  2. Labeling of fertilizer - Wikipedia

    en.wikipedia.org/wiki/Labeling_of_fertilizer

    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]

  3. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. [1]

  4. Ammonium dihydrogen phosphate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_dihydrogen_phosphate

    The largest use of monoammonium phosphate by weight is in agriculture, as an ingredient of fertilizers. It supplies soil with the elements nitrogen and phosphorus in a form usable by plants. Its NPK label is 12-61-0 (12-27-0), meaning that it contains 12% by weight of elemental nitrogen and (nominally) 61% of phosphorus pentoxide P 2 O

  5. Potassium oxide - Wikipedia

    en.wikipedia.org/wiki/Potassium_oxide

    The chemical formula K 2 O (or simply 'K') is used in several industrial contexts: the N-P-K numbers for fertilizers, in cement formulas, and in glassmaking formulas. Potassium oxide is often not used directly in these products, but the amount of potassium is reported in terms of the K 2 O equivalent for whatever type of potash was used, such ...

  7. List of ammonium nitrate incidents and disasters - Wikipedia

    en.wikipedia.org/wiki/List_of_ammonium_nitrate...

    The NPK fertilizer cargo of the ship Ostedijk sustained a self-sustained decomposition (SSD) fire for 11 days. The ship carried a total of 6012 tonnes of NPK. Cargo hold 2, where the decomposition occurred, contained 2627 tonnes of fertilizer. NPK fertilizer contains about 15% ammonium nitrate.

  8. Calcium nitrate - Wikipedia

    en.wikipedia.org/wiki/Calcium_nitrate

    The fertilizer grade (15.5-0-0 + 19% Ca) is popular in the greenhouse and hydroponics trades; it contains ammonium nitrate and water, as the "double salt" 5Ca(NO 3) 2 ·NH 4 NO 3 ·10H 2 O. This is called calcium ammonium nitrate and often the name calcium nitrate prill is used as it always comes in a prilled (granular) form.

  9. Prill - Wikipedia

    en.wikipedia.org/wiki/Prill

    Fertilizers (ammonium nitrate, urea, NPK fertilizer) and some detergent powders are commonly manufactured as prills. [3] However prilling of ammonium nitrate and urea has in recent years been replaced by fluid bed granulation as this gives strong and more abrasion -resistant granules.
