2. Ammonium sulfate - Wikipedia

   en.wikipedia.org/wiki/Ammonium_sulfate

   Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C.

3. Fertilizer - Wikipedia

   en.wikipedia.org/wiki/Fertilizer

   Liquid fertilizers comprise anhydrous ammonia, aqueous solutions of ammonia, aqueous solutions of ammonium nitrate or urea. These concentrated products may be diluted with water to form a concentrated liquid fertilizer (e.g., UAN). Advantages of liquid fertilizer are its more rapid effect and easier coverage. [24]

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. Ammonium nitrate - Wikipedia

   en.wikipedia.org/wiki/Ammonium_nitrate

   Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.

6. Victor A. Tiedjens - Wikipedia

   Tiedjens also experimented with different methods of fertilizing crops. He discovered plants can absorb fertilizer nutrients only when they are in a liquid form. [4] [5] He rationalized that if he dissolved dry materials in water they would be better utilized by the plant. This led to the inception of liquid fertilizers.

7. 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 ...
