Magnesium is nitric acid, those (China)

Magnesium nitrate Mg (NO3) 2 - colorless hygroscopic crystals with a cubic lattice.

Let's also dissolve in ethanol, methanol, liquid NH3. Nona, hexa and dihydrates crystallize from aqueous solutions, depending on the concentration.

A component of complex fertilizers, since magnesium is part of chlorophyll, which is necessary for photosynthesis, promotes an increase in the activity of many enzymes and acts as a phosphorus transporter ... High solubility and low electrical conductivity make the product extremely suitable for foliar feeding and fertigation, especially when using irrigation water with a high concentration of salts.

Fertilizer is used for root and foliar nutrition of vegetables, berries, fruit crops, grapes; oxidizer in pyrotechnic compositions.
