[4] In Australia, macronutrient fertilizers are labeled with an "N-P-K-S" system, which uses elemental mass fractions rather than the standard N-P-K values and includes the amount of sulfur (S) contained in the fertilizer. [5] Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount ...
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}}}
UAN is a solution of urea and ammonium nitrate in water used as a fertilizer.The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers.
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.
Phosphate rich organic manure is a type of fertilizer used as an alternative to diammonium phosphate and single super phosphate.. Phosphorus is required by all plants but is limited in soil, creating a problem in agriculture In many areas phosphorus must be added to soil for the extensive plant growth that is desired for crop production.

Urea phosphate is a 1:1 combination of urea and phosphoric acid that is used as a fertilizer. It has an NPK formula of 17-44-0, [ 1 ] and is soluble in water, producing a strongly acidic solution. Urea phosphate is available in fertilizer vendor bags that carry a UP signet on the packaging.
