Ten taboos of ammonium bicarbonate application

One should avoid foliar application. Ammonium bicarbonate is highly corrosive to crop leaves and easily burns leaves, so it cannot be used as fertilizer for crop surface spraying.

Second bogey dry soil fertilization. The soil is dry, and even if it is covered, the fertilizer cannot be dissolved and absorbed in time for the crop to absorb and utilize.

Three bogey high temperature fertilization. The volatility of ammonium bicarbonate is closely related to the temperature. The higher the temperature, the more volatile it is. Therefore, ammonium bicarbonate should not be applied under high temperature.

Four bogey and mixed with alkaline fertilizer. Ammonium bicarbonate is mixed with alkaline ash, lime, etc., or applied at the same time, which leads to the loss of nitrogen and the loss of fertilizer efficiency. Therefore, ammonium bicarbonate should be applied alone.

Five bogey mixed with bacterial fertilizer. After the application of ammonium bicarbonate, a certain concentration of ammonia gas will be emitted. If it is in contact with the bacterial fertilizer, the living bacteria in the bacterial fertilizer will die, and the effect of increasing the productivity of the bacterial fertilizer will be lost.

Six bogey mixed with superphosphate and used overnight. The mixed application of ammonium bicarbonate and superphosphate is better than the single application, but it should not be put on for a long time after mixing, and it cannot be overnight. Because the hygroscopicity of superphosphate increases, the compost becomes slurry or agglomerate. Can not be used.

Seven bogey and urea mixed application. Crop roots can not directly absorb urea, only under the action of urease in soil, can be absorbed into ammonium after being converted into ammonium nitrogen. After ammonium bicarbonate is applied to the soil, the soil solution will be acidic for a short time, which will accelerate the nitrogen in urea. Volatile loss, so ammonium bicarbonate can not be mixed with urea.

Eight bogey mixed with pesticides. Ammonium bicarbonate and pesticides are chemical substances that are highly susceptible to moisture hydrolysis. Mixing the two together is prone to chemical reactions, reducing fertilizer efficiency and efficacy.

Nine bogey for seed fertilizer use. Ammonium bicarbonate is highly irritating and corrosive. After contact with ammonia and bacteria, the ammonia will smother the seeds and even burn the embryos, affecting germination and emergence.

Ten bogey applied to the topsoil. Apply ammonium bicarbonate as the base fertilizer, apply ditch or nest deep in the dry land for 7-10 cm, and apply water while spraying the soil; apply the side plow in the paddy field, plow after the plow, and let the fertilizer into the mud. improve the utilization.
