The second has some calcium in it and is a mixture of several chemicals including ammonium nitrate.
Calcium ammonium nitrate, often abbreviated CAN, is a fertilizer which is a blend (mixture) of about 20%-30% CaCO3 and 70%-80% Ammonium nitrate. It is used as a general plant fertilizer. It is an example for nitrogenous fertilizer.
Calcium ammonium nitrate (CAN) contains 27 % N and 20 % of ground limestone. Nitrogen is half in the nitrate form and half in the ammoniacal form. This results in rapid as well as permanent effect. The granulation of this fertilizer ensures a quick and exact dosing. Calcium ammonium nitrate has a form of 2 - 5 mm large of whitish till light brown colour granules. The fertilizer has excellent physico-mechanical properties and properties for storage
The chemical compound ammonium nitrate, the nitrate of ammonia with the chemical formula NH4NO3, is a white crystalline solid at room temperature and standard pressure. It is commonly used in agriculture as a high-nitrogen fertilizer, and it has also been used as an oxidizing agent in explosives, including improvised explosive devices. It is the main component of ANFO, a very popular explosive. It is used in instant cold packs, as hydrating the salt is an endothermic process.
