Aqua ammonia
NH3*H2O
Aqua ammonia is produced in two grades depending on the purpose:
Grade A - for the industry.
Grade B - in agriculture as a nitrogen fertilizer.
Application of this fertilizer for dressing cultivated crops is efficient. Use of ammonium hydroxide in agriculture allows reducing sharply the labor expenses due to the complete mechanization of the transportation process, storage and fertilization. Aqua ammonia is non-combustible and nonexplosive liquid.

|---|---|---|
| A | B | |
| Appearance | Transparent colorless liquid | Transparent colorless liquid; yellow color is allowed |
| Mass fraction of ammonia, %, no less than | 25 | 25 |
| Percentage by weight of fixed residue, g/dm3, no more than | 0.07 | not standardized |
| Percentage by weight of dioxide of carbon, g/dm3, no more than | not standardized | 8 |
Aqua ammonia is transported by railway, car and water transport in pressure-tight vehicles according to the transportation rules acting on the given type of transport.
The product of grade A is transported in rail tank cars and ammonia trucks. The product of grade B is transported in the tanks with the bottom discharge and ammonia trucks. At work with liquid ammonia one should use the individual means of skin and respiratory organs protection. The warranty period of storage is 3 months from the manufacturing date.

Urea
CO(NH2)2
Urea is the most concentrated solid nitrogen fertilizer referring to amide group. Two grades of urea are manufactured depending on the purposes: grade A (white crystals and granules) for industry, and B (white slightly coloured granules) for agriculture. It is well dissolved in water. Under good conditions of storage urea is weakly caked.
Urea is used for kinds of soil and for all types of agricultural crops as the main, presowing fertilizer and for top dressing. It is used for rice cultivation, foliar dressing of vegetable and fruit crops, and for late corn dressing in order to increase content of proteic substance in grain.
Differing from other kinds of fertilizers, even in case of increased concentration (>5%) urea does not burn leaves – and at the same time it is good absorbed by plants.
Urea of grade A is also used as the fodder additive for ruminants (according to forage value 100 g of the product correspond to 260 g of protein or 2.7 kg of oat).

Ammonium nitrate
NH4NO3
Ammonium nitrate is an ammoniac-nitrate fertilizer, high nitrogen content in which allows to gain rich harvest. It is manufactured as a prilled product and quickly absorbed by plants.
Ammonium nitrate is used for all kinds of soil and for all types of agricultural crops. In case of buffer non-acidic soils (pH > 6-7) it is possible to use ammonium nitrate on a regular basis, while at usage on acidic soils liming (adding of lime powder) is necessary.
Ammonium nitrate is used as a presowing fertilizer and for top dressing of winter cereals providing extra yield of 3-8 centners per hectare. It is effective joint application of ammonium nitrate with phosphate and potassium fertilizers.

Calcium Ammonium Nitrate (CAN)
NH4NO3*CaCO3*MgCO3
Calcium ammonium nitrate is a mixture (fuse) of ammonium nitrate and ground limestone. The product is physiologically neutral. It is manufactured in granular form (with size varied from 1 to 5 mm) and suitable for mixing with phosphate and potassium fertilizers. In comparison with ammonium nitrate CAN has better physical-chemical properties, less water-absorbing and caking as well as it can be stored in stacks.
Calcium ammonium nitrate can be used for all kinds of soil and for all types of agricultural crops as the main, presowing fertilizer and for top dressing. Under systematic use the fertilizer doesn’t acidify soil and supplies plants with calcium and magnesium. It is the most efficient in case of acidic and sodic soils and soils with light granulometric composition.
