Can ammonium bicarbonate be applied with water (Can ammonium bicarbonate be applied with water)

Ammonium carbonate is the product of carbonization and centrifugal drying after carbon dioxide is passed into concentrated ammonia water. It has a nitrogen content of about 17% and has a strong pungent ammonia odor. It is highly hygroscopic and easily soluble in water. It is a fast-acting nitrogen fertilizer and is alkaline. The ammonium ions in ammonium carbonate are easily adsorbed by the soil and are not easily leached.

Ammonium carbonate is an unstable compound that easily decomposes and volatilizes at room temperature, and also easily deliquesces and clumps.

Ammonium carbonate is a very good nitrogen fertilizer. In the past, apple orchards, peach orchards and other orchards used ammonium carbonate as topdressing in spring. Just like corn, wheat and other crops, ammonium carbonate is also used as topdressing.

Ammonium carbonate is better used as base fertilizer and topdressing, and is generally not used as seed fertilizer, otherwise it is easy to burn seeds.

The application time of ammonium urea is generally in the low temperature season or when the temperature is low in the morning and evening, because the volatilization loss of ammonium urea is greatly related to temperature and moisture. The higher the temperature, the greater the volatilization loss, and the more moisture, the less the loss. Burying the soil reduces the contact area between ammonium urea and the air, and the loss is less.

Therefore, there are two major principles to follow when applying ammonium urea: one is that it cannot be separated from the soil, and the other is that it cannot be separated from water.

Therefore, urea ammonium nitrate can be applied with water, but it is best not to apply it at high temperatures. In addition, tender leafy vegetables should not be applied with water to prevent fumigation or burning of the leaves.

For example, nowadays corn stalks are basically returned to the fields before wheat is sown. The stalks will need a lot of nitrogen to rot in the soil, which leads to insufficient nitrogen in the soil and the wheat seedlings will turn yellow. Therefore, it is necessary to increase the application of nitrogen fertilizers, such as ammonium urea and urea, applied with water.

In addition, when the wheat turns green in spring, if the wheat seedlings turn yellow and the base number is insufficient due to nitrogen deficiency, you can also apply nitrogen fertilizers such as urea ammonium when watering the wheat seedlings.

Now the Dewdrop Early Peaches are about to be on the market. You can apply urea ammonium nitrate along with water about 20 days before harvesting, which will have a great effect on fruit swelling.

When I planted spring snow peaches a few years ago, every 15-20 days before harvest, I applied 30-50 kilograms of ammonium carbon per acre in combination with watering, and the effect was good.

The following points should be noted when applying ammonium carbonate:

1. Ammonium carbonate cannot be mixed with alkaline substances such as calcium magnesium phosphate fertilizer, wood ash, lime nitrogen, etc., otherwise it will accelerate the decomposition of ammonium carbonate into ammonia and volatilize away.

2. Although ammonium carbonate can be mixed with potassium chloride, it must be used immediately after mixing, otherwise the ammonium carbonate will also decompose and accelerate the volatilization loss of ammonia. This is because potassium chloride has high hygroscopicity, and ammonium carbonate is easy to decompose under humid conditions.

3. Ammonium carbon and superphosphate can be mixed and have the effect of increasing the fertilizer efficiency. Because superphosphate is acidic, part of the ammonium carbon will be converted into ammonium phosphate after the two are mixed, thus reducing the volatilization of ammonia.

For example, using ammonium urea plus superphosphate as base fertilizer for crops has more benefits than applying only one of them.

However, there are many grades of superphosphate. If the superphosphate you choose has a higher acid content, its hygroscopicity will increase. If it is mixed with ammonium carbon and stored for too long, it will also cause ammonia volatilization. Therefore, it should be applied as soon as possible after mixing.

4. Do not apply urea on rainy days, do not apply during droughts, do not apply under high temperatures and strong light, and it is best not to apply when there is dew, otherwise it will easily burn the leaves, stems and other parts of the plant if it gets on the plant .

【 Summarize 】

Ammonium urea is a good quick-acting nitrogen fertilizer with strong hygroscopicity and is easily soluble in water. When applying ammonium urea, it should be kept close to the soil and water. It can be dissolved in water and applied , but attention should be paid to the fact that high temperatures can easily damage leaves and other crop tissues.
