How to choose and buy agricultural ammonium bicarbonate?

How to choose and buy agricultural ammonium bicarbonate? What do you need to pay attention to when buying agricultural ammonium bicarbonate? How to distinguish the authenticity of ammonium bicarbonate? Please introduce the method of agricultural ammonium bicarbonate is a sulfate-free nitrogen fertilizer, it releases both carbon dioxide and ammonium nitrogen, its elements are crop nutrients, in line with the crop absorption mechanism, is an ideal substance for crops to synthesize amino acids. In terms of the nutritional function of fertilizer, ammonium bicarbonate is all directly absorbed fertilizer, it does not contain intermediate products and final decomposition products, long-term application does not affect the soil quality. Ammonium bicarbonate is cheap and can be used as topdressing in most crops. the following introduces the selection and purchase method of agricultural ammonium bicarbonate for reference: a look: the ammonium bicarbonate obtained by ammonia absorbing carbon dioxide is translucent crystalline, while the "granular ammonium bicarbonate" produced by filling excipients is opaque and white. The second smell: the ammonium bicarbonate for agriculture obtained by absorbing carbon dioxide by ammonia has a strong irritating "ammonia" taste, while the "ammonia" taste of "granular ammonium bicarbonate" produced by filling and adding auxiliary materials is much smaller, and the more auxiliary materials are added, the less obvious the "ammonia" taste is. Three kneading: the agricultural ammonium bicarbonate obtained by absorbing carbon dioxide with ammonia water feels like "sand" when it is kneaded by hand, while the "granular ammonium bicarbonate" produced by filling and granulation feels hard and not easy to crush. Fourth solution: prepare a cup of warm water for experiment. the agricultural ammonium bicarbonate obtained by absorbing carbon dioxide by ammonia is easy to dissolve in water, while the dissolution rate of "granular ammonium bicarbonate" produced by filling auxiliary materials is slower. In addition, agricultural ammonium bicarbonate is not a licensed product, and the production process is not strictly regulated, so there is also a kind of "granular ammonium bicarbonate" or "long-acting granular ammonium bicarbonate" on the market. The raw material of this product is mainly ammonium bicarbonate accounting for about 70%, plus 20 kinds of auxiliary materials such as sepiolite, Maifan stone and so on. Therefore, the purchase of agricultural ammonium bicarbonate should avoid buying "granular ammonium bicarbonate" or "long-acting granular ammonium bicarbonate" these two types of ammonium bicarbonate.
