The solubility of ammonium bicarbonate is smaller than that of other solid ammonia fertilizers, but it is more soluble in water. It is a physiologically neutral fast-acting nitrogen fertilizer, and it is the lowest nitrogen content in solid nitrogen fertilizer. Ammonium bicarbonate is a white compound which is in the form of granules, plate or columnar crystals. Since ammonium bicarbonate is a carbonate, it must not be placed with the acid because the acid reacts with ammonium bicarbonate to form carbon dioxide, which degrades the ammonium bicarbonate.
Ammonium bicarbonate application field
1. It is used as nitrogen fertilizer, suitable for all kinds of soils, and can provide ammonium nitrogen and carbon dioxide required for crop growth at the same time, but has low nitrogen content and easy to agglomerate;
2, used as analytical reagents, also used to synthesize ammonium salts and fabrics for degreasing;
3. Used as a chemical fertilizer;
4, can promote crop growth and photosynthesis, seedling long leaves, can be used for top dressing, can also be used as a base fertilizer for direct application, as a food starter, expansion agent;
5, as a chemical leavening agent, China regulations can be used for all kinds of foods that need to add a leavening agent, according to the production needs of the appropriate amount;
6, used as a food advanced fermentation agent. It can be used as a raw material for breading agents such as bread, biscuits and pancakes in combination with sodium bicarbonate, and is also used as a raw material for foamed powdered juice. Also used for blanching of green vegetables, bamboo shoots, etc., as well as medicines and reagents;
7. It can be used together with sodium bicarbonate as a raw material for a leavening agent such as bread, biscuits, and pancakes. The baking powder is also mainly composed of this product, with an acidic substance. It is also used as a raw material for foamed powdered juice. Green vegetables, bamboo shoots, etc. are used for blanching, 0.1% to 0.3%;
8, used as a fertilizer for farming.
Ammonium bicarbonate use precautions
1. It is not possible to mix ammonium bicarbonate with alkaline fertilizer to prevent ammonia from volatilizing and causing nitrogen loss.
2, to achieve "five do not apply": that is, do not mix fine soil, do not apply, there is dew does not apply, rain does not apply, no water in the field does not apply, the sun is not applied. If the fertilization time is sufficient, it is best to make the ammonium bicarbonate into a pellet or a deep fertilizer. In addition, in the transportation and storage, ammonium bicarbonate should be lightly loaded and unloaded, packed tightly, stored in a dry and cool place, and can not be mixed with alkaline fertilizer and human excrement to avoid loss of effective fertilizer.
3. Do not contact crop seeds, roots, stems or leaves during application to avoid burning plants.
4, it is not appropriate to do seed fertilizer, otherwise it may affect the seed germination.
5, bogey and mixed with bacteria and fertilizer: after the application of ammonium bicarbonate will release ammonia gas, contact with the bacterial fertilizer, will cause the living bacteria in the bacterial fertilizer to die, so that the bacterial fertilizer loses the effect.
6, avoid foliar spray: carbon ammonium leaf spray is easy to burn the foliage, affecting the photosynthesis of crop leaves.
