Therefore, pure KCl is 39.09/(39.09 + 35.45) = 52% potassium and 48% chlorine by weight. Its K value is therefore 52/0.83 = 63; that is, a fertilizer that gets all its potassium from K 2 O and has the same potassium contents as pure KCl would have to be 63% K 2 O. Pure KCl fertilizer would thus be labeled 0-0-63.
[1] [2] [3] The schemes follows from the Insecticides Act of 1968 [1] and the Insecticides Rules of 1971. The labeling follows a general scheme as laid down in the Insecticides Rules, 1971, and contains information such as brand name, name of manufacturer, name of the antidote in case of accidental consumption etc. A major aspect of the label ...
[29] [30] The first number represents the percentage of nitrogen in the product; the second number, P 2 O 5; the third, K 2 O. Fertilizers do not actually contain P 2 O 5 or K 2 O, but the system is a conventional shorthand for the amount of the phosphorus (P) or potassium (K) in a fertilizer.
Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example, a 10-10-15 fertilizer has 10 percent nitrogen, 10 percent available phosphorus (P 2 O 5) and 15 percent water-soluble potassium (K 2 O). Sulfur is the fourth element that may ...

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.

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.
