   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 most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate , 35% urea and only 20% water.

4. Phosphate rich organic manure - Wikipedia

   en.wikipedia.org/wiki/Phosphate_rich_organic_manure

   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.

5. Controlled-release fertiliser - Wikipedia

   en.wikipedia.org/wiki/Controlled-release_fertiliser

   Controlled release fertilizers are traditional fertilizers encapsulated in a shell that degrades at a specified rate. Sulfur is a typical encapsulation material. Other coated products use thermoplastics (and sometimes ethylene-vinyl acetate and surfactants, etc.) to produce diffusion-controlled release of urea or other fertilizers. "Reactive ...

   The radioactive content of the fertilizers varies considerably and depends both on their concentrations in the parent mineral and on the fertilizer production process. [ 94 ] [ 101 ] Uranium-238 concentrations can range from 7 to 100 pCi/g (picocuries per gram) in phosphate rock [ 102 ] and from 1 to 67 pCi/g in phosphate fertilizers.

   Soybean oil is the primary source of biodiesel in the United States, accounting for 80% of domestic biodiesel production. [184] Soybeans have also been used since 2001 as fermenting stock in the manufacture of a brand of vodka . [ 185 ]

8. Agricultural chemistry - Wikipedia

   en.wikipedia.org/wiki/Agricultural_chemistry

   Fertilizers are a major consideration. While organic fertilizers are time-honored, their use has largely been displaced by chemicals produced from mining (phosphate rock) and the Haber-Bosch process. The use of these materials dramatically increased the rate at which crops are produced, which is able to support the growing human population.
