Ammonium bicarbonate has the advantages of low price, economy, non hardening soil, suitable for all kinds of crops and soils, and can be used as base fertilizer and topdressing fertilizer. So today, I’d like to share with you the role of ammonium bicarbonate, use methods and precautions, let’s have a look!

1. The role of ammonium bicarbonate

1. Fast and efficient

Compared with urea, urea can not be directly absorbed by crops after it is applied into soil, and a series of transformation must be carried out in accordance with the conditions to be absorbed by crops, and the effect of fertilization is later. Ammonium bicarbonate was absorbed by soil colloid immediately after it was applied into soil, and it was directly absorbed and utilized by crops.

2. Ammonia and carbon dioxide are formed when ammonium bicarbonate is applied into soil, which is used by crop roots; carbon dioxide is directly absorbed by crops as gas fertilizer.

3. When ammonium bicarbonate is applied to the soil, the pests in the soil can be quickly killed or driven away, and harmful bacteria can be poisoned.

4. Compared with other nitrogen fertilizers with the same fertilizer efficiency, the price of ammonium bicarbonate is more economical and affordable. After being absorbed by crops, ammonium bicarbonate will not cause any harm to the soil.

2. Usage of ammonium bicarbonate

1. As nitrogen fertilizer, it is suitable for all kinds of soil and can provide ammonium nitrogen and carbon dioxide for crop growth at the same time, but the nitrogen content is low and easy to agglomerate;

2. It can be used as analytical reagent, synthesis of ammonium salt and degreasing of fabric;

3. As chemical fertilizer;

4. It can promote the growth and Photosynthesis of crops, accelerate the growth of seedlings and leaves, can be used as topdressing, or as base fertilizer, as food fermentation agent and expansion agent;

5. As a chemical leavening agent, it can be used in all kinds of food that need to be added with leavening agent, and it can be used appropriately according to the production needs;

6. It can be used as food advanced starter. When combined with sodium bicarbonate, it can be used as raw material of leavening agent such as bread, biscuit and pancake, and also used as raw material of foaming powder juice. It is also used for blanching green vegetables, bamboo shoots, medicine and reagents;

7. Alkali; leavening agent; buffer; aerator. It can be used with sodium bicarbonate as raw material of leavening agent for bread, biscuit and pancake. This product is also used as the main ingredient in the fermentation powder, together with acid substances. It can also be used as raw material of foaming powder juice, and 0.1% – 0.3% for blanching green vegetables and bamboo shoots;

8. It is used as top dressing for agricultural products.

9. Ammonium bicarbonate has the advantages of low price, economy, non hardening soil, suitable for all kinds of crops and soils, and can be used as base fertilizer and topdressing fertilizer. It is a widely used nitrogen fertilizer product in China except urea.

3. Notes on use of ammonium bicarbonate

1. Avoid spraying ammonium bicarbonate on the leaves of crops, which has strong corrosivity to the leaves, easy to leave and affect photosynthesis, so it can not be used as fertilizer for foliar spraying.

2. Do not use dry soil. The soil is dry. Even if the fertilizer is deeply covered, the fertilizer can not be dissolved in time and absorbed and used by crops. Only when the soil has a certain humidity, the fertilizer can be dissolved in time and the volatilization loss can be reduced by applying ammonium bicarbonate.

3. Avoid using ammonium bicarbonate at high temperature. The higher the air temperature, the stronger the volatilization. Therefore, ammonium bicarbonate should not be applied in high temperature and hot sun.

4. Avoid mixed application of ammonium bicarbonate with alkaline fertilizers. If ammonium bicarbonate is mixed with plant ash and lime with strong alkalinity, it will lead to more volatile nitrogen loss and loss of fertilizer efficiency. Therefore, ammonium bicarbonate should be applied alone.

5. Avoid mixing with bacterial fertilizer with ammonium bicarbonate, which will emit a certain concentration of ammonia gas. If contact with bacterial fertilizer, the living bacteria in the bacterial fertilizer will die, and the effect of increasing production of bacterial fertilizer will be lost.

6. Do not use ammonium bicarbonate and superphosphate overnight after mixing with superphosphate. Although the effect is better than single application, it is not suitable to leave it for a long time after mixing, let alone overnight. Because of the high hygroscopicity of SSP, the mixed fertilizer will become paste or caking, and can not be used.

7. Do not mix with urea, crop roots can not directly absorb urea, only under the action of urease in the soil, can be absorbed and utilized by crops; after ammonium bicarbonate is applied into soil, the soil solution will become acidic in a short time, which will accelerate the loss of nitrogen in urea, so ammonium bicarbonate can not be mixed with urea.

8. Avoid mixing with pesticides. Ammonium bicarbonate and pesticides are chemical substances, which are prone to hydrolysis due to moisture. A lot of pesticides are alkaline. When they are mixed together, they will easily produce chemical reactions and reduce fertilizer efficiency and efficacy.

9. Avoid using ammonium bicarbonate with seed fertilizer, which has strong irritation and corrosivity. After contacting the seeds with ammonia gas running out during decomposition, the seeds will be fumigated, and even the embryo will be burned, which will affect the germination and seedling emergence. According to the experiment, 12.5kg/mu of hydrogen carbonate is used as wheat seed fertilizer, the emergence rate is less than 40%; if ammonium bicarbonate is sprayed on the rice seedling field, and then sowed, the rotten bud rate is more than 50%.

According to the measurement, when the temperature is 29 ~ (2), the nitrogen loss of ammonium bicarbonate applied on the surface soil is 8.9% in 12 hours, while the nitrogen loss is less than 1% in 12 hours when the cover is 10 cm deep. In paddy field, ammonium bicarbonate surface application, equivalent to per kilogram of nitrogen, can increase rice yield by 10.6 kg, and deep application can increase rice yield by 17.5 kg. Therefore, when ammonium bicarbonate is used as base fertilizer, furrow or burrow should be opened on dry land, and the depth should be 7-10 cm, covering soil and watering while applying; in paddy field, ploughing should be done at the same time and harrowing after ploughing to make fertilizer into mud and improve utilization rate.
