This is the mechanical mixture of ammonium nitrate and limestone (dolomite). This is a pelletized substance containing the following useful elements: nitrogen (26-28%), nitrogen in the nitrate form (14%), calcium and magnesium oxides (4 and 2%). Flowability is 100%. In comparison with ammonium nitrate, calcium carbonate-ammonium nitrate features better physical and chemical properties. It is less hygroscopical and can be easily added to soil by mechanical means. It is a flammable substance.
