Hydrated calcium nitrate, also called Norgessalpeter (Norwegian salpeter), is mainly used as a component in fertilizers, but it has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns .
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
CF Industries Holdings, Inc. is an American manufacturer and distributor of agricultural fertilizers, including ammonia, urea, and ammonium nitrate products. The company is based in Northbrook, Illinois, a suburb of Chicago, [3] and was founded in 1946 as the Central Farmers Fertilizer Company.
Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO 3 or dolomite (Ca,Mg)CO 3 and 70-80% ammonium nitrate with 24-28 % nitrogen. Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007). [28] The main straight phosphate fertilizers are the superphosphates:
The calcium nitrate mentioned before, can as said be worked up as calcium nitrate fertilizer but often it is converted into ammonium nitrate and calcium carbonate using carbon dioxide and ammonia. Ca ( NO 3 ) 2 + 2 NH 3 + CO 2 + H 2 O 2 NH 4 NO 3 + CaCO 3 {\displaystyle {\ce {Ca(NO3)2 + 2 NH3 + CO2 + H2O -> 2 NH4NO3 + CaCO3}}}
Controlled release fertilizers are traditional fertilizers encapsulated in a shell that degrades at a specified rate. Sulfur is a typical encapsulation material. Other coated products use thermoplastics (and sometimes ethylene-vinyl acetate and surfactants, etc.) to produce diffusion-controlled release of urea or other fertilizers.
The Mosaic Company was formed in October 2004 by a merger between IMC Global, a fertilizer company formed in 1909, and Cargill's crop nutrition division. It is a combined producer and marketer of concentrated phosphate and potash with a customer base which includes wholesalers, retail dealers and individual growers worldwide.
Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The additional numbers are similarly reported in the oxide mass fraction form. For example, a Polish fertilizer labeled "NPK (Ca,S) 4-12-12 (14-29)" has an equivalent of 14% soluble calcium oxide and 29% total sulfur trioxide. [6]
