Why is the effect of ammonium bicarbonate good in spring?

What are the characteristics of ammonium bicarbonate? What is the effect of applying ammonium bicarbonate? Why does it work well in spring? Also ask experienced netizens to make a brief introduction. 1. Rapid fertilizer effect: compared with urea, urea can not be directly absorbed by crops after being applied to the soil, and a series of transformations should be carried out in accordance with the conditions before it can be absorbed by crops, and the effect of fertilization is later. Ammonium bicarbonate is absorbed by soil colloid immediately after it is applied into soil, which can be absorbed and utilized by crops directly, and can be effective on the same day. 2. Multiple absorption: ammonia and carbon dioxide are formed after ammonium bicarbonate is applied to the soil, and ammonia is used by crop roots; carbon dioxide is directly absorbed by crops as a gas fertilizer. 3. Deworming and sterilization: when ammonium bicarbonate is applied, the pests in the soil can be killed or driven away quickly, and harmful bacteria can be poisoned, so as to achieve the goal that crops are free from diseases and pests. 4. High performance-to-price ratio: compared with other nitrogen fertilizers with the same fertilizer effect, ammonium bicarbonate is more economical and affordable, and there is no residue after ammonium bicarbonate is absorbed by crops, which will not cause any harm to the soil. The planting network suggests that in the early spring, the fertilizer requirements for crops to return to spring (need to absorb a large amount of nitrogen fertilizer in time) are completely consistent with the unique characteristics of ammonium bicarbonate. therefore, it is suggested that ammonium bicarbonate should be applied in spring and buried fertilizer.
