The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
The early product had 60 percent of the total nitrogen cold-water-insoluble, and the unreacted (quick-release) less than 15%. Methylene ureas , e.g. methylene diurea , were commercialized in the 1960s and 1970s, having 25% and 60% of the nitrogen as cold-water-insoluble, and unreacted urea nitrogen in the range of 15% to 30%.
Miracle-Gro, a water-soluble fertilizer, was developed after Horace Hagedorn met nurseryman Otto Stern and learned of Stern's troubles shipping plants in 1944. [ 1][ 2][ 3] They hired O. Wesley Davidson, a Rutgers University professor, to develop the fertilizer. [ 1] In 1950, the company was formed after Hagedorn's wife Peggy named the product ...
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 ...
Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO 3− ), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats ...
NPK ratings consist of three numbers separated by dashes (e.g., 10-10-10 or 16-4-8) describing the chemical content of fertilizers. [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 ...
