Radium chloride is an inorganic compound with the chemical formula Ra Cl 2. It is a radium salt of hydrogen chloride. It was the first radium compound isolated in a pure state. Marie Curie and André-Louis Debierne used it in their original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a ...
Additionally, radium phosphate, radium oxalate, and radium sulfite are probably also insoluble, as they coprecipitate with the corresponding insoluble barium salts. [5] The great insolubility of radium sulfate (at 20 °C, only 2.1 mg will dissolve in 1 kg of water) means that it is one of the less biologically dangerous radium compounds. [ 6 ]
The use of inorganic selenium fertilizers can increase selenium concentrations in edible crops and animal diets thereby improving animal health. [31] It is useful to apply a high phosphorus content fertilizer, such as bone meal, to perennials to help with successful root formation. [6]
The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition.

Inorganic fertilizer use by region [23] Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients.
