Description

Magnesium nitrate contains magnesium MgO15.7%, nitrogen N10.9%. Nitrogen is contained in nitrate form, which contributes to a better absorption of magnesium by plants. Magnesium is a part of chlorophyll, which is necessary for photosynthesis, promotes the activity of many enzymes and acts as a phosphorus carrier. High solubility and low electrical conductivity make the product extremely suitable for foliar and root top dressing, especially when using irrigation water with a high concentration of salts
Inorganic compound magnesium nitrate is widely used in the agricultural industry. This salt remains one of the most common fertilizers, due to its versatility, efficiency and safety. In particular, magnesium nitrate can be used on any soil, does not cause burns of the aboveground part of plants and is compatible with other microfertilizers.

 

Properties

p> Magnesium nitrate is a colorless hygroscopic crystal with a cubic lattice. Chemical formula Mg (NO3) 2 Activity index of hydrogen ions, (pH) 5.5-6.5 Mass fraction of magnesium (MgO),% 15.7 Mass fraction of nitrogen (NO3),% 10.9 Melting point 426 ° C. The melting point is 426 ° C. At a temperature of 300 ° C, decomposition into magnesium oxide (MgO) and nitrogen oxides begins.
Solubility in 100 g / water: 73.3 g at 20 ° C, 81.2 g at 40 ° C, 91.9 g at 60 ° C. Magnesium nitrate is soluble in ethanol, methanol and liquid ammonia. From aqueous solutions, depending on the concentration, nona-, hexa- and dihydrates of magnesium nitrate are formed.

Receiving

Anhydrous magnesium nitrate is obtained by the interaction of magnesium with a tetraoxide (N2O4). Hexahydrate is obtained by synthesis of magnesium oxide of special purity and nitrates of other metals.

In industry, nitromagnesite is derived from a natural mineral. In the laboratory, magnesium, magnesium oxide or magnesium hydroxide with dilute nitric acid is obtained by reacting.

 

Application

Magnesium nitrate is a component of complex fertilizers, since magnesium is part of chlorophyll, which is necessary for photosynthesis, promotes the activity of many enzymes and acts as a phosphorus carrier. High solubility and low electrical conductivity make the product exceptionally suitable for foliar top dressing and fertigation, especially when using irrigation water with a high concentration of salts. Fertilizer is used for root and non-root nutrition of vegetable, berry, fruit crops, grapes; oxidizer in pyrotechnic compositions. The use of magnesium nitrate as fertilizer in crystalline or granular forms, despite the content of two nutritional components in water-soluble form - actually magnesium and nitrogen (in the form of nitrate ion), and high agrochemical efficiency, is substantially limited by the considerable hygroscopicity of the product and increased propensity to caking during storage and transportation.

Safety requirements

Precautions when applying magnesium nitrate to the soil and / or preparing an irrigation solution are standard. It is recommended to use protective equipment for skin, mucous membranes, eyes and do not allow chemicals to enter the body.
