Ammonium nitrate
Ammonium nitrate is a highly effective nitrogen mineral fertilizer in granular form containing nitrogen in both ammonium and nitrate forms.

This fertilizer serves as a universal source of nutrition that stimulates intensive growth of the vegetative mass of crops. Due to the presence of two nitrogen forms, the plant receives nutrients both immediately after application and over a more extended period.
It is primarily used in spring as a base fertilizer during seedbed preparation or for early top-dressing of winter and spring crops. It is crucial to apply ammonium nitrate to moist soil, as water is required for the granules to dissolve and for the nitrogen to be absorbed by the plant.
A common mistake is over-application, which leads to nitrate accumulation in produce and excessive vegetative growth at the expense of yield. It is also risky to leave the fertilizer on the soil surface in hot and dry weather without incorporation, as this causes nitrogen loss through ammonia volatilization.
