    en.wikipedia.org/wiki/Labeling_of_fertilizer

    In the U.K., fertilizer labeling regulations allow for reporting the elemental mass fractions of phosphorus and potassium.The regulations stipulate that this should be done in parentheses after the standard N-P-K values, as in "15-30-15 (15-13-13)".

  4. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Liquid ammonia has a very high standard enthalpy change of vapourization (23.5 kJ/mol; [28] for comparison, water's is 40.65 kJ/mol, methane 8.19 kJ/mol and phosphine 14.6 kJ/mol) and can be transported in pressurized or refrigerated vessels; however, at standard temperature and pressure liquid anhydrous ammonia will vaporize.

  5. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    Ammonia solutions decrease in density as the concentration of dissolved ammonia increases. At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml; it contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol/L.

    Micronutrients are consumed in smaller quantities and are present in plant tissue on the order of parts-per-million (ppm), ranging from 0.15 to 400 ppm or less than 0.04% dry matter. [ 32 ] [ 33 ] These elements are often required for enzymes essential to the plant's metabolism.

    en.wikipedia.org/wiki/Ammonia_pollution

    Production plants may release ammonia as a byproduct through chemical combustion or in effluent streams. [8] < 2% Anthropogenic Other Human waste, wild animal waste, wastewater, and decomposition all contribute to ammonia emissions via volatilization. [8] [16] < 1% Anthropogenic and natural

  9. Ammonia production - Wikipedia

    en.wikipedia.org/wiki/Ammonia_production

    Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [24] [25] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
