How should ammonium bicarbonate not be used? What should be noted when using ammonium bicarbonate? Is there any friend who knows about this who can share?1. Ammonium bicarbonate must not be sprayed on leaves: ammonium bicarbonate is highly corrosive to crop leaves and easily burns them, so it cannot be used as a foliar fertilizer for crops.
2. Ammonium bicarbonate must not be applied to dry soil: because the soil is dry, even with deep application and covering, the fertilizer cannot dissolve and be adsorbed in time for crops to absorb and use.
3. Ammonium bicarbonate must not be applied at high temperatures: the volatility of ammonium bicarbonate is closely related to the air temperature; the higher the temperature, the more intense the volatilization, so ammonium bicarbonate should not be applied under high temperatures and blazing sun.
4. Ammonium bicarbonate must not be mixed with alkaline fertilizers: mixing ammonium bicarbonate with highly alkaline plant ash, lime, etc., or applying them at the same time, will lead to volatilization and loss of nitrogen, reducing fertilizer efficiency, so ammonium bicarbonate should be applied alone.
5. Ammonium bicarbonate must not be mixed with bacterial fertilizer: after application, ammonium bicarbonate releases a certain concentration of ammonia gas. If it comes into contact with bacterial fertilizer, it will kill the live bacteria in the bacterial fertilizer and cause it to lose its yield-increasing effect.
6. Ammonium bicarbonate must not be mixed with superphosphate and left overnight before use: although mixing ammonium bicarbonate with superphosphate before application works better than applying them separately, the mixture should not be stored for long after mixing, and certainly not overnight, because the increased hygroscopicity of superphosphate will turn the mixed fertilizer into a slurry or cause it to cake, making it unusable.
7. Ammonium bicarbonate must not be mixed with urea: generally, crop roots cannot directly absorb urea; only after it is converted into ammonium nitrogen under the action of urease in the soil can it be absorbed and used by crops. After ammonium bicarbonate is applied to the soil, it causes the soil solution to become acidic for a short time, which will accelerate the volatilization loss of nitrogen in urea, so ammonium bicarbonate must not be mixed with urea.
8. Ammonium bicarbonate must not be stored together with pesticides: ammonium bicarbonate and pesticides are both chemical substances and are highly prone to moisture and hydrolysis reactions. Storing the two together easily causes chemical reactions and reduces fertilizer and pesticide efficacy.
9. Ammonium bicarbonate must not be used as seed fertilizer: ammonium bicarbonate is highly irritating and corrosive. The ammonia gas released during decomposition, upon contact with seeds, will fumigate and damage the seeds, or even burn the seed embryo, affecting germination and seedling emergence.
10. Ammonium bicarbonate must not be applied on the soil surface: when applying ammonium bicarbonate as a base fertilizer, on dry land it should be placed in furrows or holes at a depth of 7~10 cm, applying while covering with soil and watering; in paddy fields, it is best to apply while plowing, and harrow immediately after plowing so that the fertilizer enters the mud and its utilization rate is improved.
