Ammonia saltpeter, Sumy region.

Ammonium nitrate (NH4NO3, other names - ammonium nitrate, ammonium nitrate, ammonium salt of nitric acid). The main active ingredient is nitrogen. Ego is contained in the composition of the fertilizer from 26% (low grades) to 34.4% (higher grades). The second macroelement of classic ammonium nitrate is sulfur, which is contained in the composition of this agrochemical from 3 to 14%. Ammonium nitrate, along withurea (urea) is an ideal top dressing for spring use. At the start of their development, plants do not hesitate to use nitrogen in huge doses, and in tandem with sulfur, this element is especially good and quickly absorbed. This property explains its presence in the composition of agrochemicals, because sulfur by itself is not the most nutritious substance for plant organisms. Physiologically, this is an acidic fertilizer, which, at the same time, does not acidify the soil with a normal pH reaction. But if ammonium nitrate is used on acidic soils, calcium carbonate should be added in parallel, in the proportion of 0.75 g per 1 g of saltpeter. Ammonium nitrate is needed, first of all, for active saturation of plants with nitrogen. This is its main task, the macro- and microelements additionally included in the composition help to solve it.
