1. Avoid foliar spraying of ammonium bicarbonate, which is highly corrosive to crop leaves, easily burns leaves and affects photosynthesis, so it cannot be used as a fertilizer for crop foliar spraying.
2. Avoid dry soil application. The soil is dry. Even if it is deeply covered, the fertilizer cannot be dissolved and absorbed in time and can be absorbed and utilized by crops. Only when the soil has a certain humidity and ammonium bicarbonate is applied, the fertilizer can be dissolved in time and the volatilization loss can be reduced.
3. Avoid high temperature application The volatility of ammonium bicarbonate is closely related to the temperature.
4. Avoid mixing ammonium bicarbonate with alkaline fertilizers. If ammonium bicarbonate is mixed with highly alkaline plant ash, lime, etc., or applied at the same time, it will lead to more volatile nitrogen loss and loss of fertilizer efficiency.
5. Avoid using ammonium bicarbonate mixed with bacterial fertilizer, which will emit a certain concentration of ammonia gas.If it comes into contact with bacterial fertilizer, the living bacteria in the bacterial fertilizer will die, and the yield increase effect of bacterial fertilizer will be lost.
6. Avoid using ammonium bicarbonate and calcium superphosphate mixed overnight after mixing with calcium superphosphate. Although the effect is better than applying separately, it should not be left for a long time after mixing, let alone overnight. Because superphosphate is highly hygroscopic, it will make the compost into slurry or agglomerate and cannot be used.
7. Avoid blending with urea. The root system of crops can not straight take in urea. Only under the activity of urease in the dirt can it be soaked up and made use of by crops after being converted into ammonium nitrogen; after ammonium bicarbonate is applied to the dirt, the soil solution will be acidic in a brief time.
8. Avoid mixing with pesticides Ammonium bicarbonate and pesticides are both chemical substances, which are easily hydrolyzed by moisture. Many pesticides are alkaline, and when the two are mixed together, chemical reactions are likely to occur, reducing fertilizer efficiency and drug efficacy.
9. Do not use ammonium bicarbonate with seed fertilizer, which is highly irritating and corrosive. After the ammonia gas that comes out during decomposition comes into contact with the seeds, it will smoke the seeds and even burn the seed embryos, which will affect germination and emergence. According to experiments, 12.5 kg of hydrogen carbonate per mu is used as wheat seed fertilizer, and the emergence rate is less than 40%.
10. Avoid topsoil application According to the measurement, when the temperature is 29~(2 o’clock, the ammonium bicarbonate applied to the topsoil will lose 8.9% of nitrogen in 12 hours, while the ammonium bicarbonate applied to the topsoil will lose 8.9% of nitrogen in 12 hours, while the deep application of 10 cm of cover will lose less than 1% of nitrogen in 12 hours. %.In the paddy field, the surface application of ammonium bicarbonate can increase the yield of paddy by 10.6 kg per kilogram of nitrogen, and the increase of rice yield by deep application is 17.5 kg. Therefore, the application of ammonium bicarbonate as a base fertilizer requires ditching or deep nesting on dry land. Apply 7-10 cm, cover soil and water while applying; paddy fields should be ploughed while ploughing, and rake after ploughing, so that the fertilizer can enter the mud and improve the utilization rate.
Ammonium bicarbonate is a sulfate-free nitrogen fertilizer.It is an ideal substance for crops to synthesize amino acids.
