Which methods cannot be used when applying agricultural ammonium bicarbonate? Please adviseThe following methods cannot be used when applying ammonium bicarbonate:
1. Foliar spraying:Ammonium bicarbonate is highly corrosive to crop leaves and easily burns them, so it cannot be used as a fertilizer for foliar spraying.
2. Applying to dry soil:When 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. Applying at high temperatures:The volatility of ammonium bicarbonate is closely related to air temperature; the higher the temperature, the more intense the volatilization. Therefore, ammonium bicarbonate should not be applied under high temperatures and scorching sun.
4. Mixing with alkaline fertilizers:Mixing ammonium bicarbonate with strongly alkaline materials such as plant ash and lime, or applying them at the same time, will cause nitrogen loss through volatilization and reduce fertilizer efficiency, so ammonium bicarbonate should be applied alone.
5. Mixing 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. Mixing with superphosphate and leaving it overnight before use:Although mixing ammonium bicarbonate with superphosphate has a better effect than applying them separately, the mixture should not be left for long after mixing, and even less should it be left overnight, because the increased hygroscopicity of superphosphate will turn the mixed fertilizer into a slurry or cause it to cake, making it unusable.
7. Mixing with urea:Crop roots cannot directly absorb urea; it can only be absorbed and used by crops after being converted into ammonium nitrogen under the action of urease in the soil. After ammonium bicarbonate is applied to the soil, it causes the soil solution to become acidic in the short term, which accelerates the volatilization loss of nitrogen in urea, so ammonium bicarbonate cannot be mixed with urea.
8. Storing together with pesticides:Both ammonium bicarbonate and pesticides are chemical substances and are highly prone to moisture absorption and hydrolysis reactions. Placing them together easily causes chemical reactions, reducing fertilizer efficiency and pesticide effectiveness.
9. Using as seed fertilizer:Ammonium bicarbonate is strongly irritating and corrosive. The ammonia gas released during decomposition, upon contact with seeds, will damage the seeds and even burn the seed embryos, affecting germination and emergence.
10. Applying on the soil surface:When applying ammonium bicarbonate as a base fertilizer, on dry land it should be applied deeply in furrows or holes at 7-10 cm, covering with soil and watering while applying; in paddy fields, it should be applied while plowing, and harrowed immediately after plowing, so that the fertilizer enters the mud and utilization is improved.
