The ammonium nitrate is the most valuable and popular granulated fertilizer. The addition of magnesium stimulates improvement in the plants' condition, prevents instances of magnesium lack, and improves the nutritive value of the crops. The ammonium nitrate enriched with magnesium is a universal nitrogen-based fertilizer. It can be applied to all plants and to all soil types. Magnesium intake is not exceeded, even when large quantities of the fertilizer are used. Magnesium deficiency in the soil causes an inhibition in the plants' starch and sugar production process. Winter crops are then easily frozen.
