form for elemental phosphorus (P), and potassium (K). 222 Shenzhen Road, Qingdao,P.R CHINA, Address : Jln. Means that work by cutting off the air supply to the fire (eg foam, dust, sand) are not effective. 0000005695 00000 n In several of these facilities, a lack of knowledge of the dangers and the absence of adequaete means of firefighting and fire detection has been observed. This publication is available in alternative media on startxref A given weight of two fertilizers can contain different amounts of actual plant food. /Filter /FlateDecode When expansion occurs during application to the soil, it immediately becomes a gas. 72 0 obj However, if the heat released by the decomposition itself is sufficient, the process enter a self-sustaining state. Both the β-rhombic to α-rhombic forms are potentially present at ambient temperature in many parts of the world but have a 3.6% difference in density. Properties: UNIDO and International Fertilizer Development Center (1998), This page was last edited on 23 November 2020, at 02:59. So you can't use the hammer, broken caking of ammonium nitrate with sticks, which can be modified, so that the granular or adding stabilizer and inert material, in order to reduce the moisture absorption and increase security. Most popular articles in the previous month, Ammonium nitrate: properties, applications, hazards, Accidents and incidents with ammonium nitrate, Pollution: new European register gives public access to information on emissions from European industrial facilities, Agent Orange: Its effects in the Vietnam War and After, Hard Water and Scale Cost Companies Billions of Dollars, Heart of Darkness: the Tragedy of the Congo, 1960-67, The OSS and Project SAFEHAVEN: Tracking Nazi Gold. The fertilizer law in Pennsylvania specifies certain solubility criteria that must be met by a fertilizer nutrient in order for that nutrient to be included on the fertilizer label. @H�4tsĕpF�U�|�+ Phosphorus must be dissolved in water to be taken up by plants. Many of these materials greatly, but temporarily, increase the soil pH. Both decomposition reactions are exothermic and their products are gas. While there is no standard for particle size, most fertilizers are sized to pass through a No. An explosive charge within or in contact with a mass of ammonium nitrate causes the ammonium nitrate to detonate. Application rates must be determined on the basis of the plant food needed. Most fluids weigh between 10 and 12 pounds per gallon. Explosives: Ammonium nitrate alone is not an explosive. At this economic optimum, the value of any yield increase produced by higher fertilizer rates just covers the cost of the additional fertilizer. 0000004947 00000 n 0000001772 00000 n Coronavirus/COVID-19: Update for Event Attendees. 3v��Q�ߓ� ��IT�n�����]WН�ھ(hJ��oV�V���y�v��;@������hQ�$��vf�Q�2��K�aDVi�=��t5Srk����,Ӟ�ٛ3p,���$��D���Z��g�/_�#m�!��-^���D>?��ʼn�%/`]��ԝA �����h�[޵�uE�J �6)�+Kƕ܊�C�W���Do��chy-p�_QL��� `��*X)���1�R�-�>�)h�jك�o{�� ��w�眫�N _{���ש�=#Yy��&S�����Ӧe�״! Examples include the Oppau explosion of 1921 (one of the largest artificial non-nuclear explosions), the Texas City disaster of 1947, the 2015 Tianjin explosions in China, and the 2020 Beirut explosion.[37]. Many ammonium nitrate disasters, with loss of lives, have occurred. It is included in the Chemical Family of Nitrogen Fertilizer Solution. In case of fire, or decomposition in a pile of bulk fertilizer, the use of metal, telescopic fire hoses (victor lances) that penetrate into the pile is particularly effective. Suspension fertilizers are fluids in which solubility of the components has been exceeded and clay has been added to keep the very fine, undissolved, fertilizer particles from settling out. by overpressure or impact shock on ​​the mass of decomposing material, which has undergone partial melting and has been contaminated by other substances (chemical explosion). Ammonium nitrate can absorb enough moisture to liquefy. Materials of different sizes tend to segregate as the fertilizer is handled and spread. ��!F�+��&��E��������P�����Z�����Lg2����>�/r�u4��3�Y�|�J���/]v�D�$�qE"�8�%M`��!� � �aQ�{i�Y�� AN�7զ��i���d,Ix[�e�9MW�ؚ]�g�ϼK�un�ִ�����Pv���]sZrν�B�HSPJ0��?-� The common potassium materials are neutral salts that have no effect on the soil pH. It is industrially produced using ammonia and nitric acid. For example, 100 pounds of a 10-30-10 fertilizer contains 10 pounds of N, 30 pounds of P2O5, and 10 pounds of K2O, whereas 100 pounds of a 7-21-7 fertilizer contains 7 pounds of N, 21 pounds of P2O5, and 7 pounds of K2O. 0000005586 00000 n endstream endobj 63 0 obj <> endobj 64 0 obj <> endobj 65 0 obj <>>>>> endobj 66 0 obj <> endobj 67 0 obj <> endobj 68 0 obj <>/Font<>/ProcSet[/PDF/Text]>> endobj 69 0 obj <> endobj 70 0 obj <> endobj 71 0 obj [/CalRGB<>] endobj 72 0 obj <> endobj 73 0 obj <>stream It easily explodes under the action of calefaction or detonation agent. At present, the production of ammonium nitrate is a white powder crystal, the other is white or light yellow particles. These prills or granules are the typical AN products in commerce. Chemical Advisory: Safe Storage, Handling, and Management of Ammonium Nitrate, United States Environmental Protection Agency, "Report for Kooragang Island Update PHA MOD1 Report", "Guidance for Compatibility of Fertilizer Blending Materials", "Material Safety Data Sheet, Ammonium nitrate MSDS", "Lebanon's president calls for two-week state of emergency in Beirut after blast", https://en.wikipedia.org/w/index.php?title=Ammonium_nitrate&oldid=990155014, Short description is different from Wikidata, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, All articles with vague or ambiguous time, Creative Commons Attribution-ShareAlike License, Shock-to-detonation transition. Its main commercial use is as a fertilizer with high nitrogen content. 0000005268 00000 n but virtually 100% of the chemical now used is synthetic. Any gas released in the event of a fire in a fertilizers production or storage area, should be treated as toxic and should therefore be approached using a respirator (SCBA) with a face mask under positive pressure. Otherwise, it can coalesce into a large, solid mass. �i�q�+(M[̙�ˋ��]����i ��� ��_���Q�d���Ȉ�f H�A�>fS#���/
