What fields is ammonium bicarbonate suitable for? A detailed explanation of usage precautions

Ammonium bicarbonate has lower solubility than other solid ammonia fertilizers, but it dissolves relatively easily in water. It is itself a physiologically neutral quick-acting nitrogen fertilizer, and it is the variety with the lowest nitrogen content among solid nitrogen fertilizers.

Application fields

1. Used as a nitrogen fertilizer, suitable for various soils, it can simultaneously provide the ammonium nitrogen and carbon dioxide needed for crop growth, but its nitrogen content is low and it tends to cake;

2. Used as an analytical reagent, and also used in the synthesis of ammonium salts and the degreasing of fabrics;

3. Used as a chemical fertilizer;

4. It can promote crop growth and photosynthesis, stimulate seedling growth and leaf development, and can be used as a topdressing or directly applied as a base fertilizer. It is used as a food fermentation agent and leavening agent;

5. As a chemical leavening agent, China stipulates that it may be used in various foods that require the addition of a leavening agent, in an appropriate amount according to production needs;

6. Used as an advanced food fermentation agent. Combined with sodium bicarbonate, it can be used as a raw material for leavening agents in bread, biscuits, pancakes, etc., and is also used as a raw material for effervescent powdered fruit juice. It is also used for blanching green vegetables, bamboo shoots, etc., as well as in medicine and reagents;

7. It can be used together with sodium bicarbonate as a raw material for leavening agents in bread, biscuits, pancakes, etc. Baking powder also uses this product as its main component, combined with acidic substances. It is also used as a raw material for effervescent powdered fruit juice; when blanching green vegetables, bamboo shoots, etc., 0.1% to 0.3% is used;

8. Used as a topdressing for agricultural crops.

Precautions

1. Ammonium bicarbonate must not be mixed with alkaline fertilizers for application, in order to prevent ammonia volatilization and cause nitrogen loss.

2. Follow the “five no-application” rule: do not apply without mixing with fine soil, do not apply when there is dew, do not apply when it is raining, do not apply when there is no shallow water in the field, and do not apply under the scorching sun. If there is sufficient time for fertilization, it is best to make ammonium bicarbonate into ball fertilizer or granular fertilizer for deep application. In addition, during transportation and storage of ammonium bicarbonate, load and unload gently, keep the packaging tight, and store it in a dry and cool place. It must not be mixed with alkaline fertilizers or human and livestock manure, so as to avoid loss of effective fertilizer nutrients.

3. When applying, do not let it come into contact with crop seeds, roots, stems, or leaves, so as to avoid burning the plants.

4. It is not suitable for use as a seed fertilizer, otherwise it may affect seed germination.

5. Avoid mixing with bacterial fertilizer: after ammonium bicarbonate is applied, it releases ammonia gas. Contact with bacterial fertilizer will cause the living bacteria in the bacterial fertilizer to die, making the bacterial fertilizer ineffective.

6. Avoid foliar spraying: when ammonium bicarbonate is sprayed on the leaves, it easily burns the leaf surface and affects the photosynthesis of crop leaves.
